Claimed to increase your shooting in twilight hours by 15 minuites, the Bisley Scope Maximiser is a must have for any hunter or FT/HFT shooter. The scope maximiser is designed to optimise the benefits of your scope by forcing the eye to "tune in" and line up to the scope without the distractions of light in your eye relief.

The light in your scope tube will always be less than the surrounding light, by obliterating all other light sources your eye will adjust to make maximum use of the light in your scope. It is the same as looking into a darkened room, within seconds of stepping in the room your eyes adjust and your eyes see much more than you could from the outside.

The Bisley Scope Maximiser will fit 98% of scopes and suit most shooters including left-handers as well as those who use glasses.
