How to Repair a Bushnell Holosight

The Bushnell Holosight is an advanced holographic firearm sight, generally mounted on shotguns or rifles. This device uses a laser to produce an illuminated reticle hologram inside the eyepiece, but doesn't employ any magnification properties. As with all electronic devices, problems can arise from time to time. Because the sight is used outdoors and is exposed to weather, a common problem associated with the Bushnell Holosight is battery trouble typically due to corrosion. Repairing the Bushnell Holosight can be accomplished with little difficulty.
