This thing is really as bad as all the other reviews say it is
I purchased a GPS500 for geocaching, mainly attracted by the low price and "FAST" acquistion feature. Screen resolution is terrible, acquisition times vary from 6 minutes to never, accuracy (compared to friends' GPS units) was way off, and it proved to be utterly unreliable in the field. I returned mine 10 days after I bought it and got a Garmin eTrex Legend. I am now quite pleased.



Paper weight
First day I got it, it had trouble connecting. Second day, it wouldnt turn on anymore. I dont understand how a company can sell something of such poor quality.



Cobra gps500 a toy
Recently upgraded a cobra 100 for a 500... first time out, it failed, leaving me in the woods all night 'till I got a bearing on the sun in AM... When they say take a compass with you, they mean use your compass and leave the gps in the car!!!
The unit looks nice, and works well enough as long as there are no trees, clouds or perhaps birds flying above you.
It's great as a childs toy, or to find the parking lot where you left your car (but not the car itself) $5.00 for a compass and twenty cases of beer, or a gps500, for about the same price... It's your choice!!!



One Star is Too Good a Rating!
Repeating the sentiment of the earlier reviews? Yes, I am. Important to do so? I'd say, yes, it is, since you might think the other three reviewers were just unlucky.

The Cobra 500 is absolutely useless. It locks onto the required 3 satellites ... sometimes. Usually not. But when it does lock on, it loses them within a couple of minutes. On the other hand, when you look at all the features listed in their literature and compare it to the modest price, you think it's too good to be true. Unfortunately, it is. Truly a P.O.S.



Nothing comes close to a COBRA! Don't you!
I purchased (through the Air Miles rewards program) the COBRA GPS500, not once, but TWICE. I first purchased the unit and believed it to be faulty it performed so poorly. Signal acquisition time seemed "forever" and it frequently lost satellite lock. On several occasions, between establishing lock, loosing lock and again re-establishing lock, the unit tells me I've moved upwards to one half mile whereas I've remained stationary, only changing the direction the unit was pointing. Simply changing the direction the unit was pointing (like changing direction in your car or boat) was enough to loose satellite lock! Very poor! I was able to exchange the original unit (unfortunately NOT able to return it) and when I received the replacement unit, it, like the first one, performs very, very poorly. The features offered on the unit would led you to believe it would "shine in the dark," whereas in actual fact, it is the poorest of any GPS unit I've ever used. And to add insult to injury, while I was awaiting deliver of this second unit, believing the first one faulty, I wasted an additional $100.00 by purchasing the PC interface cable, power cord and auto mount. What is that COBRA slogan: "Nothing comes close to a COBRA" You better believe it! Not even a satellite signal is able to get close!
