[CA] [CA11] Axiom 9 RV Sounder issues

[Chuck - Raymarine - Moderator]

ktcarter,

Our engineering team was unsuccessful in duplicating the problem shown within your videos. Their feedback follows ... see the requested additional information:

From the information available, I have not been able to recreate this issue onboard Raymariner.
My Setup:
Axiom 9 RV with TH split 12 degree bronze 'ducers. Bench 5 ... note that this differs from ktcarter in that his system utilized an RV-100 transducer.
NO STNG connection
S/W at 3.8.97
Internal GPS on, but no GPS Fix
Factory Reset unit after downgrade to 3.8.97
English (US)
Fishing (fresh water)
Boat details left to default
Navionics card in uSD card slot at the back
Split Chart/Sonar app
Surface filter set to 0 manual
Interference Rejection to high
2nd Echo interference Rejection set to high
Range set to auto
Depth source auto
Bottom fill on
In this configuration there was no bottom loss. Even when aeration was significant.
To further diagnose this issue we would need to find out things like what his source of depth was, what his surface filter settings were, whether there were any other MFD's in the system etc.
