Air gun shooters have been concerned with scope cant for years. Using a bubble level helps eliminate scope cant but most bubble levels are placed on the gun's dovetail or scope rail or even screwed into the base of the mount. But ScopeLevel uses a unique, creative way to using a bubble level which is to use scopes rather than the air guns.  ScopeLevel product are available for use with 1" or 30mm scope tubes and are attached to the scopes tube using a scope ring. The bubble level then can be raised up in the shooting position or folded down onto the scope when not in use. What is so creative about the bubble level is that when the unit is raised up for shooting, simply looking into the scope makes the bubble level to appear as though it is perched right on top of the eyepiece. The shooter can quickly correct the cant without having to move one's eye from the scope. This is a very creative and useful product for all pellet gun shooters.
