Retra Flash Pro Max II underwater strobe

The Retra Flash Pro Max II delivers 65% more light output, 25% faster recycle times, and a 120% brighter pilot LED. It sets a new standard for power and reliability—all within the same compact form factor as the previous Pro Max generation. The Retra Flash Pro Max II is retra's most advanced professional strobe yet, engineered for photographers who demand the highest performance, reliability, and flexibility on every dive. 

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.

Classic Bayonet Mount 
The bayonet mount is an easy to use twist lock mechanism at the front of the strobe. The bayonet mount allows you to attach a selection of accessories that shape your light or change its color temperature. The bayonet mount remains the same on all Retra Flash models and allows you to change photography styles on the go.
