School of fish going 3.5 with the console unit. Note how they stratify away from the boat in shallow water. Also note how many fish are in the water column.
Image from the trolling motor… What side of the boat are you going to fish out of?
Is it perfect, is it even close? Nope. Does it tell you valuable information? absolutely.. Personally, I think its a beautiful shot.
As a jig and plug pitcher primarily, this tool is well worth the effort.
If you are a live bait troller, or a plug troller or even a verticle jigger where most of your action occurs behind or beside the boat, this will probably have little value to you. If you are a pitcher, Id look into it.
Fish can be seen at speed higher than optimum (3.5) also. Heres a shot at 10.1.
You cannot see fish at 39
