You guys have all the answers, so i am asking. I have a X 510c which has the same transducers as the HDS 5x . Can I just change out the unit head. My question is will the same power cord work with the hds 5x. If I later go to structure scan will I then have to change out the power cord. I have asked this questions to various sorces and have gotten different answers. This would save me from pulling the deck again. .....Thanks for any input, I love reading everyones comments.
