I run two sharks tooth dives a summer with Florida West Scuba School and have had good luck wherever they take you. He goes out about 1 to 2 miles and we just dove on April 20 and my son found a $300 tooth just laying on top. Of 12 divers on the boat, all found teeth and they ranged from 1/2 inch up to 4 inches. I think you would have better luck going out with Florida West becuse if you dive off the beach you have to contend with the wave action unless it's very calm. I have heard of some fairly large teeth being found off shore but with the boat you don't have to drag equipment to the beach and back and are not sure if you're in an area where you will find teeth. I have been running these dives for four years now and have not come back disappointed with any dive. Visibility in April is about 4 to 6 feet with water temp about 67 to 73 degrees. In August the water temperature gets to 80+ degrees but the visibility cuts down to about 3-4 feet. You don't need a light but I would suggest a "buddy line" which is line, about 10 feet in length, to keep your buddy around but you don't have to be looking for him while looking for teeth. Another item is a compass to keep yourself going in the right direction of where the best hunting area is located. The captain and dive shop owner, Steve Thacker, is also an archaeologist and can identify anything you bring up. There are also other prehistoric artifacts to be found such as whale ribs, mastedon teeth etc. The trip cost is around $65 and includes two tanks with air, water and soft drinks and a large cookie on the boat. Have fun! George
