The Snap-on New Generation True Digital Video Borescope, No. BK6500, helps technicians to view difficult-to-see places when tackling a repair. Whether behind the engine block or inside the radiator to check for corrosion, the BK6500 features dual-image lenses for straight ahead and 90-degree angle viewing. Digital video images are stored to the internal memory or SD card, and the video recording and playback capabilities provide quick, easy referencing when completing a job. The 4.3" diagonal LCD screen has a 40 percent larger viewing area than competitive units and the previous model, according to the company. Powered by a rechargeable Lithium battery, the BK6500 is equipped with a USB port to transfer data and comes with a two-year warranty.
