A few things worth knowing.
Quick answers, drawn from our product guides.
Which light should I choose?
A concentrated beam designed for reach. M3 and M3 Pro suit recreational diving, spearfishing and technical-diving backup; SLB focuses on compact long-range search.
How do I charge it—and can the battery power other devices?
M3 · M3 Pro · SLB
Remove the battery and connect a USB-C cable to its port. There is no charging port on the light body.
Out of the light, the same battery can supply power to other devices through USB-C.
Does maximum runtime mean maximum brightness?
Manufacturer-listed figures. Runtime varies with mode and conditions. Maximum runtime is not continuous runtime at maximum output.
Listed beam distance is a technical specification, not usable underwater visibility. A depth rating does not describe visibility.
Can I use my light outdoors on land?
All 3QRS lights include temperature protection and support outdoor use on land. Choose the light and brightness setting for the task.
Can M3 Pro become a corded primary light?
M3 Pro works as a handheld light. Connect the matched corded battery-canister setup to configure it as a primary light.
A system configuration, not the standard handheld kit. Confirm the canister, cable and light version together before ordering.
Where can I check delivery and find the right manual?
For shipping and battery-delivery questions, email service@3qrs.com with your model and destination country. For an existing order, include the order number. Use Product resources to request the correct manual for your model.
