After testing this GPS side by side with my Delou gps for a while, I have no hesitation in saying this is the best GPS I've ever used. (Keep in mind its only the second I've used.)
Compared to the delou, it locks from cold much more quickly, it maintains lock much better, it has a stronger lock signal on the satelites it locks onto, and typically has about twice as many locked satelites as the delou.. especially in low signal conditions.
I brought it inside to test it out.. I wasn't expecting much, since the delou barely sees any satelites, and never locks any of them.. even when its beside the window. What happened when I connected it up nearly made me crap my pants. I got 10 satelites in view, and it connected to 7 of them!!! This is just sitting on my bedpost beside my computer desk, which is about 12 feet from the only window in the room. It wasn't open, is regular sized, and the blind was even drawn!
I'm really impressed with this unit, the reception is terrific, it works flawlessly, even in thick urban areas.. (I couldn't test how foilage affects it, since its winter here). The build quality of the unit is great too. Solid metal construction, the size of a credit card, and a good finish.
I have no reservations recommending this unit to anyone.
(I thought I should specify this is a shot taken from inside my bedroom of the locks I get.)
