Yes quite possibly... But a few things to try/check first before you go out and get a new transducer...

1. Ensure the transducer is fully submersed below the waterline when floating and when on the plane... try lowering it more if you can.
2. Check the surface of the transducer itself (the underside) pointing down... If there are any minor scratches or scuffs, this can effect its function or performance. Minor scratches or marks can be sanded out with fine wet/dry sandpaper (at least 400 or 800 grit).
3. Isolate any electrical wires running near or next to the transducer cable. Also check connection of cable at head unit, and that the pins etc are clean, free of corrosion and making good contact.
4. Take your head unit to your Lowrance dealer and they may have a transducer there to use to diagnose whether it is indeed the trasnducer or a problem with the head unit.

Good luck!

SOURCE: Lowrance x96 does not function after 20 feet depth

Your transducer needs to be adjusted so the return signal can be picked up. Some of these have to be super tuned to receive the signal. Also the transducer may be moving ever so slightly when the boat is traveling at speed. You may have some water turbulence interference all contibute to signal return.

SOURCE: 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??

Lowrance troubleshooting

Pay attention if depth readings shift during times when moving from spot to spot at higher speeds. If this is the case then you have air bubbles disrupting your sonar signal causing inaccurate readings or a loss of bottom lock for the unit. If over this weeds in shallow water, this at times creates havoc with sonar readings because of the wide variance of signal returns.
check the voltage at the head unit.You should have a minimum of 11.7 volts. 12.5 to 13.5 is optimal
lower power input can affect the overall performance of your unit.

How do i find water depth

Water depth should show automatically on your sonar page.
if it does not then either you have selected "stop sonar" under your sonar options or you have opted to turn off the depth displayou so the numbers don't show up.
if you areally viewing your GPS or split screen sonar/GPS page, sometimes the depth display is not visible on these pages unless you specifically instruct the unit to display it.

The GPS component of my Lowrance Elite-5 Gold is malfunctioning about 50% of the time.

Hey Les, Since you have replace both the unit and transducer, you have eliminated/diagnosed most of your problem.. Its in the wiring... sometime when I am in full GPS mode I get erroneous depth readings..?? Have you tried a different GPS module (the "puck")?

My fishfinder will not continue to read shallow depths as well as in shallow depths when drifting and occasionally running across the water. My unit is a lowrance 522c color gps/fishfinder.

Hello. Your observation is spot on and it is actually a characteristic that is always true when using sonar. Yes, your Lowrance uses the same sonar as a nuclear powered submarine does. The two factors you focus on, water depth and boat speed are perhaps, the two biggest factors when it comes to the quality of the fishfinder. The boat's engine should be in gear at an idle or just above. Experiment with your boat to find the best throttle location for good arches. Usually, a slow trolling speed works best. The depth of the fish can determine if the fish will arch on the screen. If the fish is in shallow water, the fish is not in the cone angle very long, making it difficult to show an arch. Typically, the deeper the fish, the easier it is to show an arch.

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?

Proper set up for lowrance sonar

Where do you use your boat?

There are so many variables it's hard to fit it all here, but there are some excellent tutorials on the Lowrance website. The most important thing is to pick the right frequency, for the depth of the water. (200khz for less than 70', and 50 khz for greater depths). Depending on how serious you are about fishing, there are a lot of extras that you may never use. The key is to figure out which features will help you the most and forget about the rest.

You may also get some help at this link: FixYa Service Directory

It's common for SONAR to lose contact with the bottom at high speeds. The better the transducer installation, the faster you can go. Turbulence and bubbles will cause the SONAR to drop out. Lowrance's transducer installation guide explains it very clearly.
