It is very easy to spend a whole day at this quarry. I've done it!
Plenty of experience to be gained, you want low viz situations...just hang around the shallow area on a Saturday morning..you'll get your low viz.
You want to experience the cold at 75 feet? They have a platform at 75ft, temps around 45-50 degrees. You can even do a night dive during the day...in the fall...a sulfur layer builds up around 50 feet or so and anything below that is pitch black..I'm talking like a light switch..goes from day to night in a matter of feet. Pretty cool.
Plenty of stuff to navigate too, a small boat, dump truck, rock crusher, fish cribs, LARC military boat, and other various objects.
Ofcourse the website has all of this, but the top side features is what separate this diving location from any others in the area. Air fills, nitrox also at 36%, 4 changing rooms, porta-potties are well maintained, and good food on-site, (quarry is also very close to fast food chains etc).
The owner, Tina, is a very nice woman..I can not say enough good things about her.
In fact, I would be at Haigh this weekend, but I'm going to someplace called Bonaire..I heard the diving there is ok.
