Suunto T6 Watch Review

Suunto T6 Watch
Average Reviews:

(More customer reviews)
I have raced bikes and triathlons for over 20 years, and used heart rate monitors since the early 1990's when they were 'brand new' to sports. After buying and using at least 6 different systems, most of them Polar-made, I have come to the conclusion that there are two paths worth taking in HRMs- you can keep it simple and buy a low-cost, quality device that gives your average and training time, or you should go high-end and buy a device that you can download to your PC and thoroughly analyze the data. The gear in the middle provides little added value in my opinion.
I have been sponsored by other companies in the past but never by SUUNTO, so this review is completely based on personal experience.
I have used this HRM system for over a year and it is hands-down one of the best training aids I have ever spent money on. It is expensive, but see my comments above. And the software you get coupled with SUUNTO's Olympic-level research into the science of EPOC and physiology make this an invaluable training tool. Why? Because the hardest thing to know when you have an HRM is how hard to train, and what impact the time you spend training at a given intensity level has on your fitness. It's like having a tachometer on an engine but no speedometer or fuel gauge-- you don't know how fast to go or how far to go to get the most out of a tank of gas. EPOC makes a big difference and you'll be surprised at the improvements in your training efficiency. Wasted miles are the bane of a working athlete's existence and this tool helps reduce them.
I've used the T6 with a running pod for nearly two years, and it's at least as accurate as my Garmin Etrex GPS unit. I do take the time to check the calibration every now and then, and even during a race if it's off, it's never off by much and it's consistent so I can mentally compensate for any differences. I've used the shoe pod to pace marathons on roads and ultra-marathons in the woods. I was first aware of the technology in 1999 when a team I was part of was given a similar system to test in the Himalayas during an adventure race- it was OK then, but now it works. We used my T6 and shoe pod during an adventure race in the Great Smokies in 2006 as a navigation aid (not by itself) by measuring distances at night in a major snowstorm. It was probably not perfect but it definitely helped keep us from getting lost. Handheld GPS wouldn't work in that kind of environment of heavy cover and falling snow.
The bike pod for my T6 hasn't been as good a story, but there are new versions out now that appear to have addressed the issues- the biggest one lies in the distance between the pod and the watch- the transmission range was not long enough to make it work well, you had to mount the watch on the bike as opposed to keeping it on your wrist. I believe that the new pods have improved this but I haven't tested them myself.
The other complaint I'd offer is that you have to send the T6 to SUUNTO for software updates. I had a watch go bad early on, and the replacement had an older software revision in it that I have yet to update because of the mail-in requirement-- but I'll do it sometime soon as my training schedule permits. The good news is that updates are free, and you don't really need them unless you want the new features they offer which are usually pretty minor changes. To be fair, last time I checked, Polar requires you to send them an HRM for new batteries, with the SUUNTO gear you can change them all yourself, including the HR strap. The HRM will NOT work in a pool though, and my Polar HRMs are spotty in the water but sometimes work.
I've used my T6 to train for an Ironman triathlon, multiple ultra-distance road and MTB events, a couple of ultra-distance runs, and other events noted above-- with the exception of my newly-acquired power training gear for my bike, my T6 is absolutely the most effective piece of training gear I have ever owned, and I wish I'd had this ten years ago when I was really competitive. It's an amazing piece of gear and I'm a better athlete because of its use- you have to spend some time learning about EPOC and exercise science but the T6 more than pays it back.

Garmin 305 Forerunner Review

Garmin 305 Forerunner
Average Reviews:

(More customer reviews)
I use mine for cycling and running, the direct link to see your workouts mapped on GOOGLE EARTH is FANTASTIC!!!! (the included software is far more stable than the junk Polar included with their HRM's.
Heart rate strap with replaceable battery is coded and comfortable. It's better in my opinion than the Polar products (of which I've owned three)
This is much better than the Forerunner 201 which I previously owned (locks on satellites 10 times faster) and I'd avoid the 405 unless you really want to use this watch as a normal day to day wristwatch (check out the 405 reviews)
One nice feature is being able to customize the display screens. Another review criticized the 305 for the numbers being too small to read while exercising. I don't have an issue but would point out that you can significantly increase the size of the display by simply displaying fewer fields.
My only complaint is that it's easy to leave it on and run the battery down - which is a bummer if you're just about to work out. I wish there was an "auto off" feature which would shut it down if it detects no movement or heart rate within an hour or so. Fortunately, with Li-Ion batteries, as little as a 10 minute charge gives you enough juice for a 90 minute run.
If you've found this review to be helpful, please let me know!

