Dive Essentials

The little things make a difference between a good dive and a great dive. Details such as a proper-fitting mask, the perfect-sized utility pocket, or a well-organized diver notebook can make all the difference. Whether you are a beginning recreational diver or a seasoned explorer, Halcyon has the right collection of dive essentials to get you where you want to go.
Halcyon offers two styles of mask. The single lens mask fits a wide variety of divers; our low-profile, dual lens mask is very popular for those seeking low-volume masks. Both masks are made from the highest quality silicone components and tempered glass.

Halcyon pressure gauges are as reliable as they are accurate.
