Question about Sport & Outdoor - Others

Open Question

Over half the time I use my lowrance X50 depth finder that I just bought 4 months ago I get vertical lines that repeat every 1/4 inch on the screen. I get these whether sitting still on the lake, travelling fast, in shallow (2 feet) water or deeper 40 feet of water. This has been happening since the first time I used it. The transducer is installed on the transom per operating manual directions and the cable from the transducer to the unit does not run a long any other electrical lines in the boat that I know of. The unit is mounted in the front about 12 to 18 inches from my bow mount trolling motor and about 24 inches from the battery I hooked to power line directly to. What could be causing this?

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!

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??

SOURCE: my fishfinder will not continue

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.

SOURCE: Can a HDS 5 Lowrance

Hi, well I am sorry to be the bearer of bad news but those two are NOT interchangeable sorry. The "Drive Current & Voltage" for the Transducer are not the same at all, in fact i don't even think that the "pin outs" are the same? but cannot remember off hand? Unless specifically indicated by the manufacturer, one cannot usually swap transducers among instruments, if one does/did do so, well indeed the transducer maybe damaged and or the output of the sounder maybe damaged as well?
These manufacturers actually make it so that none of their equipment is interchangeable, as they wish to maximize the profits you see, and if one could just swap things among models etc, then "They" would, in their mind anyway "loose out"
So you will simply have to cut a new hole and mount for you new transducer. make sure you mount it in the manufacturers recommended place, the Bow is fine, although I often recommend that it be central to the craft, but, sometimes this isn't possible for varying reasons.
Sometimes if one must retro-fit a new transducer to an existing but different size etc site, then, it is best to "Fill" the old mounting hole(s) with a suitable material, and then re-drill and re-mount it all again.

The depth finder on my elite 5 Lowrance blinks if I go over 14 mph. And the screen gets very hot after a few minutes of run time?


Hey Robert,
the blinking is usually the result of the transducer losing contact with the water..
As far as the screen getting hot.. that is not good.. do you have this unit mounted in dash? It needs some ~cooling.. just some airflow..

My Mark 4 sometimes shows incorrect depths. The transducer has not moved and no problem with electrical. One point it is working fine, the screen then runs multiple vertical lines and the depth chan


Take note if when the vertical lines appear on the screen if the depth numbers begin to flash. If this is the case then the transducer has lost bottom contact and the unit is trying to reacquire bottom contact. If the transducer is parallel to the bottom of the lake while your boat is not moving then, the next time you have it on the trailer, turn your unit on and go listen and or feel the transducer to see if you can hear and or feel the tick or sonar ping. If you can't your transducer may be faulty. If the loss of bottom contact occurs when you are moving it will happen at a certain speed. This is the result of air bubbles passing under the transducer and disrupting the sonar signal causing loss of bottom contact.

Lowrance Elite 4X fish finder that reads between 1.5' and 2.5'


Hey Anon
The transducer installation is more important than anything.. next to correct wiring! You must make sure the mounting is good,,, if its outside the hull, make sure its sitting 1/16th below the hull with no obstructions.. if its inside the hull, the medium you used to fix the puck to the hull must be porosity free and the puck sitting as level with the WATER as possible..
Now, take the manual to the lake with you and DO NOTHING but read the manual and apply what you read to the unit,,, read -repeat - read-repeat.. forget about fishing... now read-repeat and learn... IF nothing seems to be reading correctly.. its probably the transducer installation.. YOU DID use a/the transducer specifically for this unit!!

Lowrance depth finder missing adapter cable


I own a 1995 Four Winns and what you need is a Lowrance LSM-1 depth finder unit. It accepts the two pin lead from the transducer and send the depth reading to the dashboard display via the 6-pin connector. There is also a three wire harness (red/blk/wht) that connects to a power supply.

The reason I know all this is my depth finder fried a couple years ago so I removed the Lowrance LSM-1 from the boat in order to find a replacement. Unfortunately, this was an OEM part that is not available from Four Winns or any aftermarket source. Probably your best bet is to look in a boat salvage yard or purchase an aftermarket depth finder.

Bought a 1995 Four Winns boat inthe dash it has a lowrance dept finder. under dash i see a 6pin male round connector & 2 pin round male hareness is there a harness i need to connect the 2 or what would...


Hi- I have a 1996 Four winns boat with the same problem. I believe we are missing an adapter cable which goes from the depth cable to the instrument panel. I have not been able to locate this cable yet. If I find it I will let you know and can you do the same for me if you locate one?

This problem is usually the ribbon cable connection at the top of the stripe. Reseat the cable first. The other possibility is the panel itself, but that is rare.
Keep us posted.
