Diving Breathing System with Snorkel Mask (L/XL), Portable Motorless/Tankless Snorkel Breathing Equipment, 6.5FT Underwater Depth for Snorkeling, Scuba Diving, Pool Swimming, Fishing

I know how to snorkel and I have my own full face mask that I love. But I bought this so that I could go under my boat and look at the zincs and check for barnacles. The mask is very uncomfortable. But I could have lived with that for the short time that I would be under water. The major problem is the breathing tube. it bends at the top of the mask so easily and cuts off the air supply. The tube is too flimsy. I tried so many workarounds but could not get it to allow me to breath under water. If the tube had some sort of corrugated reinforcement, I think it could work. Thank you Amazon for allowing me to return it.

I purchased this thinking it might help when cleaning the bottom of my pool. Unfortunately if your head get more than 1.5’ below the surface the tubing starts to collapse and eventually at 3’ you cannot breathe at all.

The media could not be loaded. I had hoped to use this for simple pool cleaning. There is simply not enough airflow for an adult, and it occasionally "plugged" with nearly zero airflow at all at depth greater than 3 feet. Not good if you're underwater! I assumed it was defective and Amazon replaced it. The replacement was a bit better, but it appears the plastic air hose collapses under pressure. Unusable. The design and materials are not satisfactory. It needs a larger diameter hose, and it should be more rigid. Maybe it's just me, but I prefer breathing freely. Breathing is good. Not breathing is bad.

As soon as I go 2 ft or more under water, the mask starts pouring in water through all the air check valve. Even trying to use the snorkel alone (connecting tube to a standard snorkel) won’t work because the line the goes up topside, collapses anytime I try to inhale. This might work if the tube was sturdier. Works at a max depth of ~1ft before pressure collapses tube and you suffocate.

My mask starts to leak as soon as it is fully covered with water. With less than a few inches of water column pressure the mask seal leaks and the mask get fully filled of water in seconds.
