Yesterday I bought a Magellan Sportstrak and man what a difference! I walk out the door and it's locking in the satelites and has it's bearings in 60 seconds. When I get in the truck and drive, it holds its bearings all the way to the cache. What a difference from my Cobra 100. If you saw my earlier post you know I was standing around 10 - 15 minutes waiting on it to lock in some satelites and it was always losing it's fix. And that's not in the woods, that's in my non-wooded front yard! It didn't get a fix at all in my truck. Needless to say I will be selling the Cobra at my next garage sale. It was a wasted $100.00.
