Cheap And Nasty Snorkel extension
That is a very dangerous idea but the reason why isn't immediately obvious.
When you exhale you will fill the long tube with your expelled air and then breathe it all back in. I believe this would result in hypoxia (oxygen deficiency) in which case you could drown without realizing what's happening. Snorkel tubes are short so most of the exhausted air is expelled and there is enough of an influx of fresh air to avoid this problem. "Lloyd Sumpter" wrote in message news Hi, Whenever I need to work on my prop, etc. underwater, I've just slapped on the mask and fins and held my breath. But I've always wondered: why not rig up a hose arrangement to be able to breathe? We're not talking 50-ft depths here, so I'd think it would be pretty safe. Perhaps some kind of non-collapsable hose on the end of a snorkel? Does anyone do this? Why or why not? Lloyd Sumpter "Far Cove" Catalina 36 |
