Thread: HB 858C DI problem-help

Stickman,
You could try connecting your 858c DI unit up to your 998’s transducer (not the other way around) for testing just to see if the problem is in the unit or the transducer. It won’t be perfect but you should be able to get 2D sonar and DI sonar readings - be sure and have the “Beam Select” menu on the “200kHz” setting so the 2D sonar will work.

Forgot to mention that you will need to change the “Connected Transducer” menu to the “DI 200/83” menu setting for the above test.
