Its basically a 1.5 litre water bottle cut in half with two slits cut down the side to fit over my YS120 strobe, the opening of the bottle is where the light comes out. I then duct tape it in place and all over the bottle to ensure no light comes out. The opening that you see on the end of the it is actually a smaller bottle that i have cut and slid onto the end of the water bottle and then duct taped in on there as well. The opening is approx 1cm across, quite small. Good for snooting a pygmy actually as the water bottle opening itself is too wide. I can take the smaller bottle off underwater if i want a larger beam. It may look ugly.. but it works and the duct tape holds forever as long as it doesn't get banged. There is no snoot on the second strobe so i can use that if i need a full powered shot.
Total cost.. $3 maybe?!
However, don't try to use it with a 105mm and 2x teleconverter on a pygmy when there is a lot of surge in the water.... hahaha.. that was 45 mins of endless frustration this morning
