[CA] [CA11] eS127 system stationary depth issue

[SMS]

I have a boat with a factory installed system / 3 each eS127 and 1 eS128 also an I70 , wired Quantum Radar and a ECI100 connected to the Cummins engines. All software is at the 19.03 date .The transducer was replaced and is a B744 with a fairing block. The original transducer was the same model but did not have a fairing block
The customer issue is the same as before the replacement/ seeing depth readings while stationary of 45' while in 6' of water, moving while offshore it reads 25' in 300'.
The readings are not consistent , at the dock when I am on board it was reading the correct depth.
In the settings the transducer is set as a B744 and all other settings are factory after a factory reset was done.
The transducer was switched to the eS127 next to the Master / changed that to Master and there was no change in the issue.

On an other issue- 1 of the eS127 units doesn't display the Shallow Depth Warning, it does see the other units on the Network

One of the eS127 units was replaced due to a bad touchscreen and was replaced with the eS128. I have another eS127 with the same issue now also.

On writing this I will go back and run a test cable over the deck from the ducer to the helm to eliminate that .

My thought was, there is some interference in the system created by the multiple 127 / 128 sonar units or the i70.

Thank you Chuck
