The Sea & Sea YS-01 Solis Underwater Strobe is a compact slave flash that can be used for wide-angle or macro photography. With its circular beam angle of 100 x 100° and a guide number up to 20, it is suited to point-and-shoot, DSLR, and mirrorless cameras. The DS-TTL II technology gives you automatic exposure control when shooting in slave mode, along with a manual control with 10 stops. The strobe connects with your camera via fiber optic cable.
The YS-01 Solis is powered by four AA batteries which will deliver up to 300 flashes at full power with NiMH batteries and 250 with alkaline cells. With NiMH batteries, recycle time is a fast 1.9 seconds (2.5 seconds with alkaline batteries), so you can capture all the action on the reef. The LED target light is 40% brighter than the previous YS-01 model.

I currently have a YS-03 strobe and am looking to add a second strobe, possibly the YS-01. Do you know if I can link the two strobes so that the strength of the YS-03 flash is controlled by the YS-01 strobe in manual mode?
The YS-03 is an auto only strobe, and uses a pre-flash. So the YS-03 exposure is set by the camera's built-in flash. Since the YS-01 does not use the pre-flash in manual mode it will not fire. To use the YS-03 and the YS-01 together you have to set the YS-01 on TTL, not manual.
It is best to use two YS-03, or even better to use two YS-01.
