I have had the 998 for about a month and have had it on the water 4 times. In every case the recorded data indicates duplicate data and "shears" where the time shifts abruptly to up to 30 minutes across one pixel row/column.
I have tried viewing this in the following viewers;
SonarTRX
Humviewer
Deepviewer
All display the same information incorrectly. In addition to the views being screwed up the length of the recording is incorrect. It is as thought it goes through periods where it does not record anything. (hence the shears) What I view on the screen does not "feel" like enough bottom to justify the time on the water.

Has anyone experienced this? PLEASE
