So far AVS has had positive feedback from those who have tested it. Many surprised that they noticed the difference.
The Spitfire is already forgiving of vents but still most feedback we have had is that yes it works and is noticed.
I’m not sure that the solid particules that makes water murky, have a bearing.
Besides my local waters are deemed by the international diving community as some of the clearest in the world.
If I tweet the above and say it’s a great deal. Maybe it’ll carry more weight.
