I recently bought a Lowrance LCX 38 for a 21' Nitro.  Should I mount the transducer on the rear of the boat or do a shoot through hull install?  How do you have your electronics set up?

Rear of the boat  

If you fish alot of lakes with stumps, stickups, and underwater obstructions, the thru hull puck is the way to go. The 38c has plenty of power to shoot through the hull without any resolution loss. I have the 27c and have great picture.

You never have to worry about getting it knocked off.

By the way, almost forgot.    Welcome to the forum.

Great site with great peeps.

Rather than make a smart-azzed reply, I would suggest the you go to www.lowrance.com and read their sonar tutorial.

BTW, your question is going to get moved to another board on this site.  How quickly it will happen depends on how many of the mods are still awake and sober.  

Mine is thru hull.  Cut a hole in a forward storage compartment and mounted it and put a cover over the hole for easy access.  Nothing external to get knocked off/loose on stumps or rocks.  No problems after 3 years.

Not knowing how your boat is set up now but assuming you don't have a unit on the console mount the display on the console and the transducer shooting through hull over the pad. This will give you a better shot for display at speed and the only possible display on plane.

If you don't have a front deck unit you won't know where you are in regards to structure, depth or cover when fishing. Absent a front deck unit you ,ight want to think about a second unit with the transducer mounted on the TM.

There are ways to network sounders but I don't have a clue as to the how's and why's.

Welcome and good luck.
