Talking about tough accomplished skilled go-getter scuba divers and you have to include Malena Sharkey in the conversation. Here she's with me this morning checking out the survivability of the Type 2 Apple Watch at 86' underwater on one of the Palencar sections off the west coast of Cozumel, Mexico (it took a licking and kept on ticking).

Tech: Nauticam underwater housing with 230mm Zendome from Reef Photo & Video in Ft Lauderdale. A Canon EOS-5D Mk IV and 16-35mm f2.8 II inside. Lighting by my trusty dual Ikelite DS-161 Movie/Strobe lights. -- with Nauticam, Nauticam USA and Malena Sharkey.
