Recommended borescope

Sorry for the rushed English guys.  Differential is the best.  Borescopes enhance your inspections when you have shaky readings and need to understand what is happening before you take it all apart.

I have a couple of borescopes, and each has something it does well.  The first one I bought was a Milwaukee 3150-20 with a 5mm camera.  The tip does not articulate but the wand is stiffer than most and you can kind of pre-shape it to go where you want.  It’s great for looking deep into a cavity such as a wing or tail section because the camera wand will hold a shape and support itself as you advance the camera, so you don’t need a guide tube.  It also has an 8mm camera for a larger field of view (sold separately). It’s not a great cylinder borescope, but I end us using it the most for other types of inspections, or to find a part I dropped into a difficult area. 

Later I bought an ATS Voyager, which was twice the money but has two way articulation and video out for real time viewing on a larger screen.  It handles/controls very well and is superior in a cylinder or other areas where a very flexible, articulating camera is important.  These are not just engine tools, once you have one  you end up using it for all kinds of things. Cylinder bores of course, but you can also inspect deep into small hard to reach areas, and you can get a closer look at items you may otherwise only be able to see at a distance.  

With my long history of "big iron" aircraft engines, I am disappointed that my trusty VA-400 borescope head is unable to turn 180 degrees to view valve faces within confines of my 915iS. Is there a better borescope to be used with Rotax engines?

I have the ATS Voyager and it works very well, and has a unique set of extra led lights to the side of the probe.  It won’t articulate 180 degrees in a single direction, it’s 240 degrees total, so about 120 each way. But it also has a screw on 70 degree mirror end, and with that you get more than 180 degrees total with the mirror and articulation combined.  I also end up using the digital photo option more than I thought I would.  Once downloaded to the computer you get fantastic detail.  

Very interesting, and pricey (at least 4X my Vivida cost).

Is this an Aircraft Tool Supply built device?

Got a couple sample Rotax valve views to share?

How easy to twist the viewing angle?
