The range of Explorer Primary Light Systems replaces the Helios in Halcyon's line-up. Halcyon's Proteus 3 and 6 Light Systems will still be available to provide the option of an entry-level, lead-acid primary light.

Explorer Light Head Options
Halcyon Explorer primary lights are available with your choice of 21 watt HID, 10 watt focusable or fixed 6 degree HID. Larger coldwater Goodman handle standard; smaller handle is available as optional purchase. The 21 watt head includes an integrated tie-off groove at the base of the cord.

Explorer Delrin Canister
Thanks to the compact dimension of the NiMH battery pack, the Explorer canister is a fraction of the size of a light using a lead-acid power supply. Just like its indestructible Scout back-up light, Halcyon mills the Explorer canister out of a solid rod of Delrin. The one-piece design ensures maximum structural integrity. Delrin shares the same characteristics of industrial metals such as aluminum and stainless steel. Some comparable properties include stiffness, dimensional stability, impact resistance, and structural strength. The one-piece Delrin canister is virtually indestructible under normal usage. Although the canister itself can withstand depths of over 3000 feet, the recommended working depth of the Halcyon Helios line is 300 feet/90 meters.

To complement the Delrin canister, all Explorer lights feature high quality stainless steel fittings and locking latches.

Explorer NiMH Power Supplies

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
