Re: Garmin GPSmap 451s and Raymarine Sounder
You 'should' be able to use both sounders at the same time.
I have a Lowrance unit with 50 / 200 sounder and an old Datamarine depth finder as well. when I first installed the Lowrance unit and turned it on, the Datamarine unit would blink 0 once a second or so. When I set my Lowrance unit to use the transducer on 50 hz only, the datamarine unit would work fine.
So see if you can set one unit to work at 50 hz and the other to work at 200 hz.
