Usage

Through the use of a supplied cable the monitor
can also be used separate from the hand grip.
The endoscope is switched on with the rotary knob in the hand grip. This knob also provides a continuous brightness adjustment for the camera illumination. With the aid of a few buttons underneath the monitor the user can adjust a few settings via a menu, such as date/time, language and acoustic feedback during operation. You can use the buttons below the screen to digitally enlarge the image, rotate the image in 90 degree steps, store a screenshot of the image or make a video recording. There is also a settings menu where, among other things, you can select the photo and video resolution. If you select 720p, it appears that the images will be up-sampled in software (since the camera has a resolution of only 640x480 pixels). This doesn't really generate any more information, but it can improve the appearance of the image somewhat.
 
A 2 -m l3 ft.) long cable with built-in camera
is available separately.

The operation is, after a little use, easy to master and the quality of the image is very usable. It is a pity that the resolution of the monitor is so low, this makes the image rather course (a little browsing on the internet revealed that this is a typical resolution for endoscopes in this price bracket). The camera works well. Even in low light it continues to generate an acceptable image, although noise starts to become visible. This is much improved when the LEDs are switched on.

I found that a tube length of 1 m is more than sufficient for practically all situations. It is a considerable length and you have to be careful how you bend the tube into the desired shape and how you move it in combination with the hand grip. In the beginning you will easily look past the object that you're trying to look at. This requires a little practice. For those who really want to operate over a bigger distance with this endoscope, there is also an additional camera tube with a length of 2 m available. This has to be sufficient for all applications. Finally a tip for prospective users: Use a set of good-quality alkaline batteries for the power supply, because the device draws a continuous current of some 350 to 400 mA when the LEDs are off. You will then be able to continuously operate it for a few hours.

This PeakTech endoscope is a handy instrument that will be useful for many jobs, certainly not just electronics related.
