Having been on a couple of dives where I got to my destination and THEN realised I had forgotten something, I now use a checklist. I thought I would list it here for people to use/plagiarise/amend as necessary. I have different boxes dependant on whether I am doing a shore/boat dive and whether I am staying overnight in the (rather comfy) boot of the car.
