[CA] transducer selection

Might you be able to assist with the proper selection of a digital transducer for a 45 foot sail boat FRP hull. I was hoping to use a triducer DST and connect into a STng network. I see the A22154 with a wide cone and the A22111. I am planning to use an I70 I60 P70 and E97..

perhaps you can steer me in the right direction

thanks as always

David
