Gave me reassurance each time I surfaced away from my boat. So light that I forget it’s even in my pack until I need it.

This buoy is now in my regular dive kit. Inflates fast and rolls up small. Had a blast showing my friends how well it works underwater.

Just the thing for extra safety. I trust the bright color to signal boats. Doesn’t take up much space in my gear. Glad I got it.

Nice bright markings, quick to spot! I felt comfortable surfacing far from the boat. Packs down really small. Buying another for my brother.

I really like how quickly you can pack it away. The colors make all the difference if you drift a little too far. Solid build.

Easy to spot in choppy water, even from far away. Super easy to inflate on the go. Takes no time to fold up afterwards.

A friend recommended this to me. It’s simple to set up and really handy if you get separated. It survived my trip to the rocky coast just fine.
