with the utmost caution to enjoy !!!

se a very valent and shapely snorkel, but that it is a model with self-closing valve, I have only found when I unpacked it. under the splash protection hides a mechanics with swimmers snorkel closes as soon as one plunges into the produktbeschriebung was nothing to.

I have a part used in a classic last vacation, descend to snorkel with. unfortunately makes the valve from time to time when deep breath after surfacing unexpectedly close, so if and when you need it most air. I found living dangerously, so I removed the entire valve mechanism. from there it was a very useful snorkel.

no idea if this is due to my way of snorkeling or if I have a Monday model caught, but I can only recommend the snorkelling and to test its functioning relaxing in shallow water, not to panic, should the valve at the wrong moment close make and immediately remove the valve in the case, or to exchange it for a different model, if you do not feel the tinkering. Upon delivery, I found it highly questionable in my case!
