Average Reviews:
(More customer reviews)I've used many little bluetooth GPS units before because I develop land surveying equipment. I've also used many survey grade recievers that cost $40K. I know what I am talking about.
This one is by far the best cheap hand-held unit I've used. Battery lasts for ages and the satellite acquisition is really fast compared to other chipsets. I left it sitting outside for a week once, still turned on, and due to the power save mode it still worked when I remembered about it a week later and reconnected. Ran for another 8 hours or so before it finally ran out of juice.
It will even get satellites in a basement under a 2 story house. Of course, the location isn't very accurate, but the fact that it even gets a signal is very impressive.
Size-wise it is smaller than a deck of cards - about the size of a really small flip cell phone. 3 AA batteries together, and one lengthwise across them endwise is the approximate size.
Can't go wrong with this unit. It is standard bluetooth serial port profile (SPP slave) and streams NMEA data the moment you connect. The strings it supports are GGA,GSA,GSV,RMC.
