LRF - LIECA.

GPS - I like garmins I have owned 4 now (base model etrex, summit andcurrently have a Nuvi in the wife's ride, while I upgraded to the Map60CSx). All have provided good service and no troubles or repairs needed.

In terms of the Rhino systemif others inyour party/group use rhino's then they are nice due to the radio/beaming functions. If not thenI see little need or reasoning to buy a rhino.

Good luck
