The first thing, go into your sonar setting and select the correct transducer that you're using, there should be a silver tag on the cable with the model number, if you don't have it selected right you're only getting about half the power. Select the correct transducer and click SAVE. Then I'm sonar setting if fishing under 50' of water select shallow water, if deeper then keep it in general. With an 83/200 or 50/200, set to 200 if fishing shallow or when running, 83 or 50 in deeper water You can play around with ping and dial it in while your out there, I think 18 is where I had mine. But once it's tuned right you should be about to get great returns Sent from my iPhone using Lake Ontario United mobile app
