Pros: Rugged, Programmable, Easy to navigate and use, easy to see in sunlight
Cons: Still looking to find something
I am not sure why others are leaving poor reviews for this GPS. I've taken mine out several times when kayaking and have fallen in love with it. It is accurate, has tons of options and informational settings and after 4 hours of use, I have yet to see the battery meter move from full (I do utilize the suspend mode whenever I can to conserve however, but this in itself is a great feature to have). The camera takes great pictures and the voice recorder is outstanding in its' clarity. So far, the accuracy is either dead-on or within the parameter that it says it is at (16 Feet, 30 Feet, etc.) If you want to take a trip and be able to download all the info to tell a story, this is the GPS to have! I've had absolutely NO problem with the touch screen. it's a resistive touchscreen, so people used to capacitive (iPhone etc) may think that it's not responsive enough. I'm old school though and this works as good or better than anything I have used before. Getting set up with it is a breeze and I tested the water resistance up to about two feet for 20 seconds. Pulled it up and took a picture and a voice memo at that waypoint. No issues whatsoever. In contrast to the others here, I believe the Magellan 510 is worth every penny.
