In the video of the St. Johns River Crappie Masters Tournament, it was mentioned by the winning team that another boat's fish finder was 'pinging' a lot and if they wanted to catch fish they better turn it off. He also mentioned that they did not turn on their fish finder all day. Does anybody know why? Some areas of Lake Woodruff are only 7 feet deep. Is that why?
The "ping" they're referring to is the sound wave pulse that the transducer puts out to reflect back the image's distance from the transducer. Fish in really shallow water and/or really spooky fish "can" be turned off from the ping "noise". But, I would think that with the number of boats with "pinging" electronics out there ... the fish would likely become used to it.Quote:

TM prop wash & noise, dropping things in the boat, the shadow of the boat (& the boat itself), your shadow & movements in the boat ... in shallow/clear water ... probably rate higher on the fish spooking reasons chart, than the ping of your depthfinder. IMHO

Thanks CP! It all makes sense.
Is it only the newer machines that have an audible ping??? Older Lowrance doesn't seem to. Brother says his Elite 5 does. With sonar off can the map still be used? Always seem to come up with 'twenty questions'.--shu
Yes.
I could hear my old HB Piranha real good. Click click click
Sounds like a bunch of crappie to me.
You can put your hand over your transducer with it on and feel the ping. Some units you can hear. some units are louder than others. You know the fish can hear it if you can feel it with your hand.Espically in shallow water.
