My crew and I are tired of the blinking depth sounder number when we are shrimping. Our boats have the newest sounders and mine actually was just installed last year because of the annoyance of the previous one! We usually idle our motors and sometimes shut them off and they still do it while we set our shrimp pots. We work the same area over and over, so fortunately we don't need to rely on them, but even in the calmest seas they still lock in a number and just blink. No, it's not motor cavitation bubbles, not waves, no shrimp lines or pots, depth maybe. We spend plenty of time around the research and development campfire pondering this annoyance, what do you guys think???
