I personally would go with a through hull transducer and go with the one that will give you the whitest angle from top to bottom. Like a B744 or B60 both are true work horse. Just my opinion.
I would suggest getting ahold of Yankee troller on here Richard will steer you in the right direction and probably get you a good deal on a transducer.
I have a brand new FishHawk X4D for sale never been used. Also comes with a optional cover. Only reason I’m selling is I’m going in a different direction.
Asking $1000.00
will ship on buyers dime.
