| Primary light head:
Divers should carry the light head of the primary light in their left hand with the light cord coming directly from the canister. While diving, neither the cord nor the light head should be passed under the long hose. When the light is no longer in use and/or is failed the light head should be clipped to the diver's right chest d-ring and the cord tucked under the waist belt and long hose so as to allow the long hose to be deployed without interference of the light cord.
This routing prevents several problems. For example, divers running their cord under the hose and then clipping off to the D-ring (during a failure, gas switch, or events requiring two hands) will be faced with a troublesome entanglement should they need to share gas. Divers are also forced to make a minimum of two passes under the light cord on every dive of their lives (starting the dive and ending the dive) assuming minimal additional equipment. Divers utilizing additional equipment (such as stages) would be required to make this pass under the hose each time they make a bottle switch (ie the light is often clipped to the D-ring). This elevated number of unnecessary activities accumulate on ever dive merely to simplify an already very simple issue. |
