We are striving to improve all the time and listening to the input from customers.
If there are any questions, please feel free to e-mail us: support@teslong·com
Update: April 20, 2020
- We extended the rod from 21inch to 26inch, which makes the borescope easier to work in 22inch, 24inch, and 26inch barrels, no need to switch from barrel to muzzle to fully inspect bore.
- We have updated the user manual based on common customer questions. If you have any suggestions for the user manual during use, please let us know. Thank you : )
