Bought a cheap fiber optic inspection scope and it bit me

Spent about $80 on a no-name scope to check some connectors in a tight spot on a G650. The image was so blurry I couldn't see if the end face was scratched or just dirty. Ended up having to pull the whole assembly to check it on the bench scope, which added two hours to the job. Should have just used the shop's good one from the start. Anyone have a decent budget scope they actually trust?

Wait you used a NO-NAME scope on a G650? That's a serious plane, man. I get trying to save time but that's a huge risk.

You ever actually look at who makes the parts for those big brands? Half the time it's the same factory with a different sticker. If it passes the same tests and does the job, what's the real difference besides the price tag? People get too hung up on names when the function is what matters. A scope that works is a scope that works, no matter what's printed on the side. This idea that only one brand is safe for a nice plane is just marketing fear.

That eighty dollar lesson is why I don't gamble with cheap tools on critical systems. Parkerbrown is right, the risk on a G650 is just too high for a maybe. I see where milarodriguez is coming from about factories, but a brand name means they back up the calibration and the specs with real support. A blurry image isn't just a bad tool, it's false data that can make you think a damaged connector is clean. That function over names idea falls apart when the function itself is unreliable from the start.
