Hey Lawren, I use the factory Minn Kota Transducer in my Fortexx on my bow mounted HDS7. My question is I have a regular shoot thru at the back that my HDS 8 uses. If I set the front transducer to work at 83khz would that create less interference on my HDS 7 screen? It will also give me a smaller cone, but seeing as I am usually only fishing in water less than 40 feet does it (smaller cone) really make a difference? I usually just stop sonar on the structure and rear transducer when I am on the electric drop shotting etc. to avoid interference and stay quieter.
Thanks,
Colin
