Develpoed for race engine troubleshooting, the Provision Eagle is based on fiber optic technology and uses a long cable to view hard reach and sometimes impossible to see areas.
The concept is much the same as the scopes that doctors use to look inside a patient, except the cable is surrounded by a stainless steel armored shaft and has a machined-aluminum lighted lens tip to protect it against heat and harmful chemicals such as motor oil. The ProVision will fit into holes as small as 1/4 inch diameter, allowing you to look behind walls, down into drains, or even inside engines without costly demolition or disassembly.
The system is powered by 2 “AA” Lithium Batteries and sports a street price of around $225 (with some careful shopping). That’s not super cheap, but then again it’s something that you just couldn’t even put your hands on for under a grand just a bit ago.
We’re thinking about making the investment in one of these ourselves. How handy would it be to be able to stick this through a spark plug hole and see what’s going on inside a cylinder? Or how about seeing what’s actually stuck in the drain? We can think of dozens of applications, and based on the response to our post on mirrors the other day, we bet you can, too.
