Has anyone here used the XI 9 20 Ice ducer from Humminbird with their 798ci HD si head unit? it isn’t listed as a compatible model for the ducer. I have read on other forums that people purchased the ducer for this same model, but there were no results as to whether or not it worked.
I have used the XI9-20 for one full winter last season on my 798 HD SI and haven’t encountered any issues with using that iceducer. You will need to shut off your simulation mode in the unit so that it will recognize the transducer. When I set mine up I also bought a 9AH battery so that I could have enough power for extended days fishing. I love this unit on the ice. Lake master maps are great to have along! The only drawback is that the power and sensitivity can be a little too much in very shallow water. IE 10ft and shallower. HB had an update this past march though that addresses the shallow water read issue. I noticed a difference in the boat. I am hoping that it also works better on shallow water ice fishing. Good luck with your unit!!
