Frequently Asked Questions

What cameras and strobes work with the SeaLife Flash Link Optical Cable?

This cable is compatible with all SeaLife or optically synced flashes and strobes, and it connects to SeaLife underwater cameras. It is designed as the sync connection between those two components, so any optically triggered flash in that compatibility range will fire through this cable.

How long is the SeaLife Flash Link Optical Cable?

The cable measures 16 inches, or 41cm, in a coiled, flexible design. Its durable casing is built to prevent kinks in the optical channel while still allowing it to flex as you reposition a strobe on a flash arm.

Does the Flash Link Optical Cable include a way to mount it to my flash arm?

Yes. The package includes two hook-and-loop ties specifically for securing the cable to a flash arm, in addition to the one Flash Link Optical Cable itself, so no separate mounting hardware is needed.

What is the Flash Link cable made of?

The optical fiber core is Polymethyl-Methacrylate Resin with a Fluorinated Polymer cladding in a step-index profile, rated at a numerical aperture of .50. The outer buffer/jacket is pink polyethylene marked Eska™ Premier, and the fiber has a tensile strength of 70 N.

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.
