I have an LMS 522 Lowrance Fish finder and GPS. I noticed on Saturday the transducer was broke where it goes in the clamp to hold it in place outside of the boat,not sure if I can drill another hole in it or not. Water is to cold to get in..lol. My question is, can you replace just the transducer or do you have to replace the unit as well. I kinda like that unit. Thanks in advance
