Compact. Bright. Built for Professionals.
Delivering 190Ws of flash power, the Retra Flash Pro Max II achieves a 65% increase in actual light output over the previous generation—all without adding size or weight.
This performance boost comes from a fully redesigned reflector, enhanced electronics, and an improved triggering system that channels more energy into light and less into heat.
The pilot light has been upgraded to deliver 120% more brightness, providing enhanced visibility and pinpoint precision when using the LSD snoot.
Fast. Reliable. Efficient.
25% faster recycle times bring Li-ion performance while using widely available and travel-safe NiMh batteries. No compromises. Just faster shooting and consistent power delivery in even the most demanding situations.
Enjoy up to 2000 shots at 25% power with the 8xAA configuration, giving you unmatched autonomy during extended sessions.
Built for Harsh Environments
Durable gold-plated contacts provide enhanced corrosion resistance and reliable electrical performance, even in the most demanding underwater conditions. Designed for longevity, they ensure consistent connectivity in both the strobe and battery caps, giving you confidence dive after dive.
Instant Readiness and Precision Control
The Retra Flash Pro Max II powers up instantly with no wait time in BATT/TEST mode, so you're always ready to shoot. With 17 selectable power levels, you have precise control at your fingertips, allowing you to fine-tune output for any lighting scenario.

Description of modes
The BATT/TEST mode allows you to check the battery status of your strobe. Test your strobe’s flash output or use it for creative lighting techniques with long exposure.
Retra Flash Pro Max II emits a single pulse of soft light at the selected power level. You can fine-tune the strength of illumination with 13 power levels of ~0.5 F-Stop increments, giving you a total of ~7 F-Stops, without accessories.
Retra Flash Pro Max II uses your camera’s calculations to determine the ideal exposure for the scene by using a pre-flash. You can adjust the relative power of the automatic exposure if you feel it was too high or low.
Retra Flash Pro Max II is capable of emitting a long flash pulse, required for HSS photography. You can fine-tune the strength of exposure to suit your specific needs.
The U1 and U2 modes allow you to tailor your Retra Flash experience. Select your custom user mode by connecting your strobe with the Retra UWT App. You can choose between Smart SL, Manual Low Power, or LED Adjust modes.
You can rotate the display 180°, making it easy to read and control the Retra Flash Pro Max II no matter how it's mounted or positioned underwater.
And if you ever find yourself in an emergency, the strobe can emit an SOS signal in Morse code, overriding any active errors to ensure your distress signal is seen.
Retra Flash Pro Max II features a 1.000 lumen pilot or guide light with two intensity levels, allowing you to find the ideal position for your strobes quickly and easily. You can also customize the intensity of each level with the LED Adjust mode in the Retra UWT App.
Pilot light feature is available in M, TTL, HSS, and U modes.
