I was diving Spiegel Grove a week ago and lost one of my two Ikelite Pro-V7 LED video lights.
It seems that rough surface and rough seas loosened the nut enough so when I was surface swimming from one mooring ball to another and one of the two lights sunk and now resides in about 120ft of water around Spiegel Grove
Just wondering a few things:
1. Is there a better way to attach the light and tighten so it will not happen with 3rd light (I guess I need to buy me 3rd light but it will be a while as they are not cheap
2. Any suggestion for a backup so in case nut loosens again there is a backup preventing separation?
