Depth readings - Lowrance 330C

[brucehawsker]

Well, Kevin moved the transducer, following RichardB's comments, on the basis that the paddle wheel stirred up the water.

It worked - thanks Richard.

Now I have another problem. The transducer does not stay in the deployed position when yours truely is out in Solent chop and we are going at 30 knots. Something to do with attitude, in both senses of the word.

Dare I tighten the screws on the bracket and risk losing the whole thing to an obstruction?

Cheers

Stick it inside the hull and be done with all this nonsense. Do a search to find out how.

If it's any consolation Bruce I've never had a boat that had a depth sounder that worked above 15knts!

In fact my new one doesn't either, so will try a few things suggested here.

JW - Through hull transducers are just another expense and you have to start drilling holes in the deck of your loverly shiny new boat. Something that not everyone is comfortable with.

Just glue the normal sensor in the transom well using expoxy or silicone (yes I know the manual says not to use silicone sealant but it works quite well) Lowrance are quiet powerful sounders so will fire through solid GRP. We did this to the club dive boat as a temporary measure for an afternoons diving, that was in 1996 and its still there.

I stand corrected.......sorry JW!

I thought they had to be mounted in the hull, as normally (for the boats that have them) there is a pocket made in the hull specifically for the purpose. I didn't know your could use a transom transducer to shoot through the hull, I'll give that a try if all else fails!
