The PAs are the best fishing platform ever built. I cast about half the time for warm water species, bass, walleyes, perch, crappie, etc. The rst of the time I troll, one rod in rod holder, the other in my right hand for quick response.
My left is on the steering handle, usually full time, making small corrections. It is like steering a small plane, Do not over correct, and give it time to react. Also, watch the top of the water ahead. Lots of times you can "read" the wind incoming or quartering.The wind is not consistent, it has holes and eddies just like water. Anticipate. If you are rounding a corner as an example, your wind will be different. Also, a tail wind is more difficult to judge than an incoming. Much easier to steer into the wind.
Also, don't over pump your drive unit. Use only enough force to make your PA respond to what you want. The more you use your unit, the more instinctive it becomes, a combination of thrust and steering, but mainly, anticipation.
I have used about every type of rod holder, but really like my current units, Cabelas Quick Draw. They make more sense when you have them in hand then trying to explain, but they allow you to lift the rod straight back, then up, which keeps the line to the fish taut. Super idea, simple, and it works.
