I have a Furuno FCV1100, and I just purchased an Airmar SS270W transducer in an effort to cover more bottom area as both 50 and 200 kHz freq's have a wide 25 degree beam width. I want to confirm that the plug should go to the High freq side on the unit and would like to have some feedback on settings, to get the best performance from this transducer/sounder combination. I bottom fish, wrecks and natural reefs from 80' to 300'. I lost several of my own home made wrecks during the hurricanes we have experienced in Florida over the past years. I want to stretch out as far away from the boat as possible in an attempt to relocate these places. Any help regarding this matter will be greatly appreciated!
