Peter,
I often fish smallish structure submerged in the middle of bigger water, so I need to have both units easily visible to monitor my progress. I also fish alone often so between navigating and fly fishing, I prefer to be able to quickly see pertinent information. That led me to get 2 units, both color. I opted for the Gamin 320C and 182C due to their reliability and excellent full sun readable displays.
