Larry M -

The AIRMAR B744V transducer is dual frequency (50HZ & 200HZ). I have often switched between frequencies when striping occurs and it makes no difference - i.e. striping remains present. Depth does not seem to be a difference maker either. I feel pretty confident that it is most likely a EMI problem and I will need to find where the transducer cable goes.

Thanks,
Bob
