Teslong NTG500H Borescope

with No Comments

Teslong sent me their TS NTG500H rifle borescope kit to test and evaluate. The package comes in a long padded box containing the ≥26″ long wand/probe, a USB-C charging cable, a USB-C video cable, a USB-A/Mini video cable, a display monitor and video recorder (with a 32GB SD card), and a set of 4 right angle adapters for various rifle calibers:

(5mm) diameter for .22 caliber & larger
(6mm) diameter for 6.5 Creedmore & larger
(7mm) diameter for .30 caliber & larger
(8.5mm) diameter for .38 caliber & larger
(12mm) diameter for .50 caliber & larger

The display monitor also functions as a recording device able to take still photos and video in 720p. Using the USB-A/mini adapter cable, you can connect the wand directly to a tablet or PC. I attempted to test it on my Samsung S21+ phone but was greeted with an Android warning message saying USB video was disabled, which was more of an issue with the 3rd party endoscope App I had downloaded than this device.

The wand/probe has .20 cal diameter allowing it to be used with tight bore .22cal rimfire rifles. The wand has etched inch markings along its length and a white washer plug that help you mark the depth of the probe. This helps you more easily note and return to a specific area of interest in your barrels such as deposits, burrs, and cracks. The rigid wand does make controlling the direction of the probe much easier than non-rigid endoscopes I’ve used.

The video taken with the display was quite good, comparable to other borescope/endoscopes I’ve owned. Not having to download dodgy 3rd party App software on my phone is a plus. It has a built-in rechargeable battery and even a built-in flashlight should you need it.

The unit is a bit pricier than similar borescopes or Teslong’s non-rigid endoscopes. I would have liked a 1080p camera but this may be unnecessary since the tiny sensor at the end of the probe may not actually record details higher than 720p, a larger 1080p file may be over-sampling.

A common issue with new users are complaints of an out-of-focus image. This borescope (and many others this small) are not an auto-focus camera. The focus must be manually adjusted by the user by turning the right-angle mirror to the appropriate number of turns onto the wand. This will vary depending on the size of the barrel. The user must adjust the mirror and lock it in place with the tiny locking ring at the end of the wand. One revolution either way could mean the difference between a blurry mess and a tack sharp image.

Not only are they useful for cleaning and maintaining your new firearms but could be invaluable in evaluating a vintage or collectable C/R rifle. Seeing the condition of the inside of a barrel could mean the difference between paying for Field Grade and paying for Display Grade.
