West Basin,

We have had zero negative issues with our Blue Tooth Fish Hawk. We get a full season out of one set of batteries (4 AA).
The best part is it integrates with our Solix and Optimas. I haven't figured out how to get it to control the Ultera yet.

I can't imagine trolling without it!

We now know depth, speed, and temp at our baits. It is amazing how far off the GPS speed can be. We use the temp feature allot in the early Spring and late Fall, can be very different than surface temp, and helps find the active from inactive fish on the graph.
