Compared to Garmin GPS18 puck, Argent GT-525 and several SatNavs (Garmin and Navman) this unit is MUCH better at getting a lock.
The magnetic base holds well. A suction mount accessory would be handy for windscreen mount. Use a bulldog clip to stick it to non-ferrous locations.
Fits OT+ and Tracker2 perfectly; just make sure you set the jumper to 5V !
If you need a 5V serial GPS receiver then this is the one.Rating: [5 of 5 Stars!]
