Question about Lowrance Boating

1 Answer

I HAVE A 332C. IT IS MOUNTED BY MY STEERING WHEEL. I AM NOT SURE WHERE THE TRANSDUCER IS MOUNTED. MY UNIT IS ON A RANGER COMANCHEE 520. THE PROBLEM I AM HAVING IS THAT MY UNIT IS SHOWING THE IMPROPER DEPTH AND AT TIMES JUST SHOOTS UP A CRAZY NUMBER LIKE 234'! i AM NOT SURE IT IS THE UNIT ITSELF? I AM NOT IF IT THE TRANSDUCER? i BOUGHT THE UNIT NEW AND TAKE IT OFF WITH EACH TIME I TRAILOR MY BOAT TO A PLACE TO FISH. DIXIE MARINE OUT OF FAIRFIELD OHIO DID THE INSTALL BUT THE TRANSDUCER WAS ALREADY IN FROM THE PREVIOUS OWNER. KEEP IN MIND, LABOR IS $95 AN HOUR! i HAVE NO IDEA WHERE TO START. I DO KNOW THAT THIS UNIT WAS PRICEY AT AROUND $750 SO I AM EXPECTING IT TO PERFORM. I LOOK FORWARD TO ANY HELP AND DIRECTION YOU MAY BE ABLE TO GIVE. SINCERELY, ANDY OLDS

    THANKS FOR THE INFO. I THINK I WILL CALL THE INSTALLER AND SEE WHAT THEY SUGGEST. I AM QUITE SURE THE UNIT IS FINE. I HAVE A NEW 135X UP ON THR TROLLING MOTOR AND WORKS GREAT. IF I FIND OUT IT IS IN THE HULL, SHOULD I RECOMMEND REPLACING IT WITH A SKIMMER JUST OFF THE BACK OF THE BOAT? HAVE ANY IDEA WHAT THE COST OF A NEW TRANSDUCER WILL COST? i HAVE LOOKED TONS BUT BUT FOUND NO LISTING FOR A 332C SPECIFICALLY.



    THANKS,

CLICK HERE for the 332C manual if you do not have it.

It has been my experience that if not married properly - the transducer and cable can become breached - and water enters the connection and starts the corrosion process.

Have a good search for the transducer.

If you have a trolling motor installed - look down near the prop -

I HAVE A 332C. IT - 8ceccf7.gif

some even have them built -in! You'll have to trace down the wire when its on the trailer out of the water.

Sometimes a sensitivity adjustment can be made and it will solve the problem.

Many times there will be an object - like glass or metal that will deflect the sonar and make it act up.

If you are getting it only occasionally - i would suspect debris on the bottom - if the range is out consistently - the transducer is at fault. There are many places to mount it - so tracking it down will fall on your shoulders :D

Your 332C can only translate the info it gets from the transducer - so you're on the right track. Locating it, and testing the connection and wires is the next step. If you cannot locate it - you may just opt to purchasing another - and mounting it yourself to save the labor cost of someone else doing it - and you'll be problem-free for quite a while.

    From page 84 of your manual:



    Automatic Sensitivity

    The default sensitivity mode is automatic. The unit bases the sensitivity

    level on water depth and conditions. When the unit is in the automatic

    mode, sensitivity is automatically adjusted to keep a solid bottom

    signal displayed, plus a little more power. This gives it the capability to

    show fish and other detail.

    However, situations occur when it becomes necessary to increase or decrease

    the sensitivity. This typically happens when you wish to see

    more detail, so an increase in sensitivity is indicated. Or, wave action

    and boat wakes can create enough tiny air bubbles to clutter much of

    the water column. In that case, a decrease in sensitivity is indicated to

    reduce some of the clutter.

    The control bar used to adjust sensitivity up or down is the same

    whether the unit is in the automatic or manual mode. In automatic you

    can adjust sensitivity up to 100 percent but the unit will limit your

    minimum setting. In auto, the unit will continue to make small adjustments,

    allowing for the setting you selected.

