Last weekend, a buddy and I took a nice lady from Phoenix diving in our local puddle. She was visiting friends for the 4th, found me by doing a google search and sent me an email asking if we could please take here diving.
Why, sure!
Turns out she couldn't dive. Not that she was a bad diver, but that she could not actually manage to start diving. She tried, and we tried to help her, for about 40 minutes, until all of us gave up and she went back to her friends truck.
She couldn't get her equipment sorted out, couldn't get her fins on, couldn't stop her mask from flooding, kept loosing her reg and couldn't recover it, hoses and gages were freely dangling and getting lost, tank fell out of strap, gloves made her hands hurt, couldn't dump her bc air and wouldn't stop fining so she couldn't get down... Endless issues. Plus after 40 minutes she was so hot and exhausted she couldn't have made the dive anyway.
She had a total of 5 dives - all from a dive boat in Cancun during vacation while getting her "weekend cert." She explained that the DM had had set up all her gear for her, sat her down into the tank, and because she couldn't carry the weight, they lifted the kit off her back and walked her to the back of the boat, where they put on her fins for her, inflated her BC, turned on her tank, handed her the reg and slipped her into the water.
She was a very nice lady, tried very hard, but just didn't have the training to dive in our little pond.
