Industry first "sealed" lid design

The Halcyon lid is completely sealed, preventing any water from passing through the lid. This is only possible on designs without open wires penetrating the lid. O-rings must seal any exterior fittings such as with the Halcyon design.

The competition claims to sell a "dry lid which is completely sealed providing protection from water intrusion due to a cut cord or switch boot". Even the casual observer will note that water will migrate along the wires. At best this slows water within the semi-dry lid.

Light signals can be an important means of communication because they work in a variety of situations and are especially effective in gaining a team member's attention. In dark surroundings, individuals can easily communicate with their lights over large distances. Even in close quarters light signals may be preferable, especially if divers are not facing one another. Many open water divers are starting to realize how lights can simplify communication and enrich a dive. Divers frequently use light signals over hand signals because they are:

Easy to see
More efficient to use
Effective at much greater distances
