[cool] Good quality sonar systems are pretty water tight. The display unit is lashed on top of the tube, and the transducer may be attached to a piece of PVC pipe or wood, depending upon the type of unit. I have pics and diagrams when you get to that stage.
Let's just say that if your sonar system is in jeopardy, your body and the rest of your tackle is going to suffer too...as in being totally submerged. If you take care with your sonar, and don't bang it against hard objects, it will maintain it's watertight integrity.
Only when you shorten the transducer cord...as I do...is there a risk of water penetration. You have to cut and splice the cable to shorten it...using solder, shrink tubing and/or waterproof silicone. Still, you should never have to worry about the splice being below the water...unless you overturn or get blasted by a giant wave. If in doubt, don't cut and splice the cord...especially if you are also going to use it on your boat...or maybe sell it to someone else some day. Just roll up the extra and tie it in a ball.
