Which transducer do you prefer? Thru the hull or on back of the transom. I have a humming bird 700 series.
I used to always use thru the hull transducer because it was neater and cleaner, and I would not have to worry about damage to the xducer. Now I choose to use an external transducer so that I have the best signal possible without having to shoot thru hull. I feel that you loose a little bit of the signal when you use a thru hull transducer.
Thanks Wayne, I hope this helps.
