Teslong Borescope

I ran some errands, I found a series of boxes on the porch. I got an ammo shipment, some cleaning stuff from 20/20 concepts (patchworm) and my new Teslong borescope.

I love my original Teslong borescope, but I bought a unit that needs to be run through a laptop. Which make any remote usage very hard. This unit is the 45” flexible unit, that has both its own viewing screen and the cable for the ability to be used with a laptop.

I fired it up and checked the bore on the newer Ruger Precision Rimfire, it looks great. I can see where the handheld mobile unit will be a lot more user friendly than the laptop based unit.

I looked at those cheap Bore Scopes and saw few advantages. I purchased a Lyman Digital Bore scope that has many advantages over the cheap stuff. I can use it at the range on Battery Packs like I charge my cell phone. I can Capture to memory card and then transfer to my desk top. There's a scale on the probe, so I can tell exactly where any fouling or damage is located. Good clarity on monitor as well as my Desk monitor. Well worth the investment.
I've had several borescopes, the Lyman Digital, an Oasis Scientific, a Teslong, and have access to a Hawkeye optical borescope.

The Lyman was the first generation with only 320x240 resolution and the monitor was intermittent right out of the box, then the buttons on the monitor quit, Lyman replaced it, but the replacement had image quality issues, so I returned it and Lyman eventually refunded my money.

The Oasis Scientific is the GB-460 model with wifi connects to my iPhone, or iPad wifi with no problems or my Windoze 10 laptop or desktop using the Windoze Camera driver and captures images or video. Older versions of Windoze will need the free software from Oasis. The GB-460 can also be connected via USB. Mine was on sale for $199 with the wifi bundle when I purchased it.


I bought the Teslong because I needed a semi-flexible, small diameter borescope for some non-firearm related projects. I think it was $50 when I purchased it. It is strictly USB, but it plugs into the Oasis Scientific wifi adapter and works fine with it. Using the wifi adapter I capture images or video direct to my iPhone or Ipad. With the USB, I capture images and video directly to disk using the Windoze camera drivers.


The Hawkeye is better than the digital borescopes, but not $600 better and isn't flexible.

Lyman has a new 'Pro' version for $350, but like the earlier generations it uses proprietary parts, so your stuck with it and has no USB. It requires an app to work with iOS or Android, it also doesn't work with Windoze according to the Lyman website. It now has a 720p camera, same as the Oasis and Teslong.

For less than $50, the Teslong works very well and is more than adequate for any hobby shooter. Mine is 2 years old and has held up fine to some fairly heavy use in less that ideal conditions in dirty, oily, hot engines.

The Oasis works better as a gun barrel borescope than the flexible Teslong. Teslong also sells a rigid version that looks very similar to the Oasis for around $75. The wifi adapter requires an external USB power source, either a PC USB port or a USB power cell. The price for the borescope and wifi adapter is currently $249, but they regularly run sales or coupons.

I think mine was right at 38.00 shipped..The big advantage I see over the others is the price..The Teslong to me has amazing clarity..It is definitely worth the money..I will not pay five times and more for the same movie:)
Yes, but does the more expensive movie theater have more comfortable seats? :D

Just kidding!

I forgot to mention that Oasis Scientific sells the Wifi adapters separately, if you already have a USB borescope and want to use Wifi for an iPhone or iPad. There may be cheaper versions around, but doing a quicky search, most were male USB to add Wifi to a laptop or tablet. These are female USB receivers.

$115 for one with a rechargeable battery.


$110 for one that requires an external power source.
