Hey there,
I’m going this weekend (March 14), and don’t have a buddy. I’ve dived the gardens once before, and my dive times were:
28min to 120ft (avg 68)
41min to 92ft (avg61)
47min to 95ft (avg 53)
54min to 76ft (avg 54)
34min to 74ft (avg 54)
41min to 86ft (avg 60)
34min to 85ft (avg 34)
I watch my air, and might swim a few feet above my buddy if I’m consuming too much air. I swim down if there is anything interesting to observe, and ask that my buddy makes regular checks up to see if I need to surface.
