I make my own snuffer bottles now, none were overly good for underwater sniping.
I did like the Garrett the best though, but it still wasnt close to my design.
The Snuffer bottle that I make costs about $10 dollars but is the best snuffer bottle for underwater Sniping that I have ever used.
It is an 8oz bottle with a 3x longer tip that curves to help get into hard to reach spots, being curved makes it easier on your wrists as well.
The tube also gradually increases its inner diameter so that clogs are not an issue.
It is a hard plastic too so if can be used to lightly push stuck gold from cracks or clay without breaking the tip.
Its an overall awesome sniper bottle, I might end up selling them.
