Falconry & Raptor Calculator
Professional equipment fitting, fitness metrics, and hood sizers.
Hood Dimensioning
Estimated Hood Pattern Sizes
Hood Clearance & Block Ratios
A properly fitted hood must never contact the raptor’s sensitive cornea/eye area, and should seal completely over the beak opening without interfering with respiration.
