GT-31: Genie GT-31 Waterproof Sport GPS Data Logger with SD Expansion Slot Review

Average Reviews:

(More customer reviews)I bought this unit to use while windsurfing. The box indicates it is waterproof and that it is mainly used for windsurf. Well, it IS NOT waterproof after you open the cover a few times to access the card . It requires a waterproof pouch that you need to buy extra. If you don't, even traces of water will make it fail, as happened to me after using it less than 7 times, but as usual, just a few days after the warranty expired.
It is not vey user friendly and the manual is pretty poor. Cumbersome to reset max. speed, time sailed, etc. You basically have to reset each variable individually, one by one, that means taking it out of the pouch, etc. etc. Then, the registers of max speed, you have NO IDEA when they happened, if you are looking at recent or old data, etc. etc.
It basically comes without any software. If you want to see your tracks and other information, so it is usable.... yes, you guessed right, you have to buy it extra.
My unit also "froze" while making an action on the card menu. I do not remember if it was during formatting it or while removing it. The unit froze and would not even turn off. I had two options a) Wait two days until the battery died or b) Open the unit to access the battery inside (multiple really small screws, which would likely VOID the warranty....). It sucked, a lose lose situation.
The whole think has a look of old technology. Shortly you will be able to get all this can do in a smart phone with GPS, and much more, it is only a matter of somebody developing the application (maybe somebody already did). You would just put the phone in a pouch and avoid this gadget. Almost useless now, totally useless shortly. Who really wants to use a device in your arm, that you can not see while sailing????? Was it so hard to make something you can wear in your wrist? And that is REALLY waterproof???
