Unmatched Beam Versatility: Spot to Flood

The standout feature of the OrcaTorch ZD710 MK2 is its wide-to-narrow zoomable beam.

  • The 4° Spotlight: Perfect for low-visibility or murky water, cutting through the dark to highlight specific marine life and serve as a crisp underwater signalling tool.

  • The 72° Floodlight: Ideal for clear conditions, night dives, and illuminating wide reef walls, photography and videography.

Reliable Power

The torch itself boasts intelligent overheat and over-discharge protection, as well as reverse-polarity protection to prevent improper battery installation.

The package includes a high-quality 5000 mAh 21700 rechargeable USB-C battery with a charging indicator, which does not require a charge dock or cradle. A spare battery can be purchased separately to facilitate multiple dives or days of diving by changing the battery. 

The battery level indicator on the torch gives a clear view of power levels during your dives. A flashing red light indicates that power is below 10%; a steady red light means power is between 10-30%; and a green light shows power is at 30% or higher. 

Renowned OrcaTorch Reliability

When you are deep underwater, your primary light cannot fail. The ZD710 Mark 2 carries OrcaTorch’s tested and trusted durability, featuring a rugged, corrosion-resistant build and a 150m depth rating that technical and recreational divers alike can rely on.

If you need a versatile, powerful, and reliable, adjustable beam scuba diving light that excels in any environment, the OrcaTorch ZD710 MK2 is a clear winner.

Product FAQs

How does the Orcatorch intelligent thermal protection work on land?
Water is an exceptionally efficient heat conductor, and the ZD710, designed for underwater use, is engineered to dissipate heat directly into the surrounding water. If you turn the torch on while on land, it lacks this passive cooling environment. And long-term use on land is not recommended for these types of dive lights.

However, to prevent the high-powered LED and the internal driver circuit from overheating, melting or degrading, Orcatorch integrates an internal thermal sensor that continuously monitors the temperature.

If the core temperature reaches 65°C (149°F) on land, the flashlight's active temperature control engages, automatically reducing the output to a lower-brightness mode. This safety measure drastically reduces heat generation and prevents permanent damage to the LED and battery, though the light should still be used on land only for brief periods and at lower levels.
Why does the beam intensity (candela) change so drastically while lumens stay the same?
Lumens measure the total amount of light emitted by the torch, while candela measure the intensity of light in a specific direction. In the ZD710 MK2, the light output remains steady at 1,500 lumens on Turbo, but the beam angle can adjust from a wide 72° flood to a narrow 4° spotlight.

When you adjust the torch to a 4° spot, the optical lens converges the 1,500 lumens into a highly concentrated area. This skyrockets the beam intensity up to 212,500 candela, allowing it to cut through murky water, illuminate deep crevices, or serve as a long-range signalling device.

Conversely, shifting to a 72° flood disperses those same 1,500 lumens over a broad area, reducing the candela but providing soft, even illumination perfect for underwater photography without harsh hot spots.
How does the safety lock function prevent battery drain?
In a dive bag packed with heavy gear, shifting can easily compress the side button switch of a flashlight, accidentally turning it on. If this happens on dry land, the torch will generate extreme heat and completely drain the battery before you even reach the water, cause significant damage to its surroundings.

To prevent this, the ZD710 features an electronic lock. Press and hold the side switch for 5 seconds when the light is off to engage the lock; the main light will blink twice to confirm. In this state, pressing the button does nothing except light up a small green indicator to show it is locked.

To unlock it for your dive, you simply double-click the button. For absolute safety during air travel, it is still highly recommended to unscrew the tailcap slightly to break the circuit.
Why does the Turbo mode only stay active for a brief period, can I override it?
On the ZD710, Turbo mode is accessed by holding down the side button for 0.5 seconds. However, this peak output mode runs continuously for only about 1 minute before the light's active thermal management steps down the brightness.

Divers often wonder if they can override this to keep it running at maximum power. The short answer is no, and you shouldn't try. Because high-output LEDs generate intense heat, stepping down the output protects the battery and internal circuitry from degradation.

While you can manually force the light back into Turbo mode by pressing the button again, repeatedly doing so on a dive will rapidly drain the battery, drastically shorten the LED bulb's overall lifespan, and potentially trigger a complete thermal shutdown.
Is the wide 72° to beam angle sufficient to use as a "primary" video light?
A common question from underwater photographers and videographers is whether the ZD710's flood setting can double as a high-quality primary video light. While it is incredibly useful for general area lighting or for lighting the foreground in casual Go-Pro-type shots, it has limitations for professional or high-end video use.

When zoomed out completely, the ZD710 produces a wide, evenly distributed beam covering about 72°. However, dedicated underwater video lights typically offer an even wider beam (up to 120° or more) to fully illuminate a wide-angle lens's field of view without leaving dark edges.

Additionally, standard dive lights like the ZD710 prioritise cutting through water over high Colour Rendering Index (CRI), meaning its beam may not bring out the rich, true reds and oranges that a specialised video light with high-CRI emitters would.
