There Was just a touch of current, I did try to play with drilling a hole a few feet up current for the transducer.
Chirp I didn’t try much, I thought chirp was a under 40’ thing. I obviously could have been wrong about that, I’ll try more.
I don’t like I have “TVH” where would that be?

I’ll definitely try it again and play with the transducer more. Thanks for the advice.
