Decoying calculator

DETAILED DESCRIPTION OF THE INVENTION Over the years decoys have evolved to suit given sets of circumstances in given areas.
Decoy numbers, styles and arrangements depend on the type game sought in the local area.
The basic guidelines of decoying are herein set out but the specifics for any given species will not be given due to the wide variance therein.
A good source reference for this information is a publication entitled "The Secrets of Decoying Ducks and Geese" which was published in 1982 by Bob Hester who is a professional hunting guide.
Individual decoys must be placed so that each has a purpose and contributes to the total effect.
Certain decoys are used to attract certain waterfowl but more specifically, they should be used to attract waterfowl to a given spot for a productive shoot.
There are two specific reasons for using decoys.
First, they must be so arranged to bring the live birds within shooting range and secondly, they should bring the birds within the angle of fire most advantageous to all shooters.
Although ranges vary with individuals as well as types and loads of shells, the effective range should be the maximum effective range of the poorest shooter.
This must be, of course, determined on an individual basis.
The optimum shooting angle is the direction from the blind most advantageous to all gunners in the blind.
Certain angles give only one or two shooters an opportunity to fire whereas other angles give all shooters an opportunity.
Even with only two shooters, if the waterfowl comes on one side or the other, then only one has an opportunity to shoot whereas if the waterfowl comes either from in front or from behind, then both shooters have an equal opportunity to fire.
This is referred to as the optimum shooting direction angle.
There are two truths known about waterfowl; first, they invariably land upwind or into the wind.
This slows their forward momentum and produces a slower, more comfortable landing.
Because of agility factors, small waterfowl are able to turn against the wind in the last few yards before touchdown while larger birds demand a greater glide distance in making their landing approach
