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.

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...

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.

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.

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?

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!

Eagle Cuda 128 does not read water depth


Hi Chris, Did you get a fix for this issue? My Dad's Eagle Cuda 128 is also having the same problem - constant reading of 60ft. I'd love to hear if you have a solution. Many thanks,

A test bucket wont work, A 200 khz transducer will generally not work in anything less than 2' of water, due to surface clutter. If the transducer is working, you should hear it make a ticking sound.

When you got the 17000 foot reading was your range set to auto?

How is the transducer situated on the boat? Sometimes turbulence and bubbles from the hull can cause erroneous readings, including unrealistic depths, or no depth at all. Stop the boat and turn off the engin e and anything electrical to see if problem repeats itself. If it only crops up when the boat is moving then it is most likely the transducer location.