Suunto X9i GPS Altimeter Compass Review

Suunto X9i GPS Altimeter Compass
Average Reviews:

(More customer reviews)
I found the remarks of the one other positive reviewer quite a relief: the guy who pointed out that good performance of the GPS (i.e. the key unique feature distinguishing this watch from other Suunto models) hinges critically on whether or not you first get your satellite 'fix' properly. I have found that, if you wait the very first time you use it, to get a proper (not flashing) firm fix, then subsequent fixes have been relatively rapid (usually around 2 minutes in an urban environment. Once you have a lock-on, then subsequent performance is relatively fine.
I have a few minor gripes about the software visualisation. When it does loose satellite connection, rather than not graphing for the drop out period of time, the software includes the squiggly deviations to route when it can't locate you. This has the consequence that some journeys appear like I fly around or walk on water. This is not the case. I would prefer just blanks for drop-out periods of time. Any GPS device works much better in open spaces rather than built-up urban ramblings.
As a watch model, the comparable device is the Garmin forerunner. The Garmin probably has more 'stickability' and usability for its GPS (I have Garmin handheld for comparison). Its greater reception and stronger GPS reception is due to its bigger aerial. That means it's also bigger and probably emitting strange things into your arm. The battery life on Garmin receivers is very frustrating and I have had no problems with the x9i though its continual GPS use would be limited to 4-5 hours. Personally, I am prepared to live with the slightly more delicate reception of the x9i in order to use a much more elegant device. The watch looks like a watch and its smooth contours and rubberised grippy surface have design aesthetics and simplicity of display that Garmin doesn't. If you primarily (or only) use GPS, buy the Garmin. If you are concerned about looks and multi-function and if you are patient to setup a good connection first time, I think you will be pleasantly rewarded by this watch. I really like that it charges off my USB. Also, using Desktop Parallels and Win XP, I exchange the data into Trek Manager and X-loader uploading to Google with my Macbook ;-)

Garmin Forerunner 201 Waterproof Running GPS Review

Garmin Forerunner 201 Waterproof Running GPS
Average Reviews:

