I just purchased a new Lowrance HDS-5 and my speed shows up on the chart screen but reads 0.0 on my sonar page. I,m new to the site and would greatly appreciate any assistance. Thanks in advance
I am not a Lowrance owner. One possibility is the speed on the sonar screen is for a paddlewheel and not gps. I would have thought it would default to gps, but go through you set-up and configuration screens. Otherwise, look to see if Lowrance has new firmware to load in the unit.
