Question about Lowrance M56 Sonar/GPS and M68c Sonar/GPS GPS Receiver

Wiring new gps/sonar unit to existing speed sensor on boat

I recently purchased a Lowrance M68C speed sensor for my boat. Can an older speed sensor on the transom be spliced into the new unit? The cables do not have the same number or colors of wires.

Hi, its unfortunate that the new speed sensor has a higher and different wiring set up with the old one,hence the old one cannot be spliced into the new unit.


Thanks and take care

My lowrance elite 4 HDI goes black when i get on plane so my backtrack feature doesnt work


The speed of your boats travel only directly affects your sonars ability to read the water depth.
your backtrack feature is GPS based. These is not affected by your boat being on plane.

Your screen being black sounds like your sonar is losing bottom contact due to air bubbles passing under the transducer. This is a common occurrence with most boats.

Add some details regarding what your seeing and we can help you get a better handle on your difficulty.

Does the x510c have a speed and temp transducer or just the paddle seperately


Hi Rick

There is only one transducer. for speed/temperature. From page 2 of the owner's manual (see link below)
"A single-frequency with built-in temperature
sensor is packed with the X-510c"

Hope this helps and happy boating!
-Steve

I have a lcx 110 lowrance graph that wont power up at all. i replaced all the wiring to the unit and tested the plug at the unit all of that is good i also cleaned the connections still nothing. any ideas?


I have found several units that have the same problem. All turned out to be a defective keypad. And almost all are specifically the power button. Not something Lowrance will repair. I've been purchasing some of these units for parts. If you still have it I might be interested. jadamec@yahoo.com

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.

Cannot get a GPS signal to my 525c DF


This may or may not offer help but on the lowrance site it has very simple step by step instruction to solving this problem. The first step is to make sure your getting power to the new 4000 series. With a 12v tester you can do this. On the gps unit there is 3 different power sources. One is main power, two is sonar and three is power to data. One you have power going to the 4000 then proceed to other options. I hope you didnt pay full price for your 4000. Lowrance has a replacement process and replaced my 2000 for a 4000 for $120 (2 day shipping). Back to your situation... Out the back of the data will the a cord that connects into the bottom of the T, and the a resistor on one side and the 4000 on the other side.

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!
