The Burris Race Dial elevation turret lets you to write directly on this whiteboard style turret. Using a dry erase marker you can mark each target on a given stage for your specific ballistic data. After the stage you can easily wipe the markings off the dial face and repeat. As an alternative the dial is the same width as cellophane tape so your target marks can be recorded on tape and easily removed as well. If you’re a precision rifle competitor you know exactly what this is and why it’s awesome!
