“While traveling I have numerous times wished I had my gear with me. But the effort to bring heavy dive equipment is often too hard and is left behind. Then cost to rent is sometimes too much for just a short session. “

This makes it possible to jump in the water and spend a few extra minute down below. Its compact light weight and lets me pack it in my luggage or put it my gear bag for road trips to the lake, river, or ocean. I love snorkeling and this is perfect for a short shallow water dive. This thing looks pretty tough and the built very well for its compact size. It’s has plenty of uses outside of just snorkeling such as dropping something in the river or lake and having to go down and look for it. You can inspect for damage under your craft. What important to know is that this is a short experience.

Its a ton of fun and great for travel.


Underwater heat escape, shallow water diving challenges, etc.


Spearfishing or capturing underwater landscapes with a camera.


It can be used as backup air for 30 meters underwater, escorting you at critical moments.
