Transducer advice.

I need some thoughts from anyone in the know please....!?!?

On the rib that I have just bought, whilst fettling and fiddling around yesterday, I found out, that the transducer, which is a transom type, sat inside the hull, about a foot from the stern, behind the bilge pump.

Is there a big difference between through hull type ones and transom mount ones? When I sea trialed the rib, it was giving a depth reading, but how accurate is hard to tell.

There's no problem with a transom type transducer shooting through a fibre glass or even aluminium hull as long as its bonded to the deck without any air bubbles in the adhesive or trying to shoot through a double skinned hull with an air void. The only thing that will not work correctly is the water temperature gauge due to lack of direct contact.

Ok, thanks for that.!

I am not bothered about the temp, as I know from diving, that the water is bloody cold.........

usually the shoot through has an angle on it to accommodate the hull angle to set the cone angle at 90 degrees to give true readings
