I assume you're talking about a transom mount transducer. Best if the leading edge of the transducer is even/level with the hull and tilts slightly down in the back or trailing edge of the transducer. Also try to eliminate a gap between the leading edge of the transducer and the hull.

SOURCE: my raymarine ds600x is losing bottom at 120

The depth loosing bottom would certainly indicate that you may have growth fouling the transducer, however the sea temp 220 degrees indicates possibly a different problem. Start by being sure the transducer is squeaky clean and see what that does for you.

SOURCE: Marine Faria depth finder, with thru the hull transducer.

I'm having the exact same problem. I spoke with the service manager at Faria (Ted) and he was thinking that as long as the gauge is showing a reading, it should default to reading the depth. I'll probably send the guage in to FARIA - they'll repair it for $55. You bring up a good point - maybe the transducer is bad? I put a call in to the Tedmeister to see what he thinks. I'll post if he sheds any light.

i will exchange this for you, free shipping no charge, just ship it to me to inspect and i will send you the transom ducer no charge, if you have a bronze thru hull with speed and temp to trade for a plastic transom mount with speed and temp, let me know

SOURCE: My marine speed transducer needs to be replaced.

Yes. You need to make sure you get the same transducer though. With you system being that old, you may have a transducer that is old where there is not a direct replacement. You need to make sure you get the correct transducer. You may need to get a "flapper" kit to update your housing to the new style.

What can i do to stop the flashing of the depth finder at times it will not show the current depth


Hey Joe,
Wow.. where to start.. there are so many things that will cause the issue you are describing.What type of electronics do you have? Does this happen at all speeds? Where is the transducer mounted? I need more info about when it stops reading.
1.Wrong setting on the unit
2 Bad transducer
3 Bad transducer mounting (either inside the hull or outside the hull.)
4. (In hull) Turbulence going under the boat (mine quits reading at about 55 mph @ half trim...the boat is lifting so much it causes air pockets so the transducer loses contact with the water)
5. (Outside hull) Turbulence around the bottom of the boat where the transducer meets the water.
Good luck,, when you get the info.. reply to me..

I was told that the Uniden QT-206HP depth sounder will not work thru an alunium hull is this true or false


Hi!

The transducer for your depth gauge will not work through an aluminum hull. A drilled through-hull transducer or a transom mount transducer are your options here.

Just in case you require it, your Owners Manual can be viewed/downloaded at:

Hope this helps..

I have a new unit to fit. Can the transducer be mounted inside the hull? It currently gives me strange readings whether inside or out but we are on dry land - if that makes a difference


there are two kinds or transducers out there on the market --- some that can be mounted inside the hull and others that need to be mounted on the outside of the hull, the instruction manual should indicate which transducer you have. AND YES the transducer will only work when you are on the water --- the readings on land are no good and it will not work. install it on the boat and then test the unit on the water. BUT if you do want to test the unit before you install it to the boat you can always take the boat out to a lake ( or wherever ' on the water ' ) and mount the transducer to a long dowel or stick and hang it over the edge of the boat and this will work fine for testing.

Does this transducer mount in the floor of the boat,or on the bottom of the hull?


Hi!

This transducer requires a hole to be drilled in the bottom of the hull and the unit installed from the outside, using a caulk/adhesive such as 3M 4200 or 5200. Nice choice. Furuno is a good manufacturer!

Hope this helps!

My depth finder loses its depth reading at about


You need to set the transducer lower. When at speed, the hull of the ship raises up out of the water and hence your transducer is probably not deep enough at these times to give a proper reading.

A65 Transducer


jmiller,

Sound like your getting turbulence from the hull or your angle is allowing cavitation under the transducer. Look under the hull where the traducer is mounted and look for a part that has no obstruction including saltwater pickups, hull relieves, etc. The other thing to check is to take a strait edge on the bottom of the transducer to ensure the angle is slightly forward than the hull.

Depth finder problem


The problem is not so much the flat bottom, although they are prone to this problem. The way the sonic waves have to travel through the water is affected by turbulence, especially by air bubbles and cavitation, and by the transducer actually leaving the water, which happens frequently on flat bottomed boats. The best solution to this is to have the unit mounted through the hull so it is completely flush with the hull surface - often they are mounted with a surface flange on the outside of the hull which although thin still causes cavitation around the transducer at higher speeds. about 14 knots will usually interfere with the accuracy of the readings on most hull shapes - forward looking sonars perform usually better. Another thing to check is that the transducer is actually seating right in the housing, if it is not flush with the flange then you have problems - even half a millimetre is too much. check no muppet has painted the transducer with antifouling paint - that never helps, also check if there is a build up of marine growth on or near the transducer - a smooth hull will always keep your depth working until a higher boat speed. if the transducer is growing stuff itself then gently scrape it off - be really careful not to scratch the surface. There are now available non-sonic depth sounders, especially ulf radio signal devices, but I have heard no good reports about them, last i saw they were very expensive and maybe they experience other problems at high speed. there also have been towed devices available that may suit your needs better, although probably a lot of trouble in shallow waters. If you can borrow a waterproof video camera, you could mount it behind (not too close) the transducer, this would be a pain to do, but it may give you an insight into what part of the hull if any is causing the problem (tie the camera to the top of the boat securely in case the mount fails) Hope this helps, sorry but your dealer is not totally wrong :)
