I have an approx 10 year old lowrance lms-522c . I believe the depthfinder is good and the transducer is bad. I purchased a 106-89(aka prdt-wbl) online. the package says LEI ACCESSORIES but I think it is genuine lowrance .the cable doesn't fit the
depthfinder . the nut at the end of the cable is very slightly too small. any idea where I went wrong ? also , I am in the market for a transducer .
thanks

Should use a 106-72.

This should help.
