so i have the setup of the HDSI transducer and the xnt 9 20 (to have depth reading at speed) with tye Y cable.
I installed it and went today to the lake, and it works. but sometimes it goes crazy and i start getting reading of 1151 feet or 800 feet, i noticed this while the boat is not moving. while the boat moves i think i didnt have any issue and i had some readings going at speeds of 20 to 30 mph...
what could it be?
some transducer interference ?
i have something really close to this setup...
