Diveavenue Expert Review :

The Apollo III 2.0 is the flash we tested for you on moving subjects, and it’s a real game-changer for underwater photography. What we love is the lack of cables thanks to the Lumilink system: your underwater housing becomes more maneuverable, and you avoid snagging on structures or reefs. The green Marelux O-rings are also a real plus for safety, as you can immediately see if the compartment is clean before diving—a detail that provides peace of mind when handling high-end equipment.

Frequently Asked Questions (FAQ):

Is the flash compatible with my housing from another brand ? Absolutely: although optimized for the Marelux ecosystem, it attaches to any 1-inch arm and can be triggered by a standard fiber optic cable from any housing on the market.

Can I safely change the batteries between dives ? Yes, the battery compartment is completely isolated from the flash’s electronics. If a drop of water falls inside when opening it on the boat, it won’t damage the internal components of your underwater camera system.

Why are the seals green ? It’s a very practical Marelux feature: the fluorescent green makes it easy to spot a hair or a grain of sand that could compromise the seal, which is much harder to do with standard black seals.
