Help Me Understand Guide Number: DS51 vs. D2000 vs. YS110

Oh.... you are using the EV controller for its slave function.. sorry did not know you were talking about that aspect of it.

Humm...also knowing you are using a point and shoot helps.

Not really tried to look for that feature. I know the UFL-1 oly strobe has a built in slave sensor, but the ev controller allows for the sensor to be in a different location than the strobe.

I believe the YS110a can be wired to a an EV controller, and used the same way. (with the understanding that I have never tried this).. it does have a hard wired connection, so it would just be getting the correct cable.

Yea, the only USA maker of this sort of stuff is Ikelite, so they are the only ones still showing feet.

My confusion was due to Ikelite using feet and metres, and assuming Sea and Sea's GN was listed in feet, when it was in fact, metres.

The EV manual controller with an ikelite strobe is the perfect solution for off camera strobe use, where the diver is 10 feet away from the camera. Fiber optic cable would not only be in the photo, but would be an inconvenient way to do this.

I've only been on a few dives as a model with this setup, but it works pretty reliably and well. I wanted to start with strobes that will allow me to move up to that system in the future once I have more strobes.

I'm not a camera idiot, but all of my experience is with land based SLR's mostly with ambient lighting, and carrying a point and shoot on a lot of dives in caves, using ambient light. I've enjoyed the photography I've already done, but super slow shutter speeds and ambient light only go so far, adding a strobe is a definite priority.
