Target Setting - Radar Guns

Post by smokem »

F. Rules for the use of Radar Guns and Chronographs to set Target Speed

There are two types of radar guns, high-power and low-power. The practical difference between them is that high-power guns work reliably from the 16-yard line and low-power guns don’t.

High-power guns (Decatur, Stalker, most “police radar guns” and similar) are to be used at the 16-yard line. The trap oscillation is stopped, and the target measured is a straightaway. The gun is pointed horizontally. The correct speed for a singles or handicap target is 42 MPH. The correct speed for the right target of a doubles pair is 39 MPH.

Low-power guns (SportRadar, Bushnell, and similar) are to be used at the back of the traphouse and at the level of the top of the traphouse. (Holding the gun higher than that will lead to a target which is too fast.) The trap oscillation is stopped, and the target measured is a straightaway. The gun is pointed horizontally. The correct speed for a singles or handicap target must be a minimum of 42 MPH. The correct speed for the right target of a doubles pair must be a minimum of 39 MPH. When a radar gun is used from inside the house, the correct speed for a singles or handicap target must be a minimum of 44 50 MPH. The correct speed for the right target of a doubles pair must be a minimum of 41 MPH.

A chronograph is to be used as close to the trap as practical and tipped up at approximately the same angle as the flight of the target. The correct speed for a singles or handicap target is 67 ft/sec. To set doubles with a chronograph, set a singles target to 76 ft/sec. and then switch the trap to throw doubles without changing the spring tension.

Note: target speed may be set by distance as above or by speed as determined by a radar gun or chronograph. Target must be set by measured speed or distance.
