I have to replace my depth/temp transducer for my vesselview. My lake marina said they prefer to pull boat to replace. However I have the dummy plug but maybe they just don’t want to take risk of something going wrong when they pull transducer. Idk. Nothing wrong with trying to save $375 on a boat pull if it isn’t necessary Any thoughts ? Also does anyone know which transducer would work with my vesselview? Here is the pic of the unit I have. They are made by Airmar? Thanks!
