Kit For Shallow Sumps Etc ?

Probably the most dangerous creation I’ve seen yet.

Thoes masks have an issue with work and breathing and Co2 retention in snorkelers let alone a diver working hard pulling themselves along. Plus several snorkeler have died due to IPO and other issues in them. They are also much harder to clear and seal than a normal mask.

The bottles are tiny and very low pressure plus there is no gauge so no way to know which breath will be the last.

It’s mounted in a way that it’s a complete snag hazard so when you do catch it and rip it off your face not only do you lose you mask but your air supply as well.

If people want to try short ducks with a bottle go find your local friendly cave diver most of us are more than happy to help people out. Though be warned favours are often called back in for carry’s.
