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

Loved how easy it was to inflate during my last dive! The colors really stand out against the water. Fits right in my gear pouch.

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.

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.
