Default Lowrance LCX-26c HD shallow water performance

Have any of you guys who have the LCX graphs had issues with them working in shallow water? I have two LCX-26's and neither of them will read in water less than 5' deep. In water shallower than 5', they both just flash as if they can not find the bottom. Certainly this is not normal. Any feedback would be appreciated.

I have LCX 111 and have no problem tracking bottom down to 1.5 ft, but if the transducer is not parallel to the bottom of the hull then you could experience this issue. I found this out when I knocked my transducer slightly out of position.
Also make sure you have the latest software loaded. The current revision is 1.7.
One of the parameters listed on lowrance's web site is improved bottom tracking in shallow water (<9 ft). I'm not sure in what software revison this was implemented, but if you have never updated the software this could be your issue.

I have the 1.7 code in my LCX-26's and the 1.9 code in my LCG 2000. I am getting the same result from both of my units. I have one transducer on the trolling motor and the other one is mounted in the sump. I don't think that the transducers being out of position is the issue especially with the transducer in the hull. I will recheck the one on the TM. Any other thoughts?

I usually have to dial back the sensitivity setting for my 27c to work properly in less that 5ft.

Turn off the auto sensitivity and adjust it down to between 85 and 90. This should help.

I have my transducers networked together and Lowrance thinks that I have one bad transducer that is causing problems with both units. When the units are networked together, they send digital depth information back and forth. Next time out, I will troubleshoot this by using both units without having them hooked up to the network. I am hoping that I find a bad transducer. That will be easy to correct.

My bayou is generally 4 to 6 feet with a 2 foot sand bar (winter time depths) and my XCL 26 reads down to about 1.5 feet--then it looses the bottom--I have other brand sounders which behave the same.
