Yup, bought Hook 2 5 inch with triple shot transducer… worked fine for 4 months in salt water kayaking then my battery got corroded and broke a pin so had to get a new nocqua battery. They then recommended putting the dielectric grease on all my fittings and battery fittings. Now the transducer plug will not stay fully connected.l to the fish finder. Tried rubbing alcohol and a needle to clean out each of the pin holes but still will not make a tight connection (unless I hold it with a lot of force… ) any ideas???
