In answer:

1. You don't need to touch the screws. Once you hear the click as you push the catches over they are pretty much locked. Not had any problem with mine. As the port is pressurized at depth it is held in place. The only time I think it becomes vulnerable is getting in and out. (Maybe Ken will be along to give his opinion on that!).

2. I use an extendable lanyard. I had to get a big split ring and this is around the tray, between the handle and main casing. I have a pretty heavy duty one, so when I set off my DSMB, I collapse the strobe arms, clip the lanyard up and the camera hangs down nicely. I wouldn't want it on a wrist, as in an quick emergency it could be in the way.

3. I can see about 90% of the viewfinder with my mask right up next to it. I'm afraid you'll just have to get used to it. Other manufacturers do magnification eye pieces, not aware of one for an Ikelite. Even though it's not perfect, I would still keep with the eye-piece than use live-view (if I had the option), as you can see it's in focus properly.

HTH,
