PROBLEM - This unit will not display fish or fish arcs in 2D on any setting…
I have tried 83 only, 200 only and 83/200 combined modes, various sensitivities, fish id on and off, id sensitivities, clear mode and max mode. I have reset all setting to factory and started adjustments from there several times I do not see arcs and/or fish. The 2D is showing trees and structure on the bottom and shows the thermocline but not arcs or fish.
The DI/SI mode display works correctly and I do see white marks and clouds that I believe are fish and baitfish. (I have also caught many fish close to and under the boat while using this, so I know they are there) This is the only unit on my boat and the standard GPS is the only accessories.
I have had this issue since the day I bought this. It sent the unit and transducer back to Hummingbird for service and the returned it to me saying nothing was wrong and they included printouts showing Fish.
Used only in fresh water lakes and rivers less than 40 feet deep, speeds of 5mph or less.
898C HD SI Combo - Transducer XHS-9-HDSI-180-T.
Unit shipped with ver 6.640 and I had the factory reset it and returned with 6.490, due to issues I had read about on this and other forums. That did not help so I am now running the newest Now Version 7.510
This unit is great for finding rocks, trees, terrain, and Man Overboard. Everything but Fish!
Any ideas welcome.
