Loss of depth reading over 15kph, is usually caused by either turbulence from under the chines of the boat, or that the transducer is toe up, or back end up. If the transducer throws up spray, it is back end up. Toe up is harder to see. Get someone to drive the boat and look overboard. The transducer needs to be flat at the speed you want to see the information, and of course that changes depending it you are trolling or on plane and your trim.

Not marking fish could be a faulty transducer or that the sensitivity setting is not set high enough. Read the manual. I am a Humminbird person :>)

SOURCE: When turning on the Lowrance

here is the link to your the lowrance web site. the trouble shooting guide says that if you tried to it on another boat than you might need to take it in for service. but there is a section that explains how to do a soft reset on the unit. you might try that.

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 Lowrance X-51 is not reading the depth sitting

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 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.

SOURCE: My depth finder loses its depth reading at about

You need to set the transducer lower. When at speed, the hull of the ship raises up out of the water and hence your transducer is probably not deep enough at these times to give a proper reading.

My new Lowrance Hook-5 GPS isn't working, I'm a noob, how do I get this function working?


'isn't working' is such a broad problem. If it is only the GPS, it is covered from Page 49 of the manual and shows you can access Satellite information. Note, it almost certainly won't work in your garage or storage. It need to see the sky as the antennae is internal.

The unit has an installation guide. In my personal opinion, it is better to let a professional boat engineer install it, mainly for the correct fitting of the transducer on the stern. Correct placing makes all the difference to a good set up, unless you intend to fish without the engine running.

All they need is mounting, power through a fuse direct to the battery, and the transducer fitting. Then you put the boat in the water and switch it on.

Why don't I see fish on my lowrance elite5 hdi fish locator


Sounds like you do not have your transducer connected.
You will know it is working if you have a bottom sounding. If you have a bottom sounding (depth reading) and it is correct then you may have to fine tune the finder to see the fish.
I have the same finder on my boat. http://njsaltfish.com/index.php/captainsfocus?sid=61

Doesn't work on fast flowing river


Many depth finders don't work when the transducer sees a little turbulence. My only suggestion is to try different locations for the transducer, trying to guess where there will be the least turbulence beneath it. This is easy if your transducer is mounted inside the hull and reads through the hull. Not so easy if it is a through-hull mount. Be sure it is mounted correctly to the hull if it is mounted inside the hull.

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!!

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.
