Question about Raymarine A65 Combo GPS Chartplotter/Fishfinder

1 Answer

A65 Transducer I have flat bottom boat, Bay Rider to be specific. I get no depth reading from my transducer at any speed other than low idle. The speed and water temp work so I know the transducer is communicating. There is probably interference occuring, but I have moved it several times with no affect. Is there a preferred location/position to mount the 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.

My Garmin depth finder/gps combo is giving me a false depth reading,like way way outta sack,not a foot or two. It came as an extra on a boat I purchased and elsewise seems ok,just inaccurate depth. Is it...


YOUR TRANSDUCER MAY BE SET FOR HORIZONTAL MODE...MEANING FROM BANK TO BOAT, NOT DEPTH...CHECK THE TRANSDUCER TO MAKE SURE, IT IS AIMING DOWN, NOT OUT...OTHERWISE YOU'LL NEED TO CHECK YOUR MODE SETTINGS IN YOUR MENU.

YOU CAN ALSO DO A TEST ON YOUR TRANSDUCER, BY SCREWING IT ONTO A BROOM STICK ...ADJUST THE TRANSDUCER DOWN, CHECK YOUR SETTINGS ON THE SCREEN, THEN DO A SIDE TEST WITH THE TRANSDUCER TILTED SIDEWAYS TOWARDS THE BANK AND CHECK YOUR SCREEN!

THEY CAN BE TRICKY...AND ARE VERY SENSITIVE, BUT ONCE YOU FIGURE OUT, HOW YOU WANT TO USE IT, YOU'LL LOVE IT!

HOPE THIS HELPS!

Hi, Check for debree on depth sensor under boat. As you said check for fuse(s) Good luck.

Raymarine a65 transducer 200kh fine 50kh not reading bottom


First do a factory reset and determine that all the setting are correct. You can get this info from the manual. Remember you will loose any saved way points when you do the reset. If that does not sort you out;Remove transducer from transom mount and duck tape it to a broom stick so that the transducer face is facing down. With the boat standing still in calm water and the ducer hooked to the DSM25 push it below the water and see if it see bottom on 50khz.The idea here is to get the ducer in another location to see that it is not getting reflections of the boat. 50Khz is very prone to reflecting of stuff around it. If you still have a problem I would send the ducer and DSM25 unit back under warrant .No need to send A65 back it should not have a problem.

Sonar not working properly, intermittent


Generally, that indicates air bubbles in the water under the transducer. If you have a transom-mount transducer, make sure the bottom surface is level or angled slightly down. If you have a thru-hull, make sure your bottom is fairly clean in that area.

A test bucket wont work, A 200 khz transducer will generally not work in anything less than 2' of water, due to surface clutter. If the transducer is working, you should hear it make a ticking sound.

When you got the 17000 foot reading was your range set to auto?

How is the transducer situated on the boat? Sometimes turbulence and bubbles from the hull can cause erroneous readings, including unrealistic depths, or no depth at all. Stop the boat and turn off the engin e and anything electrical to see if problem repeats itself. If it only crops up when the boat is moving then it is most likely the transducer location.

Depth sounder problem


If the transducer is mounted off of level, an error is introduced due to angle. It is a fixed percent offset, say 10%. so 10 feet reads 11 and 100 reads 110. There is an offset function to read depth below ducer, depth below keel, and depth below waterline, but these are fixed amounts in feet, not a percentage. Look at the transducer when it is operating, boat angle considered.

No depth reading while on plane.


Depending on your transducer type, you may have a liquid filled type that simply needs refilling. If this is the case check for leaks and get it redone. If not it could be transducer placement or cavitation under the hull.

False fish readings


False fish readings are commonly caused by electrical interference such as alternator noise, and by air bubbles flowing across transducer.

For starters make sure your fishfinder is on an independent circuit and not on one powered by your ignition switch. In other words, you should be able to turn your fishfinder on, even though the engine is turned off. Ideally the fishfinder should be wired directly to the battery with an in line fuse.

Try running the boat at a speed slightly higher than trolling speed, then kill the engine, as the boat slows down to trolling speed do you still see false echos? If yes then the problem probably lies with how the transducer is mounted, or where it is located on the hull.

If you don't see the false echos when the engine is off, it may be necessary to reroute the transducer cable to keep it away from the boat's ignition wires. You can get transducer extension cables if necessary. Also there are filters that you can buy that suppress alternator noise buy attaching between the battery and the engine.

Another common cause of false echos from electrical interference is a transducer cable that has been cut and spliced.

I hope this information helps. Please reply if you have any questions about my response.

Depth: Could be for a number of reasons, too deep for the sounder - check the manual for it's max depth. Dirty water, sounder unable to penetrate through to the bottom. Weed or other debris covering the transducer. Transducer on a swing mount & being pushed out of alignment then dropping back in once stopped.

Speed: Is the speed readout controlled by a GPS or paddlewheel? If it's GPS, check the power connection of the sounder, may be loose which would also cause the depth to 'drop out'. If it's paddlewheel, you're down to bad connections or faulty unit.

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 :)
