Sorry to burst the bubble - but what an absolute load of Crap !!
Im seein it for what it is and it does not inspire me to want to get a tiny bit of air with restricted freedom by being tethered to a drag anchor..
if you want airtime go Paragliding
if you want to kitesurf and trick/megaloop/surf go kitesurfing
Adrenalin junkies we are - and being restricted in flight just doesnt cut in in my book
The water jet pack is the buzz if you really lookin for a drag anchor
Back to the drawing board dude
