Ive been researching GPS receivers, and Ive narrowed it down to a few. Has anyone used a Garmin rino? Their big selling point is the combination 2-way radio, NOAA radio, and GPS receiver. Space is at a premium in a kayak, and one unit that combines three is very attractive to me. The ability to track/be tracked by other users is nice, but I doubt that I will be able to use that function very often (I dont know any other users). Anyway, my major concern with the unit is the small display size. I have never actually used a GPS receiver outside of looking at them at BPS, and I dont know how the small display size will impact use with topo maps. Even the handhelds with the largest display size are not much larger, but I dont have any experience to how much difference an inch will make. It is my understanding that large displays are important when using the GPS for car travel, but I will be using this unit solely for fishing. Any input is greatly appreciated, Thanks!