    In manual mode, you have complete control over sensitivity, with the

    ability to set it anywhere from zero to 100 percent. Once you select a

    level in manual, the unit will continue to use that exact sensitivity setting

    until you change it or revert to auto mode.









    ADJUSTING THE SENSITIVITY starts on page 85.

    I'd go for the easily accessible rear skimmer installation called a Transom Mount.


    CLICK HERE for the types that are available.

    CLICK HERE for a page with a few good Garmin Transducers with different mount styles and applications - the most expensive of which is $119.

    Most are interchangeable (industry standard) - just make sure the plug matches your 332C - or find an adapter.

    eBay may be a good place for you to start looking. Often good used ones can be found there pretty cheap.


    Good luck!!

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!

All Lowrance systems have an in-line 3 Amp fuze. My guess is that when it broke and fell off the fuze shorted out. Look back the power sypply to the unit and you will find the in-line fuze. Replsacit with a new 3 Amp fuze and you should be up and running.

Sonar does not appear to work - not picking up depths or bottom structure. All other functions look good.


This problem is most likely linked with your transducer.

1. Check your transducer cable and make sure the plug terminals are clean, as well as the plug on the back of the unit.
2. Make sure the transducer cable is plugged in correctly and securely.
3. Make sure the transducer is in the water and mounted according to the directions, parallel to the bottom of the boat
4. Turn the unit on while the boat is in the water, but with the engine OFF.

IF it works when the engine is off, but vanishes when the engine is on, you may be having electrical interference.

IF it works when the engine is running, but vanishes when the boat is moving, it is a turbulence problem. Move the transducer.

IF it does not work at all, try borrowing a new or a "known good" transducer and seeing if it works then. If so, replace the transducer.

Let us know if these work or now.

Built in transducer is not picking up/transferring depth to graph


I havew a Minn Kota trolling motor on a Z21 Ranger. Minn Kota has a built in (puck type) transducer on the motor. I have a lowrance 135x on the front. The lowrance will read the temp but will blink the depth. I switched out the depth finder with another 135x with the same results. I have a 522c gps unit networked together and mounted on the console that works fine. Any suggestions on the problem with the 135x?

Embedded

I was looking to see if I could find a replacement for the display and was able to confirm that the transducer is a single beam 120khz unit so I doubt that you've find a replacement for it ..as is .

The Airmar C-49 is the proper number for the connection line but like me I think your going to have to think about a whole new unit and or system . Been there already.

Best of luck.

Lowrance x135 not functioning properly


Had the same issue with another brand. Turned out the transducer cable was picking up noise from other cables (power, trolling mtr. etc). Try moving the transducer cable away from any other cables. I put the cable in a 1/4 " plastic housing up to the point where it was above deck and it stopped all the strange stuff. Not sure about the temp issue??

Transducer is mounted on a plastic bracket to trolling motor. when trolling motor is turned on, black vertical lines appear on my screen. lowrance x107 cdf


Are you utilizing another unit in your dash? If so, sometimes when both units are on and in sonar mode, their frequencies will intefere with each other causing the vertical lines. I would suggest turning your dash unit off or lowering it's Hertz rate from 200Hz down to 50Hz.

Funny story...I saw this same issue on my boat years ago. I had an X102C up fron and an LCX-19c in the dash. I acutally thought it was some sort of man-made structure and spent time fishing it...DOH!

Installing an old used lowrance fish finder


I don't think your old fish finder is the LMS-332C GPS Receiver listed above in the description. You don't need the speed wheel for the fish finder to function just the transducer and transducer mount. You should mount that on the back of the boat towards the center but not too close to the motor and not too close to the side of the board. Don't let it hand below the level of the boat. That should keep it from getting hit by the trailer or dragging on the bottom. Try to make it as level as possible. The green and white wires may be for the speed wheel but i'd need a model number for clarification. Hope this helps.
