“You have to develop a sense of confidence,” he explained, “which I’m just beginning to see with my son. But so many people have a fear of the water, even if they enjoy being in it. The fear holds them back. Or maybe they get to the bottom and see a lobster, but then they get hurried and become too excited. They work themselves up and start kicking, and before you know it the water’s too stirred up to see anything. So before you can really be successful at lobster diving, you have to learn how to be comfortable with just being down there under the water.”

Once you feel at home in the water, Arnold says catching the lobsters really isn’t that complex. Here’s his recipe for lobster diving success:

• Choose a spot where there’s cover for lobsters (reef structure, coral, rocks, etc.) in 15 to 50 feet of water, but mainly in 20 to 25 feet.
  
  
• Swim along slowly, and look for a lobster’s antennae.
  
  
• When you spot a lobster’s antennae sticking out, insert your tickle tick in the hole until it’s behind the lobster, then bump the lobster’s tail until it walks out.
  
  
• Position your net behind the lobster, then give it a light tap on the head. It’ll use that strong tail to shoot backward and right into your net.

There are, of course, a few finer points to keep in mind. Arnold says it’s sometimes important to not follow the crowds.

“A lot of people concentrate on the reefs,” he said, “which naturally get picked over. Everyone knows to go to the reefs. But don’t get fixated on going where everyone else goes. Those spots that aren’t associated with the reefs – the in-between spots – are the best. A coral head that’s separate from the reef, a rock, maybe a piece of an old boat hull sticking out of the sand and places like that are where you can do really well.”

Another key tactic, which Arnold says few people consider, is following fish to find more lobsters.

“When you see porkfish or surgeonfish, follow them in a non-threatening manner,” Arnold said. “You have to be slow and calm about it, but sometimes it’s all about following those fish. They’ll lead you right to the lobster.”

Once you do find lobsters, Arnold suggests taking things slowly and focusing on getting them out methodically, one by one. Trying to hurry up or failing to concentrate on the task at hand is likely to result in a lost lobster. And aside from the excitement of trying to catch a lobster in the underwater environment, there can be more distractions than you might expect, like a big snapper that swims by.

The appropriate equipment helps, too. If you’re not familiar with diving or simply want to try it out, consider investing in a dive class or hiring a charter captain. If you’re already an experienced diver, you might adopt Arnold’s system. When he and his family dive for lobsters, they use a hookah system, which delivers air to the diver from a compressor on a boat or floating platform via a long hose called a down-line. The system allows them to stay down for as long as three hours without worrying about running out of air. Divers using scuba tanks have a much shorter limit on how long they can spend underwater – anywhere from about a half-hour to an hour, depending on diver experience, dive depth and other factors. As a result, scuba divers often try to hurry things, and the result is fewer lobsters in their nets.

“Be comfortable, slow down, follow those fish and look for the antennae, and you’ll get some lobster,” Arnold said. “It really isn’t all that complex.”

Note: Lobster seasons and regulations vary greatly from state to state. Before planning a lobster dive outing, check the website of your state’s natural resources regulatory agency to find the specific rules you’ll need to follow. A permit or license might be required. Some states limit the equipment you can use, and bag limits do apply. Failure to follow regulations can result in a hefty fine, among other penalties.
