Re: Garmin ChartPlotter Confusion

I was just gifted a GPSmap 188C Sounder with no cables, transducer or antenna which is my first exposure to this so I am new to all this myself. I am not sure the used 188C will be worth the cost of the dual frequency transducer, antenna and cabling even though I see them still selling for over $400.

Been a shallow draft (less than a foot) row and power boater on a shoestring for 50 years so working on sailboats in the boat yard the past few months has been an eye opener. Even a picnic boat draws 3' 7" with the center board down which leaves me highly constrained compared to the freedom of the shallow draft I was used to allowing passage in 4 to 6 inches of water so I really see the need for sounders and such on sailboats.
