A CRUNCHED TRANSDUCER?
Last month we scraped the bottom clean of barnacles, and now with the boat back in the water, the depthsounder no longer works. It won’t even turn on. Any ideas? T. Talbert, Havre de Grace, MD

Carefully scraping off sea growth on a transducer face would not cause your sounder to just quit completely, so what you need to do is get out your voltmeter and check for 12 volts DC at the input plug or nearby power terminals. After that, check the fuse. Be warned, the transducer experts at Airmar tell me that light cleaning of the transducer face is good, but pounding those sea creatures off with a chisel might disrupt the phased-array transducer faces if a gouge occurs. Still, for the equipment to not even turn on, something else is clearly at work. Again, time to break out the voltmeter and make sure you have a good 12 volts getting through.
