Included with M3 Pro

One battery. Two ways to use it.

For your light.

One removable 21700 rechargeable 5,500 mAh battery is included in the M3 Pro kit.

A power bank, too.

Out of the light, the same battery can supply power to other devices through USB-C.

Charge the battery, not the light. Remove the battery and connect a USB-C cable to its port. There is no charging port on the light body.

The modular light system

Handheld. Or 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.

Primary-light configuration

A system configuration, not the standard handheld kit. Confirm the canister, cable and light version together before ordering.

Configuration diagram, not a photograph or a drawing of the actual canister. Canister and cable are not listed in the standard M3 Pro kit.

One interface family

M3 Pro · MURA Pro · SPARK

These models share the connector platform. This does not establish universal canister compatibility: the exact light, cable, electrical specification and sealing version still need to match. M3 and SLB are not included in this connector claim.

Brightness changes runtime.

Read each brightness setting separately. The longest listed runtime is not runtime at maximum output.

High
1 h
Medium
3 h
Low
6 h

High mode includes approximately 20 minutes at maximum output, within its listed 1-hour runtime. M3 Pro has stepless brightness adjustment; these are the manufacturer-listed runtime reference settings.

Manufacturer-listed figures. Runtime varies with mode and conditions. Maximum runtime is not continuous runtime at maximum output.

Technical details

Recreational diving, spearfishing and technical-diving backup. A primary-light setup requires the compatible corded battery-canister configuration.

Why M3 and M3 Pro use a 6° beam

Emergency signalling
SOS + strobe

SOS and strobe modes for emergency visual signalling. Operation varies by model; follow the product manual.

Visual signalling only. Not a substitute for a distress beacon or emergency communications.

Listed beam distance is a technical specification, not usable underwater visibility. A depth rating does not describe visibility.

Understand the light

Reach, brightness and beam width are different choices.

M3, M3 Pro and SLB are all long-throw lights. SPARK also reaches with a narrow beam, while electronic zoom lets you change the beam width.

Long throw
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.
Stepless dimming
M3 Pro adjusts brightness continuously. Brightness adjustment does not, by itself, change the beam angle.
Electronic zoom
SPARK changes between narrow and wide illumination electronically. Choose a tighter beam for reach or a wider beam for nearby coverage.

Questions, answered.

Help with choosing, delivery and support.

Can M3 Pro become a corded primary light?

Yes, with the compatible corded battery-canister configuration. Confirm the exact light, canister, cable and electrical version together. A shared connector does not mean every battery canister is compatible.

Is six hours at maximum output?

No. Six hours is the manufacturer-listed reference for low brightness. Medium is listed at three hours. High is listed at one hour, including an approximately 20-minute maximum-output phase. M3 Pro has stepless brightness adjustment.

Which light should I choose?

M3 Pro is a long-throw handheld light for recreational diving, spearfishing and technical-diving backup. For a primary-light configuration, ask us to match the compatible battery canister and cable; they are not listed in the standard kit.
