Video Inspection System
The PalmScope from General Tools and Instruments is a full-featured, pocket-sized video inspection system built to survive the harsh environments of HVACR maintenance and plumbing. The PalmScope’s clamshell design allows the camera-tipped probe to be coiled safely and conveniently inside the device. In addition, it can be operated with one hand, leaving the other hand free to use tools. Retailing for less than $150, the PalmScope has just five control buttons—power on/off, brightness up, brightness down, video zoom and video flip—and is very user-friendly.
