SensorView Finally! An affordable, quality sensor loupe. We're proud to present the SensorView, an LED illuminated magnifier that will help check your sensor's dust status before and after cleaning. Although the definitive check for dust is still shooting the sky stopped at 22, this tool will help minimize that task by letting you check your dry or wet cleaning results immediately. FEATURES: • Compact size of 2" X 4½" X 1" • A sliding protective sleeve protects the lens when not in use • Crystal clear lens with a sharp, distortion-free view • LED turns on by sliding the sleeve to the full-open position • 3 Duracell alkaline batteries are included   SensorView .95
