I bought this unit to start goe-caching. So-far I have found it to be as accurate as any other brand providing, as the manual says, I have a "clear view of the sky". I have checked its positioning against every cache I have found so far and it is typicaly within 2 or 3 meters. Assuming that other geo-cachers use all sorts of brands I figure this is a pretty fair test. I am learning about the limits of the GP system itself along the way. I get the feeling some reviewers are blaming those limits on this unit (maybe because its price is very 'competitive'?)
It is intuitive to use, I hardly had to look at the manual. The buttons are a little stiff. I like the rubber on all the corners of the case making so it can bounce around in my glove box without geting banged up. It is very waterproof. I have been caught out in some heavy rain and it hasn't leaked.
It did take significantly longer than the 50 seconds the manual said to aquire a fix when I first turned it on but once it was 'warmed up' it was fine. Good batteries literally last for days on end, as long as you DON'T use the back light. The back-light seems to sap them in minutes. I accidentally left my unit on in power-save mode for two days on my coffee table with a set of batteries that had already done several hours daytime use. They were 'almost' flat after all that time. Not bad.
Over-all this unit has meet all my exepectations and I recomend it for geo-caching. Got'a be the most bang-for-your-buck unit around.Get more detail about
