The only way you're going to catch a fast running thief, is with a faster running meth head. If you can get one of those when you pick up batteries you are set for the sting.
If your scuba diving have a partner, if your snorkeling have a floating dive flag. It will be your best buddy if you get tired. Also you can tie your shells on it to.
For sh!ts and giggles, any one have any of the exploding ink packs the bank puts in the money? Leave him a load pair of shorts on the beach. The ink takes a long time to come off.
If there is someone walking down the road with makeup on breathing out of a snorkel brushing their hair and carrying a beach bag with owls on it. I will bet $100 US. thats the person who took the car.
