Look what I’ve fished out from our CG forums – a Cell Phone + GPS tracker + GPS datalogger + watch. I don’t even know what to call it in the first place, but apparently it prefers to be known as the Wrist Tracker. This multi-functional device features integrated GPS and GSM modules complete with a high performance antenna. You will be able to configure its system settings through SMS or USB, and I believe the latter will be the more affordable method. The LCD display shows a variety of information such as system setting, your current coordination data and satellite indicator among others. It will transmit both longitude and latitude coordinates to your cell phone via SMS and can also be tracked online in real time by GPRS. No idea on how much this puppy will cost though.