(More customer reviews)
Overall the Forerunner 201 works well for bicycling, although I wouldn't discard my conventional bike computer for several reasons:
1. In Speed mode (vs. Pace mode) there's no option to average out the readings, and the unit is too sensitive to motion. With the GPS mounted on a bike and the bike at a complete stop, tiny motions of less than 1 cm continuously trigger the autostop/autostart, so it keeps beeping and accumulating elapsed time and distance. Setting the Auto Pause threshold to a non-zero value mitigates this problem at a slight risk of false pauses.
2. The % grade (custom) readout is highly erratic. If you're moving too slowly (less than 5 mph), even if you're burning your lungs on a climb, it may read 0% or even a negative number like -3%! Seems like there may be a math underflow bug in the algorithm when the vertical displacement is too small over successive readings.
3. The altitude reading is not credible when you don't have a clear view of the sky. The unit seems to extrapolate from the last trend it had to "update" the readout, rather than indicating that it's unable to read the altitude. I was on King's Mountain Road (SF Peninsula) under tree-cover, came out into an open spot and the altitude reading jumped by over 500 feet when the GPS got an actual reading from the satellites. There are 2 stretches like this on the climb, and it happened both times.
Enabling Auto Lap in the Training Assistant mode sets the GPS to record trackpoints (time, latitude, longitude and altitude), supposedly at fixed distance intervals, the finest preset value being 1 mile. At firmware version 3.40, the current track can hold 3000 points, with the oldest points being overwritten by the newest when you exceed 3000.
You might think this means you can go 3000 miles without losing any data, but it seems to sample more often than at 1 mile intervals. I've found that after about 7 hours, I start getting my oldest trackpoints overwritten. The only way around it is to remember to stop the timer, reset, then start the timer: this starts a new track (the previous track is still in the unit's memory until you clear History).
The Windows-only Forerunner Logbook application downloadable from Garmin's website is able to download tracks and display (a) speed or pace vs. time, (b) map of the route (from timer start to timer stop), (c) altitude vs. time. There were some goofy data for my most recent ride which showed me exceeding 80 mph(!), probably caused by gaps when the GPS signal was too weak to register. The Logbook application can also export the data as an XML file where each data sample contains Zulu time, latitude, longitude and altitude (in meters, regardless of your settings on the Forerunner or in Logbook). However, the format seems not be recognized by any program (including Forerunner Logbook; i.e., it doesn't know how to read the XML file it wrote!), making it of rather dubious value. Garmin's more recent Training Center (again Windows-only) app does better. GPSBabel (and MacGPSBabel) can now translate LogBook's XML to other formats, including HikeTech (see below). With your track data in GPX format you can use, FlightTrack (Mac OS X) to make dynamic 3D maps overlaid on digital terrain models; and the web-based GPS Visualizer (www.gpsvisualizer.com) to overlay tracks on hi-res satellite/aerial photos, generate elevation profiles and generate kml or kmz files to load into Google Earth (download from earth.google.com, Win 2000, XP, OS X 10.3.9 and 10.4.x only).
I found the pins securing the wrist strap impossible to budge with a screwdriver, as stated in the manual. I had to take it to a watch repair shop where the repairer used a "jeweler's band pin removing tool" -- with some careful effort -- to pop the pins in order to remove the wrist strap. So it seems you either leave the wrist strap on or off (or buy the jeweler's tool): it's too difficult to switch around.
Why is Garmin still stuck on serial port interfaces? USB has been around for a few years now and is much easier to deal with. It would also be friendlier if you didn't have to use the charger cradle in order to connect to a computer. The standard charger sold in the US is 120v only. It wouldn't have cost much more to design a universal 120-240v charger for worldwide use. Garmin's MSRP for their 240v version is an outrageous $32.90! (It can be found mail-order for around $20.)
The owner's manual is pretty minimal. It doesn't explain the elements of the Map Mode display. Perhaps it works well at walking/running speeds, but on a bike I can't pay attention to the road and simultaneously focus on its tiny symbols. And on most rides the display is too small to cover the range of the entire route without the waypoints/auto lap points overlapping.
Once again we Mac (and Linux and even Win 95) users are ignored by a manufacturer when it comes to software support. The only way to update the firmware is with a Windows PC because the firmware is wrapped up inside a Windows-only "Updater" executable. On a Mac, you can use a serial-to-USB adapter cable and Virtual PC running Windows 98 or later to update the firmware. You may have to install a Windows driver from the manufacturer of the adapter cable. In my case, I also had to tell Virtual PC that COM1 was the "usbserial0" port on my Mac.
For Mac OS X, I found a set of 3 shareware programs from HikeTech.com to be useful. They are: (1) Link2GPS for transferring waypoints to/from the GPS and downloading tracks from the GPS; (2) TopoDraw to display tracks as a 2-D map (you can even overlay tracks on digitized maps as long as you have at least 3 waypoints you can identify on the map to establish its scale and relationship to the track data); (3) gpswrite to chart altitude vs. distance, speed vs. distance. The 3 programs work together using files in GPX format.
NEWER ALTERNATIVES (at higher prices, of course): In 2006, Garmin has 2 newer lines of sports-oriented GPS units. The Forerunner 205 is a wristwatch unit with all the features of the 201, a smaller-but-higher resolution screen, and more sensitive GPS circuitry and faster satellite sync. It comes with a 120v/60Hz charger only, no international version. There's a model 305, which adds a heart-rate monitor. Another new series is the Edge, aimed squarely at cyclists. The 205 is the basic model, the 305 the higher-end one, which adds cadence and/or HRM and a barometric altimeter. The Edge series has a larger grayscale screen, better sensitivity and faster satellite sync, and offers a 240v/50Hz charger as an optional accessory.

