After seeing this post
Trip Report - Key Largo with Rainbow Reef, I decided to re-read my review and realized I missed replying to
@Capt Jim Wyatt
We were asked if we wanted to follow a guide. We had never dove these sites before and said yes. This doesn't excuse pairing us up with air divers on AL80's and the short dive times. We were not originally aware until the last minute that we were with air divers. We questioned it and were told that's our group. After the dive, I questioned it again and was met with excuses. They didn't adjust the groups, that's on them.
Pickle Barrel dive, avg depth 18ft, was only 42 min long, including our safety stop. Knowing we weren't going to get full use out of a 120, we opted to use their al80's on this dive. Surfaced with 1800 pounds of air.
Conch Wall, average depth of 58 ft, including the safety stop, 34 minutes. Ended with 1500 pounds of air using my 120 (only started with 3k for some reason).
Spiegel Grove, we had a slow descent, took about 5 minutes to get everyone down. 15 min diving around, and 9 minutes to get the group to the surface up the rope. Total dive time, 29 minutes, avg depth 61ft, max depth 91. Since I was on a rental reg, I don't have my air pressure recorded in my dive log, but we had plenty.
If we were paired with the nitrox group, who dropped in first and were still on the wreck upon our group starting our ascent, we would have had more time to enjoy the dive. Or when we signaled to the dive guide that we'd like to join the other group (I pointed at myself and then pointed at them), he adamantly signaled for us to follow.
