Teslong Borescope Kit is combination of a NTG100 USB Borescope and an NTS500 Industrial LCD Monitor.  The display monitor has a 5 inch1280x720p LCD tempered glass screen. Rated to IP67 and powered by a 3500mAh lithium-ion rechargeable battery. The NTS500 is an advanced stand alone device. It can record JPEG images and MPEG-4 videos to a 32 GB Micro-SD card.  There is microphone to add voice overs to any video you take of your bore.

Housed in a sturdy hard plastic box, the Teslong Stand Alone Borescope Kit is a robust solution.  This is a dedicated borescope with a single camera, optimized for the purpose of inspecting rifle bores.

The lithium-ion battery charges using a micro-USB cable and power source in approximately 3 hours, yielding 3 hours of operating time.  There is a convenient LED light on the display unit which is very useful for rifle inspection.  This is a perfect combination for those who clean and store their rifles in a poorly lit armoury.

The Borescope itself has a working length of 47 inches (117CM) making it suitable for even the longest Match Rifle barrel.  The diameter is .20 inches (5m) which works with .22 rimfire calibre and up.   The Teslong borescope will still attach via USB or Micro-USB to your android smartphone or PC making this combination very flexible.
