it is as accurate as its bigger brothers, the gps reciever works well even when driving i use it in my car.

i bought it for misty days on the water off my kayak and offshore use off the boat, when i do manage to get squeezed in .

it is user friendly and easy to use and i like the floating and waterproof features!
