Not to sound like an idiot but what exactly is a fur tracer?
If I understand correctly they are pieces of fur that attach when you push the nock into the arrow shaft. They are brightly colored and allow you to better see the shot.
They work best when wrapped behind the fletching but some guys put 'em in front, just for looks. Personally, whenI used them I like to put them right behind the fletches rather thanclose to the nock as shown in this pic.
T U got them orderd ,info on somethings is hard to come by,just so glad that i found this forum when i did,fur trachers have been around a long time but somethings get left in the past.