Finally, an alternative to awkward pedometers and cycling computers. The Forerunner 201 offers athletes an easy-to-read display and integrated GPS satellite receiver that provides precise speed, distance, and pace data--all in one compact unit that straps to your wrist. It’s a lightweight, accurate training assistant with performance tracking, auto-lap, auto-pause and more. And because it is a high quality Garmin GPS device, you get many of the features GPS users have come to rely on, such as precise latitude, longitude, altitude data. Choose either the 201 model for rechargeable power or the 101 if you prefer to use 2 AAA batteries. The Forerunner 201 is easy to use right out of the box and delivers the benefits of GPS technology at an affordable price.
To please folks who are passionate about their exercise and training, Garmin has added something special to the Forerunner 201 called the Virtual Partner. The feature allows you to set your training goal by configuring your Virtual Partner’s pace and workout distance. You'll get a graphic perspective of your performance by viewing your pace in relation to your Virtual Partner’s pace, so you can always see at a glance if you're keeping up or falling behind.
Almost as important as the training device itself are the accessories to integrate it with your active lifestyle. If you're into cycling, the best way to keep an eye on your GPS while you ride is with a bike mount bracket that straps to the handlebars of your bike, motorcycle, or whatever you're traveling with for easy viewing.
Other Forerunner 201 features: Mark specific locations, and then look-up and navigate to these points using an electronic map. Retrace your steps to a starting point or reverse your normal route for routine variation. Amount of calories burned can be tracked and calculated over the course of a workout. Lap history--such as lap time, lap distance, and average pace--can be stored for up to two years. Performance data can be automatically archived and calculated to provide an accurate record. Automated stopwatch provides auto-lap and auto-pause features. Lap timer indicates when a certain speed is reached or when you’ve fallen below a pre-set level. Pace whistle sounds alert when you begin traveling slower or faster than your desired pace. Distance whistle sounds when you reach a specified duration or distance in your workout. Download free Garmin software to transfer data from your Forerunner 201 to your PC for storage and analysis.

Garmin Forerunner 310XT Waterproof Running GPS With USB ANT Stick Review

Garmin Forerunner 310XT Waterproof Running GPS With USB ANT Stick
Average Reviews:

(More customer reviews)
I felt compelled to write a review, because I am disturbed with what some other reviewers are publishing. This is the best watch of it's kind I have owned, and as long as a purchaser understands what it does, and it's limitations, I think they will be more than satisfied. It may be that this watch will not meet their needs, but it should not be a cause to deliver a poor rating.
I have owned the Forerunner 305, the 201, the Timex GPS and a Polar, so I have years of experience. Since I do triathlons, I was most looking forward to the waterproof controls, and 20 hour battery. The charger is a bit funky design, but for me it seems to work just fine. My battery has been lasting at least 16 hours--I haven't tested it further before recharging. One issue that I had with the 305 also, though: the watch should be TURNED OFF while you are charging. If not, as soon as you disconnect the charger, since the watch is ON, it will start "discharging" (as it does normally while it is on. I have been caught several times with a depleted battery on my 305 because of this quirk--I think the watches should be programmed to automatically turn themselves off when the charger is connected).
I have used the new watch swimming, biking and running and hiking, and I am pleased with the performance for each sport. One reviewer pointed out that there should be a "swim" mode--I agree, but I think Garmin may have avoided that mode because the GPS does not work well in the water. Several reviewers complained about that, however Garmin does write on their website AND in their manual that the GPS does not work well in the water (I don't know that I would blame that on Garmin--probably the technology is just not there yet--besides, GPS signals do not penetrate water.) In fact, I did NOT get an accurate GPS distance reading for open water swimming, but it did map my COURSE correctly, albeit with a lot of zig-zags (I know I can't swim in a straight line, but I am not THAT bad).
The biking portion works great. The Garmin matches pretty closely with the distance measured on my bike computer (I don't have the Garmin bike sensor--I want that and the quick-release mount for my next birthday). Of course it also tracks speed, altitude, heart rate, etc. (I used the heart monitor strap from my 305).
Running works well also, basically same as biking although I do set up the display screens differently.
Other, useful new features I have noticed:
1. The watch locks onto satellites more quickly than my 305
2. The watch vibrates, although I wonder how this affects battery life. For instance it vibrates every lap (if I set it) so I know I have completed an autolap without having to look at the watch.
3. The software is more refined (lots of small fixes. For instance the settings function lets me know what sport mode I am in--although I think this could still be made easier and less confusing. And the time zone can be put on automatic--I always wondered why they couldn't do this before--the watch knows where it is for gosh sakes. And there are extra custom screens if you want them--statistic hounds take note.)
4. Wireless data upload. Very nice! Their new "Garmin Connect" site is also pretty useful, and the data can be uploaded directly to the Internet.
5. The 310XT is not much smaller or lighter than the 305 (according to the specs), but it FEELS MUCH smaller and lighter.
6. There is a progress bar for the battery charging. I would like to be able to see how much time is LEFT in my battery--I wish Garmin would add this.
In summary, I think this is far and away the best GPS watch Garmin has made, and is especially appropriate for triathletes (despite the swimming issue). You DO need to become accustomed to using the watch. Although I do not think it is hard to use, you SHOULD read the manual. At least you do not have to keep RE-reading the manual like I do for some other gadgets. I do think this watch is way overpriced, but I am a gadget freak, and I'm sure the price will come down over time, like it did for the 305 (which is a great deal, now, btw, if you don't need a 20 hour battery-life and a waterproof stopwatch :)

