How about a dive watch? Strap it to something heavy enough to stay
put on the bottom of the pool (a rock, a chunk of brass) and then you

How about just a plain old waterproof watch?

Also an ordinart $3.50 wall clock from Walmart encased in a clear
plastic bag would work.
But not the kind that need to be plugged into an outlet....

No problem there ...

Any way to add a timer to the pump? When the water current stops, time
to get out.

An underwater light that goes off or comes on at the end of a timer
cycle would probably work as well. Or unless pool is in full sunlight
all the time, perhaps a waterproof strobe light above the splash zone,
which could be completely separate from the existing pool setup. Looking
at a dive watch would break the swimming rhythm, and a clock on the
bottom would have to be awful big to be easily readable.

If all he is trying to do is telling himself when to get out (not
interested in lap times, etc), then all he really would need to do is
set an alarm clock for however long he wanted to swim and then get out
when it went off. Battery operated or even a cell phone.

Not so sure that will work due to noise of the water, both the pumping
and his splashing as he swims.

Not to mention, how do you do timed laps in a wave pool? You are not
actually moving relative to the edges of the pool, as I understand it.
Duration of the session is about the only thing you can time.

Good point. I sometimes miss the subtleties a three or four
responses in (grin)

I have an effective timer I use on our exercise machine (the one that is set
up, as opposed to the one that is up in the garage attic)--when it feels
like I'm going to throw up my heart, I stop. Oddly enough even though it
feels like a half hour, the built-in timer on the machine usually lies and
says it was just a few minutes.
