Is 700ft high enough to be concerned about the dive/fly rule?

You should be fine. We went parasailing to 800ft in Hawaii on the same day I did a three tank dive, and I was fine. I think the significance is any height over 1000', but you may want to wait a day if possible just to be safe.

LOL, I actually never would have thought about this as being a problem. I don't have an answer for you, but welcome one as well.

Just to be safe I guess I could Parasail first

I've heard 1000ft as well, but best not trust the internet for an answer on such a thing. Call your instructor, or consult your training manual.

You might even try a call to DAN.
Your not going 700' in the air. They let out 700' of line. You probably are not over 200' up.

DAN would be a good resource. One thing to consider is HOW altitude (WATER/AIR) has an effect on our bodies in relation to the BENDS. At 66' we are at 2 Atmospheres. When surfacing from that depth the pressure reduction on your body is enough to "pull out" the N2 in your body.... IF that reduction in pressure is FAST enough and the concentration of N2 is large enough.
The Density of Air is MUCH less than that of water and thus it takes MUCH more altitude to have an EQUAL effect on your body and pulling out that N2. You'd have to know how much or how high one atmosphere in Altitude would be in order to get some sort of idea about how high you can climb in an airplane.
Most General Aviation airplanes don't go high enough to pressurize and if flown LOW might be safe enough to fly in after diving...... BUT that would all depend on surface interval (amount of N2 released from your body) this reducing the amount of N2 and increasing you safety.
A little long but I'd be curious to hear your comments and thoughts on this.
