This is a good chance tp talk about "Mix & Match" X-ducers.
What? What the heck is a "Mix & Match" X-ducer?
Most people have never heard of them...... It's a X-ducer that has a 5ft cable on it. Then there is a cable that plugs into that cable and has the proper end to hook to your Garmin, Lowarance, Furuno and God Forbid you spent money on Raymarine.
These have to be asked for specifically.....You will not find it in a catalog. I highly recommend BOE.
So......If you have one of these in say a Airmar B-164 and have Furuno electronics and now you want to sell the boat without electronic's..... And the new owner likes Garmin...... All he needs is the intermediate cable. Maybe $60?
You tape the new cable to the end of the old one up at the helm...... Pull it back thru. Unplug the Furuno intermediate cable and hook the Garmin intermediate cable up. Incidentally.....I like to add a sleeve of shrink tubing over the connection.
That connection gets pulled around and ends up inside a rigging tube a lot of times. Rigging tubes are inheartenly damp most of the time. Shrink tubing keeps moisture out.
With a "Mix & Match" You are now selling a asset with the boat if you have a 1000watt X-ducer in it.
So Next time check into this.
