Magellan eXplorist 100

I have used this unit for many years. Sailing, bike riding, as even as the GPS for a car sat nav using an old palm Tungsten T3.

It's never missed a beat. Rechargeable batteries are a must, as it does chew some juice (2 x AA every 6 hours or so).

It's a little clunky to get data off - need a 3rd part cable, and some software like GPSbabel - but it's been a solid performer, quite accurate, and it just keeps on going.

Some other more expensive models do have some pretty neat features, but you pay $$$ for them....

Solid, easy to use, and a good price.

This bare-bones GPS is all I really need. It has no mapping and does not remember anything but waypoints (without altitude readings), but use this in conjunction with a topo and what more could you want or need? Great for geo-caching. It is waterproof and tough, and not very heavy. The battery life is quite good also, a benefit of not having a map feature. Looking back, however, I should have paid the 30 or 40 more to get a mapping 200 model.
