Variety is the spice of life. I began the GPSR life hiking/backpacking. Then found Geocaching in a magazine on an airplane. Mounted the device in the car then on the motorcycle. This was a Magellan Map 300 waterproof handheld. It eventually died with parts rattling around inside. It was with me for several good years. Next I moved up to a Garmin Quest. The prime criteria were waterproof, internal batteries, and auto routing. It works well for the motorcycle, car, boat, backpacking/hiking and geocaching. The autorouting is wonderful. Geocaching use is good but not great. I miss the foot by foot readout. Everything is a compromise. I'm ready for phase three but finding a GPSR to do it all gets harder and harder. Too many models.
