The hybrid mask is great.

Already used and always satisfied. Perfect for snorkeling and short dives from the surface to explore or follow a fish. The automatic switch from the OXAIR mask’s snorkel to the tank’s air is amazing.

Works perfectly

I tested it in our pool, and it works. I filled it with my compressor. You need to get used to the breathing, but it’s a quick learning curve. Runtime is 5 to 8 minutes, depending on the person. Can’t wait to try it in Hawaii next month.

Good experience

My second mini tank. The first one was defective: a permanent leak, and it ended up on a shelf. The OXSEA one is the complete opposite: six uses in a few months, no leaks, no issues. I fill it with my compressor and get about 8 minutes. I couldn’t be more satisfied. I would buy again.

3rd purchase

This is not my first purchase. The whole family has several. Enough said. Perfect for snorkeling and having a backup air supply for quick dives. Easy to use, no issues. My son loves it with the full-face mask. Durable equipment.

No issues.

Easy setup. Fills in about 10 minutes using the compressor. Runtime of 15 to 20 minutes, depending on air flow and your breathing. Easy to use, reliable equipment. Excellent purchase, I recommend it.
