Topic: what transducer to use

[Howie]

I would like to use a second transducer mounted in the bilge for my 898. Which one do I use?

I am assuming that this is for high-speed 2D sonar readings:
XP-9-20 transducer and an AS-Si-DB-Y cable.

Greg what model would we want for 2d readings off of the transom?
