Diving is a great leisure activity, whether you’re partial to night diving, a dip during broad daylight, or you prefer to explore underwater caves. Dive snap light sticks are essential tools in diving, especially for night dives and cave diving. To navigate underwater and return to the starting point, divers require dive lights like snap sticks to serve as a trail, path or a lifeline. Snap light sticks help illuminate the diver’s path and are used as a tracking device and as a tool to help divers identify each other under water. These sticks use a chemiluminescent substance in plastic tubes that provide illumination to track, mark and signal for hours, and they’re easily turned on and activated by bending the stick.

In industrial diving, these little lights come in handy for underwater repairs because of their buoyancy and because they can easily be transported and attached to any device, as they have a hook and a gate top for hanging. The dive snap light sticks function best in temperatures between 40 to 80 degrees Fahrenheit or 4 to 27 degrees Celsius. The illumination, brightness and duration of the light’s usability is determined by the water temperature. The snap lights work at higher and lower temperatures, but are less effective, especially in temperatures colder than 40-degrees Fahrenheit/4-degrees Celsius. They are, however, not affected by humidity and atmospheric conditions.

Snap light diving sticks are used for marking before embarking on a repair operation. They help identify the working areas that are fully submerged, as well as potentially dangerous areas divers should be cautious of. They aid in diving under ship hulls, and are also used in maintenance work like welding cracks or removing blockages. The dive snap lights are waterproof, non-sparking and non-flammable, which makes them useful tools in situations where sparks could cause an explosion. The light sticks are also non-toxic and recyclable. Activating the light stick is simple: you just bend, snap and shake the tube.
