Product Information

The SeaLife Sea Dragon Duo Flash Set (model SL988) is a dual-strobe underwater lighting kit offering nearly two times the light coverage of a single Sea Dragon strobe. It pairs two Sea Dragon flash heads with diffusers, a Flex-Connect Dual Tray, and two Flex-Connect Grips, and the whole system is depth rated to 200 feet/60 meters.

Who it is for

This set suits underwater photographers who already shoot with a camera that has a built-in flash and a standard tripod mount and want to cut backscatter, eliminate shadows, and get nearly double the light coverage of a single Sea Dragon strobe. It works with SeaLife DC cameras as well as Olympus, Canon, Sony, Nikon, and other brands that meet those two requirements, making it a flexible upgrade path for divers moving from a built-in flash to a true two-strobe lighting setup.

Compatibility and sizing

The set is universally compatible with cameras that have a built-in flash and a standard tripod mount, including SeaLife DC cameras, Olympus, Canon, Sony, and Nikon models. It does not work with SeaLife SportDiver smartphone housings, the ReefMaster RM-4K, or Micro Series cameras.

Frequently Asked Questions

Does the Sea Dragon Duo Flash Set work with SeaLife Micro cameras?

No. The Sea Dragon Duo Flash Set does not work with SeaLife SportDiver smartphone housings, the ReefMaster RM-4K, or Micro Series cameras. It is designed for cameras with a built-in flash and a standard tripod mount, such as SeaLife DC cameras, Olympus, Canon, Sony, and Nikon models.

What batteries does the Sea Dragon Duo Flash Set use?

Each flash head takes 4 AA batteries (not included): about 150 flashes with alkaline, 250 with lithium, 500 with rechargeable Eneloop Ni-MH.

Do I need Flex-Connect Flex Arms with this flash set?

Flex Arms are optional but recommended. Because the Duo Flash Set adds a second strobe, spreading the two heads apart with Flex-Connect Flex Arms helps create even, thorough illumination of your subject instead of two lights pointed from the same narrow position.

What is included in the Sea Dragon Duo Flash Set box?

The set includes two Sea Dragon flash heads with diffusers, a Flex-Connect Dual Tray, two Flex-Connect Grips, an optical cable with adapters, two cable plugs compatible with Olympus and Sea & Sea housings, spare o-rings with a tool, an instruction manual, and a deluxe travel case.

Great purchase and "Like New" as advertized.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.
