That link sent me somewhere crazy! I tried to insert the amazon link and it simply 'disappeared' - that hasn't happened in the past. I think it's a cool whistle, btw.
Storm whistle or tank air supplied Dive Alert? I have to duck my head in the water when I use my Dive Alert.Hyper Whistle says it produces up to 142 dB, I wonder how that compares to Dive Alert, I could not find specs
The Storm whistle inventor made a video about those...
This is from a Cozumel Divers FB group:When I first joined DAN they were giving out these nifty name tags that are also signal mirrors. I've worn it ever since. I carry an SMB, and I learned how to whistle about as loud as most of the regular whistles - but that one that @Johnoly posted looks good.
I hope things turn out well for this diver. I'd really like more details to help me determine what I can do better to avoid this happening. That said, sometimes things happen you simply can't prepare for - and 'you don't know what you don't know'.
Thanks for the information Bilboinsa. Friends and relatives of victims are discouraged from reading these discussions as we try to learn from them. It was great of you to stick with the wife and help as possible.Please be respectful of the lost diver and his grieving wife. We spent hours consoling her last night and this morning.”
I've long thought that Cozumel currents are too little discussed. Vacation divers should know how to escape one.A sudden down current pulled him down before anyone could help.
