Best transducer to use for NaviSounds ‘over the side’ / outboard rig mounts

What is the best transducer to use for NaviSounds ‘over the side’ / outboard rig mounts?

Most customers will want a 33kHz / 200kHz dual frequency transducer, for over the side mounts go for the ‘fishy’ transducer: TC2178 with integrated mounting plate. Go to the TC2178 product page on reson.com

(Don’t worry, there is nothing fishy about the transducer except for the shape).
