Product Information

The Sea & Sea YS-01 Solis is a compact underwater strobe with DS-TTL II circuitry, a guide number of 20, and a 75m/250ft depth rating. This listing does not include the fiber-optic sync cable, which must be purchased separately.

Who it is for

The YS-01 Solis is built for divers shooting with a camera and built-in flash who want the strobe to read and match that flash output automatically. The DS-TTL II circuitry sets exposure based on the camera's onboard flash intensity, and a light level control dial lets a diver dial intensity stronger or weaker from the programmed standard exposure. For example, if you run two YS-01 Solis strobes, one on each side of a subject, you can turn down the dial on just one strobe to lessen light on a brighter element in the scene, such as white soft coral, without touching the other strobe.

Compatibility and sizing

The DS-TTL II circuitry works by reading light intensity from a camera's onboard flash, so the strobe is intended for use with a camera that has a built-in flash. A fiber-optic sync cable is required to connect the strobe to that camera and is sold separately from this listing.

Frequently Asked Questions

Does the YS-01 Solis include a fiber-optic sync cable?

No, the fiber-optic sync cable is not included. It is required to carry the camera's onboard flash signal to the strobe and must be purchased separately.

What batteries does the YS-01 Solis use and how many flashes do they provide?

The YS-01 Solis runs on 4 x AA batteries. Alkaline batteries deliver about 230 flashes with a 2.5 second recycle time, while Ni-MH batteries deliver about 300 flashes with a 1.9 second recycle time.

Can I adjust the YS-01 Solis light output per strobe?

Yes. The light level control dial offers 10 steps from GN 1 to GN 20, and the DS-TTL II exposure control allows adjustment from +4 steps to -5 steps off the programmed standard exposure, so each strobe in a multi-strobe setup can be tuned independently.

What is the depth rating of the YS-01 Solis?

The YS-01 Solis is depth rated to 75m / 250ft.

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.
