Gunstar's Mini Black Eye Blinder will keep you focused on the target. Clip this to your hat, alongside the eye you're not using for aiming, so that your vision is totally focused through your peep. The black blinder is great for archers who don't want to see anything on the periphery.

• Clips to the bill of a hat
