most basic aviation GPS for backup work
I am looking to buy a very basic (i.e. inexpensive), simple aviation-able GPS to have with me as a backup to pilotage, dead reckoning, and radio navigation. Does anybody have any suggestions on such a unit? It can be as simple as to just give me a heading to a waypoint (say, my home-base airport) and a distance, or even just an arrow that points toward the waypoint. The only stipulation is that it has to work (get good reception) and be reliable (understanding that it will not be as reliable as an IFR certified GPS unit). Hoping to get some good suggestions. Thanks guys/gals!
