The Blind Judge 3 also known as just a Judge 3, is a powered raley with a backside 360 handle pass. This is a great move to do in flat water or off a kicker in the surf. A great progression to the Judge 3 is to learn Raleys, then Raley to Blind, then Blind Judge. Once you have your Blind Judges down (a Raley with a 180 handlepass landing toeside) ,you'll be ready to step up to the Blind Judge 3.
You'll need some more air and speed to get the Blind Judge 3, but we'll let the videos above explain the rest.
Go downwind and unhook, keeping the kite at 45
Pop a raley that is big enough for you to have heaps of time in the air. You need twice as much time as a Blind Judge.
Tweak your raley so that your board goes vertical, on the opposite side to which you are wanting to spin. This is called a rewind, and it'll help you do a fast rotation due to the way you are effectively coiling up- giving yourself a greater range of motion when you unwind into the 360. The Tobias video above shows this nicely. Wait.. so your actually having to rotate more? Yes, but you'll go way faster with the rewind. Trust us!
Pull the bar in towards your front hip as you reach the apex of your rotation. As you do so, let your legs come back underneath you. This will help you get the bar closer
Turn your head to look over your back shoulder, intiating the rotation. Let go of your back hand as you do this
Focus on your body making the rotation rather than passing the bar. We say this because: 1) You're more likely to actually rotate, rather than getting stuck halfway because you're too besotted with the bar 2) Your bails will be way nicer if you land facig the kite, rather than catching that heel edge and coming in backwards
Spot your landing and let you legs follow you around. Try to keep that bar as close to you as possible. If you've popped correctly, this isnt too difficult as you should have enough slack
As you come back around to heelside, pull that bar really hard into your hips, this will help complete the rotation and give you an extra bit of balance
Get your spare hand back on the bar to help your landing, bend your knees to absorb impact and make sure you ride away downwind.
Hook back in, bar spin and ride away. You're a boss.
