I am about to order me a Lowrance 520 but i cant decide whether to get a transom mount of shoot thru tranducer with it.. the garman i have on my triton right now has the shoot thru , which i like not having wire running down the transom... but on the other hand i want the best performance out of this unit.... anybody got any good advice or knowledge on the subject....
 
I have a 520c and i monted mine on the transom because a friend of mine monted his in the hull and didnt like it. He ordered another transducer and monted on his transom. He said it doesnt have as much cluter on it now. So i took his advice and monted mine on the tansom. I think the transducer that the unit comes with will do either shoot through the hull or mont on transom. Hopr this helps some.
 
if you get thru hull mounted up right you can just forget about it forever....thru hull gives you 0 turbulence since it is in a area of solid water under the hull. Anywhere behind the transom is subject to air and uncertain water plus the possibility of damage . Not to say it won`t work on the transom , I just prefer not to worry about it.
Maybe I just got lucky but I`ve had zero clutter probs with mine. It tracks exactly like the x-70 on the trolling motor and works great at speed. You have to make sure you get it right before you glue it down.
 
all transducers can shoot thru hull ( ONLY in a FIBERGLASS BOAT ) , there are advantages and disadvantages with both ways, biggest advantage to shoot thru hull is high speed, if your boat is fast enuff it will rise up out of the water, and only a small portion of your hull pad will be in water .. and your transducer is out of the water at that point if mounted to the outside of your transom.
Also prop wash will mess up signal, and give you false readings. not to mention your putting holes in your transom and allowing water another way to enter the wood in your transom, unless you are lucky enuff to have one of the newer all composite boats that have no wood.


Mounted inside shooting tru hull takes care of those 3 probs.. and you may loose a slight amount of signal , but the benefits in my opinion out way the the slight possible signal loss.
The biggest prob with mounting to shoot thru hull .. finding a place in your boat on the rear pad that is accessible and is thin enuff to read thru hull. You will need to mount by setting the transducer in a bed of epoxy and that epoxy has to be bubble free, or make a water box to sit you transducer in here a link on how to make a water box and other solutions for thru hull mounting http://www.tritonclass.org/mir/TRANSDUCERS.htm

I would at least use a water box to find a location in your boat to mount the transducer before epoxy to hull.

I only used mine to find structure and depth while underway.. while fishing mine is mounted to trolling motor on a separate LCR

Does this mean you can,t shoot through a aluminum hull boat???emoScratch emoScratch

A transducer cannot shoot through wood or metal hulls. Those hulls require either a transom mount or bolt-thru-hull installation.

If your Skimmer transducer has a built in temp sensor, and you mount it shoot-thru-hull, it will only show the temp of the bilge, not the water surface temp.
Loss of power is between 5 to 50% in shoot thru hull installations.
Once installed, the shoot-thru-hull transducer cannot be adjusted for the best fish arches.
 
You can get a transducer that is actually goes thru hull too .. a hole is drilled and the transducer sticks out of the bottom of boat ... usually a bronze transducer .. and not a recommended DIY project. This will work on wood , metal, or glass boats

I think those are called bolt-thru-hull.
