Bought A SUBWING for my Brothers wedding, it was by far the best gift they got for their wedding....Later i bought 3 SUBWINGS more for myselfAs for watersports its the most spectacular, low effort, low cost device available.I use it hand held on the beach on 1.5 meters deepth with my 5 years old daugther, and I use it behind a boat paired (two SUBWINGS) with my friends.You can effortless cover a greather area than both snorkling and scooba diving and at very small effort.All you need is a SUBWING a mask and a small boat with 5 HP or more.With some experience and using long towlines/ 30 meters you can easily dive 10 meters deep++. (Use fins incase you loose the SUBWING, so you can surface easyer) and during a short time cover a lagre area many kilometers underwater. Dont use it in Murky waters, as you loose your orientationSoo as for Watersports, its maybe the coolest device around, sayed by a a huge Wake/Surf/Waterports/Diving entusiast.RegardsCarl Henrik Aarnæs, Norway
