Spirit River now has the ability to process tying materials and build unique flies with both UVF and UVR enhanced materials.  Hence the name UV2!

UVF 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.

UVR or Ultra Violet Reflectance is a UV light that cannot be readily seen with the human eye.  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.  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, Bee’s to find flowers and many fish species use it for mating and to find prey.  The majorities of nymphs found in a stream are males and hence have a natural UVR signature. Our materials help duplicate this.
