Guy, I am having a Strange problem with my 1198c 2d/depth reading. SI is working fine with HDSI.
When the boat speed is below 10 km, depth reading is fine but not in high speed. Because of the console space limitation, my 1198 is very close to( almost on top of the Speedometer). Once i increase the boat speed beyond 10km, the depth reading get mess up with random readings.
My questions is will the Speedometer cause interference with the 1198 depth readings when it start show the boat speed?
I have installed HDSI +XNT-20-9 with the same result.
The new xp-20-9 in hull transducer will cure & ready by Thursday
