Twenty-six years of building the best sights money can buy. That's what you get with Black Gold. Mike Ellig President, Black Gold, Inc. Inch Wheel Adjustment makes dialing it in easy! learn more PhotoChromatic Shell... It Turns Purple! learn more SkyCoil Technology Black Gold's exclusive SkyCoil™ Technology gathers 300% more light for brighter pins while patented PhotoChromatic Technology automatically manages pin brightness during the day. No other bowsight offers either. Black Gold gives you both! Most bowhunting opportunities happen early or late in the day when game is more active and light is low. This means pin brightness is not just important, it's critical! Pins that are 20% brighter Independent tests show that the pins on a Black Gold bowsight are 20% brighter than the pins on the next brightest bowsight. This means you'll be able to see the pins on a Black Gold when the pins on other bowsights have faded away! Exclusive SkyCoil™ gathers 300% more light! The coiled fiber optics on a Black Gold reside in the SkyCoil which is mounted on the top of the sight where there is more available light. This system is 300% more effective at gathering and transferring light than other wrapped fiber bowsights.
