How do you scuba dive in Animal Crossing

You'll only need the Wetsuit to begin diving, but it only exists in Animal Crossing: New Leaf. To get a Wetsuit, you must upgrade from the tent to a house. Tortimer will appear on your town's dock the next day. After speaking to him, the day following his visit you'll be able to take a boat ride to Tortimer's Island (costs 1,000 Bells for a round trip) and wait for a Wetsuit to be stocked.

Unlike your town, you can only buy wares from Tortimer's Island with medals. These are earned through playing mini-games, hosted by Tortimer himself. Each Wetsuit costs 40 Medals to purchase varying in styles. Note: You must be a member of Club Tortimer for the more exlusive wetsuits.
