This submersible laser pointer is designed to provide diving signal guidance. It is mainly used for underwater teaching by professional scuba diving instructors, and to facilitate underwater communication between divers. It has an electronic anti-reverse design, temperature control, PCB protection, and low-power protection. The power of the green laser is up to 150mW, and the output is stable even at 100 meters underwater. This model has passed FDA and CE certifications, without customs issues. All accessories are available without any additional cost.
Multiple Internal Protections
This laser pointer adopts professional PCB protection, temperature control, and low-power protection functions. A unique electronic anti-reverse installation design is available, which will not cause damage to the laser even if the battery is installed incorrectly.
High Power
The green laser pointer is high-power, long distance, and stable. It is not only suitable for diving, but also for astronomy use.
100-Meter Waterproof Depth
This submersible laser pointer uses a special double-layer waterproof seal, which can 100% pass the 100m waterproof test for scuba diving.
Aluminum Alloy with High-Thickness Oxidation
The product housing is made of high-quality aluminum alloy as raw material, and is professionally treated with high-thickness hard oxidation. It is sturdy and resistant to seawater corrosion.

Instructions for use
1) Battery installation:
① Hold the laser pointer with the head facing up, and turn it clockwise to remove the laser body. ② Insert the battery in the correct direction. ③ Turn counterclockwise to install the laser body.
2) Switch function:
You need to keep pressing the power button to keep the laser working. If you release the power button, the laser will turn off.
3) Charging Instructions:
① Plug the charger into the charging socket. When it is not connected to a battery, its indicator light is green. ② Put the battery in the charging slot. The charger indicator light is red to indicate charging, and green to indicate the battery is fully charged. ③ The battery must be kept away from flammable and explosive materials when charging; the charging plug must be unplugged after charging is completed.
4) Low power prompt and protection:
When the power drops to 10%, the green laser will flash 3 times, and then enter the energy-saving state. When the power drops to 5%, it will automatically shut down for protection (to prevent excessive discharge of the lithium battery).
Notes:
1) Disassembly by yourself may damage the green laser pointer.
2) Before each dive, please carefully check the laser body to ensure both waterproof rings are intact. If there is any crack or dryness, it needs to be replaced or coated with silicone oil.
3) The battery must be removed from the laser pointer when not in use. Please charge it in time after each use. If it is not used for a long time, it must be charged at least once every three months. Do not knock the battery, and protect it from heat, moisture, and corrosion.
4) Do not let children use this laser.
5) Do not make the green laser beam directly into the eyes of people or animals.
6) Please do not let the laser work continuously for more than 5 minutes on land, otherwise the diode may be damaged.
