This monofin is the closest you'll get to becoming Aquaman.
Don’t just swim with the dolphins. Swim like one. The engineers behind the Lunocet monofin allow you to do just that. For somewhere in the $1,000 to $1,800 price range, you can upgrade from those cheap plastic feet fins to some hi-tech biometric flukes that will give Michael Phelps a run for his money. Apparently, it’s so powerful that you could pull a Free Willy over a jetty with it. This buoyant piece of silicon, carbon fiber and titanium weighs just 2.5 pounds out of water and can propel you up to 8 miles per hour. It's made for scuba diving but if you just want to cruise the coastline in it then, hey, do your thing. We definitely could see James Bond in one of these. Either way, it’s okay to be a merman.
