What is the best solar panel and why?
I won't say it is the best, but I use the Garmin Oregon 550. I like the touch screen and having an easy to read map. it has survived over 100 river days including 18 down the Grand Canyon and still keeps on kicking. It is battery heavy though, I go through two AA a day. I try and use rechargeable, but they drain a little faster.
I picked one up after my first trip down the North Fork of the John Day. The most recent mile by mile guide was from the early 90s. We were floating along on the first day and passed an A frame house. On the map the A frame house was at mile 10 and we were planning to go to mile 12-13, so we figured we were flying down the river and stopped at the next good camp. Little did we know that a second A frame house had been constructed in the past 20 years around mile 6. We had to make up with a really long day to get back on track... Most of the time it is just a fun toy to figure out speed on the river, but on occasion it is nice for settling were we are on the river and if we should take the current camp or move on to the next camp and it works a little better than the counting creek method of navigation.20 years on the water and still have no clue why someone would need a GPS.
The takeout is...... Downstream
