[TG] [TG11] Axiom sounder image clutter with RV transducers

[Tom - Raymarine - Moderator]

Hello Strbass28,

Yes, please do send us images, I'll be able to give you more concrete information once I can see what you're seeing. A couple of comments in the meantime though:

• If you haven't done so already, I'd suggest having a read through this FAQ on sounder performance troubleshooting. I wrote that some time ago to help answer this sort of question.
• If you have lots of near-surface clutter then you can reduce that with the Surface Filter control in Menu > Adjust Sensitivity. Surface Filter is effectively the old TVG which is used to selectively suppress near-surface clutter. You should use the lowest level of SF that you can - too high and you can suppress wanted returns - but it will help clean up the top part of the water column if you have a lot of clutter from particles in the water, wave action etc.
  

Once you can post some clear images back - both as you normally use the sounder and also ideally in the diagnostic gain setup described in the FAQ - then I can go further.

Regards,
Tom
