Default Fish finder sonar recommendations for Puget Sound

My 30' fly bridge trawler has a Raymarine depth sounder but no electronic fish finder. I am plan to upgrade the current electronics and want to include fish finder sonar. We cruise the vessel primarily Olympia to Seattle. My grandson is an avid fisherman; I am not. Any advice will be appreciated.
Thanks

Precisely which Raymarine depth sounder do you have, and how would a fish finder sonar differ?

Raymarine ST60. It works well as a depth sounder but is unable to find fish. The newer sonar units are more powerful and designed as fish finders. Thanks for your post.

Which of the Raymarine "instrument" transducers is connected to the ST60 instrument display, and what type of connector does it have? You may have a transducer which is compatible (with or without an adapter) with any one or more of the available Raymarine fishfinders. If so, that would simplify things greatly and save money too. I would send a PM to THT member CME. He is very knowledgable and up to date on all things Raymarine.

In Puget Sound, where you would be fishing salmon and halibut primarily, I would recommend an SS175C HW.
It gives you a 25 degree view and 1kw of volume is plenty for solid target separation down to 600'.

The depth transducer is an Airmar B-45 (200kHz-U) mounted thru the hull on the port side.

The B45 should have dual 200/50 kHz abilities when matched to a suitable fish finder. Using it for that purpose depends upon the ability to make the appropriate connections. If you post your question over on the Marine Electronics forum, you'll quickly receive better advice than I can give you. Hopefully, a new Raymarine MFD is in your future and you can hook it up to your existing transducer.
