No., Just sight your scope in.. set it to zero ie dead on @ 30yrds or whatever you set your scope up to shoot dead on at. Mines 27yrds for my .177's and 25yrds for my .22.
You want to be as close as you can to the paper, if you can get the muzzle touching then it'll be most accurate. I did mine into the ground as a safe backstop.
Shouldn't matter being a Springer
Hope this helps

Some would say that it's the only accurate method to use with a springer.
Springer muzzles move around a bit through the firing cycle (vertically and horizontally) but you're only really interested in where the muzzle is relative to the original line of sight when the pellet exits. The 'tin-foil method' - as this is known - gives you exactly that.

You'll love the reticle feature on chairgun then.. I've impressed a few "point & press" shooters with the range finder & a very accurately placed 50yrd "first shot"!.
Tis great having it on your phone with a range finder when your playing in the field
