[CA] [CA11] Hyper Vision HV-100 transducer interference

[Chuck - Raymarine - Moderator]

sdwiggi,

Our testing with trolling motors did not yield any similar findings. That said, while a trolling motor mount is offered for the HV-100 transducer, I would typically only recommend the Fishfinder application's Sonar channel be used with this transducer when mounted to a trolling motor. The reason for this recommendation is that rotation of the trolling motor will not be compensated for within RealVision, DownVision, and SideVision sonar processing. The resulting imaging would be adversely affected by such rotation. That said, the noise reported may be resulting from an electrically noisy trolling motor or from turbulence caused by the prop. To fault isolate the issue, try lifting the trolling motor slightly out of the water, command the trolling motor to propel the boat, and watch the fishfinder image. While it would be expected that the fishfinder will not plot a bottom when tested in this manner, a noisy trolling motor should still produce a noisy fishfinder image. If so, then it would be recommended that the trolling motor manufacturer be contacted regarding the electrical noise produced by the trolling motor.
