Water Temps: We all had a computer with us that read out the water temps. Everyone was around 51-53. It was 51 in the bottom of the deep end. That's how I figured out how cold the water was, not by some random guess or assumption.
Rental Gear: We thought, Boss thought, that we had all the gear we needed here and wouldn't have to rent anything. Although we have about 4-5 wet suits and 1 dry suit, none fit myself of the other guy who was using our stuff. We have a few tanks, and fins, and various other small stuff, but not nearly enough to piece together a full equipment set. Needless to say, we had to rent the gear: $175 between the two of us. However, the rental originally was from yesterday until the end of Jan. Now we get to keep everything until we are "done" with our tests.
