transducer mounting

[995jim]

Hi, im looking for a transducer that mounts in the hull rather than outside on stern. Are there such available?
thanks jim

I think so - but it may be like "kissing through a screen"
certainly, devices and electronics improve all the time
likely depends what you want your transducer to do

In hull or thru hull several companies make them

Many thru-hull transducers. They get glued to the hull on the inside. Been around for almost as long as fish finders been around

Does not work well with aluminum hulls, but do fine on glass hulls.

There are all sorts. If you have an aluminum boat you can mount one by drilling a hole through the bottom of your rig and fitting the transducer inside the hole. These come in brass, stainless and some sort of plastic. you will have to pick the one that will not cause corrosion in your environment. They come in flat 10 and 20 degree angles so they can be mounted on the angle of your boat and still go straight down and not sideways. For fiberglass bottoms it is a bit different. Fiberglass has the same reading as water. That means that you can just glue a transducer onto the bottom or have it in a small water reservoir in the bottom of your boat. There is also a type where you drill a small hole in the bottom of your boat and slide the transducer shaft through it. while you have a faring block on the outside that makes it sit on the desired angle.
These setups are not great for boats that are trailered a lot because loading and unloading can damage the transducer that sticks out.
If you want to find out more you should go to Airmar website. They make 99% of all transducers in this country.

Thousands of bass tracker boats would say otherwise

i have fiberglass, thanks everyone

Shooting thru an aluminum hull ? According to my local BP shop, they have never shot thru an aluminum hull except for depth reading only!!

In-hull installations work well for depth readings, but you loose a lot of target sensitivity in the process.

If sonar performance counts.....a "glued on hull" installation isn't going to cut it.

50/200 Puck AlumaDucer w/Universal Connector - 25'

The AlumaDucer is the world's only depth finder / fish finder transducer designed to transmit through Aluminum with ZERO signal loss. The revolutionary new AlumaDucer is built using a universal transducer connector. Along with the proper adaptor, you can fit it to almost any 200 kHz, 80/200 kHz...

Both the 1984 Bass Tracker III and 1991 Tournament TX in the family had glued in transducers

The Alumaducers are known for very poor performance. If they were any good, they would also be made by Airmar and Airmar does not want to touch them.

Can’t over come the physics of sonar detection. The resonance of the aluminum hull is “blinding” to an acoustic device.

At one time, Airmar published acoustic data for a shoot thru install in a fiberglass hull. Showed just how much signal degradation took place with an in-hull installation. Turned out the biggest factor was the thickness of the hull in relative to the wave length of the signal, not the overall thickness of the hull

As I noted above, if your idea of “working” is some sort of a depth reading, then go for it

Yes, many mfgrs tried it on aluminum hulls, but you see very few today and the few you do see do not work well
