Double dyed select CDC feathers will give your flies an edge on the water! Beautiful natural colors from light to dark will allow you to create the perfect fly. Learn more about the UV2 process below.ย
Spirit River now has the ability to process tying materials and build unique flies with both UVF and UVR enhanced materials.ย Hence the name UV2!
UVFย is the FLUORESCENT wave length in bright colors we know and see in materials or paints which allows fish to see flies and lures at a much greater distance. A huge advantage in many light and water conditions. Remember, if a fish cannot see your offering then he cannot eat it.
UVRย or Ultra Violet Reflectance is a UV light that cannot be readily seen with the human eye.ย However it can be seen and used by most insects and animals. They have different rods and cones in their eyes and can see far more UV wavelengths than a simple human eye.ย The concept is similar to a dog whistle humans cannot hear yet dogs clearly can.
Females of most species recognize the natural UVR signature of males. Mayflies use it to find mates, Beeโs to find flowers and many fish species use it for mating and to find prey.ย The majorities of nymphs found in a stream are males andย hence have a natural UVR signature. Our materials help duplicate this.
