Basicly whatever is deemed safe at the time.

If you were doing an Open Water course and you had been
at 6m for 45min, then 10mins changing cylinders and off you go again.

If however you were on a course that had a proper dive, say 20m
at least, then there would have to be a decent surface interval prior to
you doing another 20m dive.

What is frowned upon is not getting out. In other words surfacing
and then going back again even if it is only 6 mts. Part of any
basic course is the repetition of kitting up, doing buddy checks etc.
Basic familiarisation with kit is very important.

I've had to re-teach many a diver who skipped or more lilkey
was told to skip, this bit on there basic course.

The answer is, "it depends".

It is a procedural, not scientific, determination.

If you are using tables, the length of time to drop a letter group is
the answer.

Most computers will start a new dive sequence after an arbitrary surface
interval, usually in excess of five minutes.

If yer a sat diver, ya eat dinner and catch some sleep and yer still on
the same dive.

For me, it's the length of time to change tanks plus eat a banana,
except in winter when I add five minutes of hot shower.

I'll fill your tanks, no cert card needed.

And many that you do not know about.

It's not an easy question to answer. If you're on most tables, your dive
time stops when your direct ascent begins. Once you've reached the surface,
you really can't count anything as the same dive, even though you may be in
the same repetitive dive group. For dive computers, it depends on the
computer. I think mine considers a dive done after 10 minutes. The time
probably varies from one manufacturer to another.

The best answer I can come up with is "it doesn't matter." You plan the
dive or dives according to the tools of your choice, be that tables,
computer or custom tables developed by a computer program run on the surface
and do them according to your plan . . . or according to what you're
computer thinks is OK.
