Second Fish Finder w/ Narrow Beam, How to?

Default Second Fish Finder w/ Narrow Beam, How to?

Please help on my fishfinder situation if you can.

I'm currently running a Raymarine e120 hooked through a DSM 300 to a Airmar B60 transducer.

That combo gives me cone angles of 45 degrees at 50 KHZ and 12 degrees at 200 Khz. Not bad for trolling the stream and fishing structure in shallower ocean water. But I also want a narrower beam unit as well fo deeper structure up to 200 feet!!!!

So, I'd like to add another 200 khz sounder at 1KW with another transducer that has a narrower beam for more precisely locating structure and bottom fish in water from 80 to 200 feet deep. For that purpose, I'd like to have a 200 KHz ducer with a cone angle of about 6 degrees, so I'm considering a Airmar M260 because of installation ease. (But I don't really need another 50 Khz ducer.) Yeah the hull is not cored and I can shoot through just fine.

The situation is that I'd like to be able to run my E120 with the 200Khz at 200 Khz and my seond unit at say 180 KHz. .....So I can see both screens without terrible 'ducer interferance.

I'd like to run a Garmin as my second unit but I don't think the GSD 22 with a 4210 or 4208 would allow me to set the transducer frequency at say 180 Khz. OR WOULD IT?

I'd also consider the new Airmar SS264N-200 as my second transducer if necessary.

I'd really appreciate any help or advice from the pros about this.

Hopefully you get the gist of what I'm wanting to accomplish.
