Rickie ive got a 2d trans already being used on this unit for higher speed but with a switch not the AS SIDB Y cable , now with what kosmo says about the 3 other units being needed , Im going to have to skip this idea , 3 more units I'd rather buy a bigger boat lol. Thanks again for all the info. Thanks for the detailed drawing of how the ducer works.
Why are you using a switch for the high speed 2d "shoot thru" instead of the AS SIDB Y cable ...??
