pick your brain
« on: February 04, 2011, 10:17:52 AM »
I'm building a plywood fiberglass boat. i would like to use my 798 on this and a few other boats(six so far), I have the mounts and the power cables but for this application I would like to do a transducer in the hull. i know side imaging is out unless i go thru the hull, so 2-D is OK, but i know it is not good to shoot thru the wood. Does any one know how to do this. My reasoning for shoot thru is because i expect this boat to spend a good amount of time grounded on my rocky beach or on the trailer, knowing a transom mount or a thru the hull might break or crack due to the boat rising or falling with the tide. Any thoughts on this?[.ila_renderedila_rendered

Hello Babarosa,

have you ever thought about a telescopic mount?
I had my transducer mounted like that two years ago and it worked very well. Here's something I wrote about it and Hendrik dropped in with some good ideas as well:

This might work for your boat and surroundings too.

After I had the under water part of my hull renovated (and cut off the stabilizer) last winter, I have the transducer mounted now without the telescope. If you need it, it's still somewhere in my shop here and I would send it to you if neccessary.

Good luck and best wishes / Harry

My thoughts exactly Harry.  Perfect scenario for this application.

You are just not going to get decent if any side imaging from mounting it in the hull, especially a wood hull.  If it was fiberglass, you may be able to get some decent results, but its hard to get the right position so you get good left and right SI.  The transducer has to be level since the SI elements are on the side of the transdcuer at an angle.

I would certainly look at some of the images in the gallery.  There are several guys here who have built telescoping mounts.

Good Luck,

There are several manufactures that make the types of units.  I will look for the links (again).  I think there is one posted here ( in the forum) some where also..

I had the same problem whit my boat as babarosa have. No good place to put the transducer. So the only place to put it was in the front. It as also be fixed so it is easy to take of when risk to hit a rock is big.

So I made a temporary aluminium pipe in the front of the boat. Se my pics
This temporary thing has now been used  for over 2years and 120 h. And still working!

thanks folks, like the ideas, keep them coming. so far the  telescoping seems the most feasible.has any one done one that could be rotated 180 degrees

Look at some of the pictures and then think about making your own.  That way you can have it do what you want it to do..
Raise or lower to your selected depth or turn 180 degrees. 
You can make a telescopic rod fairly easily and of course the bracket Johnny Ray will let you mount the transducer very nicely.
Look at this site for some ideas and hardware.
