You might try adjusting the Grayline setting. It's purpose it to distinguish between hard & soft bottoms. Press MENU, select GRAYLINE, the scale appears like when adjusting sensitivity you can adjust up or down with arrow keys. Get over a non reading soft bottom then adjust. The change is reflected on the screen as you adjust it.

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.

Hello! Do you have the PDF users guide for your unit? I'm looking at a copy in the troubleshooting section...I don't want to cover information you have already looked at or tried...Since I do not know if you have that manual I'll give you a few items to check...

Measure the battery at the units power connector...Must be at least 11 volts DC...In portable mode it uses 8 D cell batteries= 12 volts
Make certain the Transducer is securely connected...
Did you use the in-line fuse supplied with the unit?...
Try the Manual Depth Range...First turn off Auto Depth Range...From the sonar Page Hit MENU...Down-arrow to Auto Depth Range...Hit ENT...Hit Up-Arrow to Depth Range...Hit ENT..
And the Depth Scale Range appears...Up-Arrow or Down-Arrow to select a different depth range...Hit Exit...The minimum depth the unit can read is 5 feet...

If you do not have the PDF guide, here is the link...

It sounds like your transducer has gone bad. You may be able to find a replacement on Craigslist or eBay, since this is an older model. Transducers are pretty sensitive to bumps and drops because of the crystal inside.

When at speed i tend to lose sight of the bottom it becomes very broken. Also the depth reading takes a while to record depth.


What you are experiencing sounds like air bubbles crossing the face of the transducer. If you have a transom mount transducer check the face of the transducer. Make sure that it is clean. Also make sure the front of the transducer is a tiny bit lower than the back. The digital readout on the screen will only happen when you have a strong signal of the bottom.

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.

In lakes that are not clear I have trouble adjusting my x96.


This depends on how muddy or clear the water is. If muddy or there is a LOT of floating sediment in the water, most fishfinders will have trouble getting a good image through the dirty/brackish water. You might not be doing anything wrong in this case.

Sensitivity and grayline are your main adjustment settings, assuming you have your transducer located correctly at the right depth in relation to your hull and the waterline as well.

Does the clutter extend all the way from the surface to the bottom? If so, try reducing sensitivty... if clutter is moreso near the surface or top of the screen, then this is probably because the transducer is getting aerated water or distrubed water over it and causing the clutter and readings.

As a good rule, match the sensitivity setting tot he grayline setting. I.e. if you have sensitivity at 90%, put grayline at 90% also.

Hope that helps!

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.
