I buy this gp about 3 month ago and it have perform well in all aspect . now I buy this gp with the primary purpose of hiking , biking , and geocaching -lrb- I have a separate gp for the car -rrb- . if you be look for a gp to use in the car ... there be better one , this one will not call out direction such as `` turn leave in 400 ft on 5th street '' like other model will . it will do road direction , but it will only give audio beep que . if you want you gp to do the outdoors-type of stuff that I do , you probably can not find one that be better . I see a comment about it run down battery too quickly when I be shop and be concern , but because 2 friend of mine have and love this model , I take the plunge . I have have no battery issue . I use nickel-metal-hydride rechargable in it and they work great . I would also recommend that you read the instruction manual . when I first start use it , it would point the wrong direction ... it be really wierd , I think it be break . then I read the instruction manual and realize that I need to calibrate the compass . the simple procedure take all of 15 seconds , and everything be correct . aside from this , this model have a ton of functionality , I have spend hour go through all of the feature and probably could have save a lot of time by read the manual . overall , as I say earlier , this be a superb product .
