Here recently. Possibly ever since software 2.0, cant be certain on that. I now have a 3 to 4 foot depth difference between my main sounder and the dff3d. The main sounder is correct but the TZT is showing less depth. Transducer draft is the same for both at 1 ft. The issue is the DFF3D is cutting off the first few feet of the return. Instead of showing the zero line its starting at around 3 or 4 ft. I know the traditional sounder has a zero line rejection but I dont believe the DFF3D does. And dont believe that changes the depth but maybe it does. Can anyone tell me what other setting or combination of settings if any could be affecting this? Thank you
