I have a Magellan Triton 400. I think I have done my homework on how to use this device and find my first geocache. I have tried three times, each with no luck. I drive and park at a location that I think should be within .5 miles of the cache. And each time my GPS unit shows the cache to be much further away. This has varied from 1 to 32 miles. In the case of the cache that was within one mile, based on the description I was very sure it was in this park along a paved path. But my GPS showed the cache still 1 mile away which would have been in someones backyard.
How can I be sure my GPS is functioning properly? I am tempted to return it and get another model or different unit.
