Product Information


This innovative, super buoyant dive buoy can be easily inflated to 0.15 BAR with the included pump.

Its 50 litre capacity makes this buoy super buoyant.

It has a very large valve with a two-way system for easy inflation and rapid deflation.

Mares has equipped the Hydro Propel buoy with multiple functional features, including eight large nylon D-rings on the sides and two large lower D-rings. The lower D-rings have optimised tow points to minimise drag on the surface of the water.

The buoy comes with a distinctive 20cm x 20cm dive flag. A large mesh pocket can be found on the top. The buoy is also equipped with two adjustable elastic straps for attaching a speargun or other equipment.

Freedivers and spearfishers can easily carry this ultra-light buoy thanks to the shoulder strap and, once in the water, can attach their equipment directly to it.

The Hydro Propel Buoy is the perfect companion for divers, freedivers and spearfishers.
