I gotta hole in my hull !

[29cascadefixer]

Hey Guys and Guyettes. I have this hole in my hull where the transducer for the depth sounder used to exist. The transducer corroded at the wires entrance point, an so, the depth sounder also being old, I decided to bring the equipment up to date. I am trying to make a decision on the type of sounder to get. I like the Raymarine ST-40 and the Uniden 206. I like the idea of the Uniden of being wireless so I wouldn't have to string another cord through the boat, but I wonder about the Unidens susceptability to outside radio waves, electrical interference, etc. Any of you more experienced sailors out there have any input for a supplicant.

I'm a big wireless fan but you still have to run 12 volt power lines to the transducer. Running wires and the problems they cause are not a free lunch either.

The technology isn't all that different as far as measuing depth goes so picking one over the other may be best answered by the size of the hole you have in the boat and which unit fits best.

After that sometimes it really is all about the money. On eBay you can get the Uniden for about $75 give or take plus shipping.
The Raymarine ST60 is about $350

I prefer an in-hull, rather than a through hull for the echo sounder. The only reason for going through hull is either cause the boat material is unsuitable for a in-hull, or you want a forward looking system.

Finding a transducer the same size as the hole maybe the biggest challange.

The old sailboat transducers were a lot bigger then the new hi-tech unites of today..............._/)
