I have a question about the GPS units you have for sale. Can you tell me how many Geocaches can be loaded on at one time. I have a Magellan Explorist 310 now, and it only will hold 10 to 15 at a time. It also runs on 2 AA batteries and goes through them very fast. I was considering a Garmin Etrex 30. But if yours compares, I will consider one of them. Thanks in advance
