Hello everyone, new to the forum. I started GL fishing last year with friends who bought a used boat. It came with an old LMS-350a along with a Fishhawk 840. The Fishhawk works great, but they wanted to upgrade the Sonar & GPS, so they ordered new Lowrance stuff - Globalmap 5200 C & X515c DF. What I lack in fishing knowledge I make up with mechanical aptitude helping them keep to boat in good working order, and I agreed to help install the new electronics. Does anybody have any specific do's or don'ts when doing this? Thanks.
