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.

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.

Used this buoy on a trip with friends. Really easy to use and boats saw us quickly. Rolled it up and shoved it in my pocket when done.

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

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.

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.

Bright color makes me feel super safe in the ocean. I even spotted my buddy’s float from really far. Packs away small so it’s never in the way.

Helps my dive group stay together. I could see everyone’s marker even when waves got choppy. So helpful when currents started picking up.

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.