Garmin Forerunner 305 GPS Receiver With Heart Rate Monitor Review

Garmin Forerunner 305 GPS Receiver With Heart Rate Monitor
Average Reviews:

(More customer reviews)
I like this thing quite a lot. I've had it for about three weeks, and have used it on 12 workouts so far. I use it primarily for running, with biking a secondary usage. The main reason I wanted it was for the instantaneous readout of distance, running pace and heart rate, the latter needed for the speed work I want to do this running season.
The core functionality (distance and heart rate monitoring) works perfectly. There's none of the signal drops I've had with other heart monitors. Once the satellites are initially acquired, I've only had one dropout when I was outside. The initial acquisition of the satellites can be quirky and can take some time. The accuracy (according to the readout) is +/- 25ft, depending on how many satellites can be found. I've compared the distance measurement on the GPS with a known, measured distance on one of the trails I run on (the Chicago lakefront path). The GPS always increments a mile when I'm within 5 or 10 feet of the mile marker sign on the path. Well, I guess that's the least I should expect from a $350 GPS unit! Of course it's bigger than a normal running stopwatch, but that hasn't bothered me at all. The heart rate strap is also very comfortable and well-designed.
The display is crisp and has one outstanding feature: The information presented on the various pages can be completely user-customized. The default screen layout is rather poor, but in just a few steps I could replace it with the information I wanted to see while I run. There are almost 40 different data fields you can choose from for display. Examples: current pace, average lap pace, average run pace, heartrate, distance.
The only disappointment is the point-in-time (instantaneous) pace measurement: It varies wildly during a run. I see swings as big as +/- 3 minutes/mile. I'm a marathoner and I know my pace is fairly consistent during a run. I just looked at my run today, and according to the data the first mile varied from 5:57/mile to 12:06 mile. I suspect the problem is either in the averaging algorithm (too short a distance?), or in the uncertainty that results from different satellites coming in and out of view. The variations seem to get worse under tree cover compared with an open area. Luckily there's a lap-average pace that can be presented, and at least that value is useful and more accurate. The bottom line is that you can't look at the watch and say "right now I'm running 9 mins/mile". There is the ability to specify a pace smoothing factor, but I have it maxed out and still see the variations. The elevation readout also seems inaccurate, but that isn't important to me.
Upload of workout data to the PC software (Training Center) is transparent. The PC software is very good for presenting time/distance/pace/heartrate/calorie data. However the maps it shows are very crude. I've worked a bit with one of the online, subscription services (MotionBased). That looks really good and provides some additional functionality beyond the included Training Center software, although I still haven't decided if it's worth the $$$ yet for long-term data storage. MotionBased allows export to Google Earth, and it's tremendously cool to see your running path superimposed on a satellite image. You can recharge the unit through the USB port on your computer, although it's slower than using the dedicated recharger.
I had hoped that owning this device would prove motivational for me, and indeed it has. I can't imagine running or biking without it. Updating my training log is trivial now: Plug this thing into my computer, and it's done. My hope is that a future software update will do something about the pace calculation (maybe a few additional levels of smoothing?). If so, the Forerunner 305 would earn 5 stars+++.Positives:
Flawless heart rate sampling
Great distance measuring and lap-average pace calculation
Seamless integration with a PC
Fully-automatic training log update
User-customizable displayNegatives;
Wildly-varying pace readout.
