If you are a computer repair technician, you know how time consuming it can be to detect and diagnose problems on the inside of a unit. Usually, you have to tear the unit and all of its components apart to find a problem and correct it. Borescopes eliminate the need for tearing down the unit, by allowing you to take a look at the inside through tiny openings. You can get a glipse at what is going on inside and diagnose problems without completely disassembling the unit. The instrument can save you a lot of time and effort.
