This solution for Apple iPad and iPhone (IOS device) owners. It features the new Vividia VA-980 Flexible Borescope (V5), plus the W03B WiFi adapter to wirelessly connect your borescope to your apple device. 

The VA-980 Borescope features a semi-rigid (also called "obedient") shaft that can be bent and contoured around obstacles to access difficult areas. The tip can be made to continuously articulate a full 180 degrees via a plunger on the handle. This allows you look straight ahead (0 degrees), perpendicularly (90 degrees), or even backwards (180 degrees). And at only .33" (9.5mm) diameter the probe will easily fit into a spark plug ports, allowing you to perform full inspections of cylinder walls, piston faces and rings, and the intake and exhaust valves. The HD resolution (1280x720) camera auto-focuses from 1.57" (40mm) to 16" (400mm). And it's LED tip lights serves to clearly illuminate the inspection area.

The addition of the W03B WiFi controller provides both wireless capability and a battery power source for your borescope. So, all you have to do is simply log onto the W03B's signal, load up the camera app (a free download) and start inspecting.
