RE: incorrect depth when fast

Hello r0ckteacher,

The cause will be either air under the transducer, or high background noise. Boats are noisy places at speed, some noisier than others, and if the sounder can't here the bottom echo amongst the noise then you get no bottom trace and the sounder goes into Bottom Search Mode and ranges right out. There's a lot of information about the causes and how to diagnose these problems on this FAQ. Feel free to take screenshots and post them back here for us to have a look.

Regards,
Tom
