Okay...got a chance to do a little connectivity testing with the NTG100H scope Teslong sent me to evaluate.
I was able to connect easily to two
very old Windows laptops (Windows XP and Windows 10) by just using their resident camera suites and selecting Teslong in their settings.
On my Samsung S9, I got a message to connect the camera even though it
was connected (Teslong HD Camera app...which had worked for my original Teslong scope). Switching to the Endoscope Camera app available for free in the Play Store (
Endoscope Camera Novotech Industries Limited) took care of the problem and actually works a bit better with my original (flexible cable end) Teslong too.
NOT THE HD VERSIONS.
Though no mention is made of its connectivity to chromebooks. I was curious and pleasantly surprised to find that it worked using only the resident camera app on the device. Just connect the scope, open the camera app (the one for the computer camera in the lid) and click on the symbol in the lower left corner to toggle between the computer camera and the Teslong. The symbol does not show unless the scope is plugged into a USB slot.
First impressions are very good. The probe, while a bit short for most of the barrels we like and will require viewing from both ends (about 21 1/2" - won't be surprised if Teslong offers a longer version later), feels quite solid and well made. The sliding marker is a nice touch and the handle is slim enough that it should clear all except extremely high combs. The whole scope comes in a very rugged tube with dense foam tubing further protecting the rod portion and had three mirrors in a small package. Connections are the same as on the original model - USB, USB-C and mini-plug (old-style Android phone charger connector). The USB-C is provided by the pre-installed adapter on the cord. USB is available by removing the pre-installed adapter and the old mini-plug is nestled inside the USB and accessed by flipping one side of the USB socket up revealing the mini. Very clever design.
I actually see uses for both versions: The original is perfect for very long barrels, case inspection, chamber and recess viewing and etc. due to its flex.
The rigid version is best (in my opinion) for barrels where you might want to reference exact spots in a barrel where attention needs to be given (sliding marker) and can be better at either controlled rotation of the mirror or staying straight in a bore due to its rigidity.
I will test it out on actual barrels in the coming days as time permits. I have found that retirement is busier than when I was working!
