[Looka]

I Am going on a diving trip this summer and I was advised to buy a deco-bouy and a reel, which I have done - but I have never used such a thing before..

Is it sent up from the bottom or near just before you reach your deco stop depth?

Wont the lift from the bouy drag the diver towards the surface when he uses the reel to send it up?

It would be an enormous help if someone could answer the questions and give a fast instruction in how to safely use a deco bouy.
