Question Spiegle Grove double dip typical dive time and surface interval?

[chrisjur]

I was initially thinking about diving a deeper mix for the first dive, then clipping the tank (should have around ~20-30 cf left) as a stage bottle for the second dive for redundancy.

Also, just a note that if you are not diving with a guide and do want redundant air, they will rent you a pony bottle. Not a bad idea.

We did the Spiegel Grove twice with Horizon. We dove single AL80s with 30%. I think the total dive time (including ascent and safety stops) was maybe 35-40 minutes per dive. Surface interval was maybe 45-60 minutes. Max depth on dives ranged from about 95-105 feet. First day we hired a guide just for the two of us, which I think was a good idea for the first time on the wreck. We liked it so much, we dove it again a few days later -- this time on our own. Definitely a very cool dive site.
