The wireless Borecam Pro produces its own WiFi signal which sends super clean and detailed images directly to your phone or tablet. Carefully inspect your bores for wear, throat erosion, tool marks and other rifling damage, as well as copper or lead fouling. The Borecam Pro will fit 20 caliber and larger barrels and is equipped with a 24" rod. In addition to taking photos, the Borecam Pro also takes sharp, clear videos. Photos and videos are easy to store and retrieve.
