A rusty patch showed me the value of thorough inspection

But what if relying on a boroscope just makes us lazy about real inspection skills? I've watched techs trust the scope too much and still miss obvious spots they could have felt by hand. Those tools are pricey and not always right, giving a false sense of safety. Sometimes the best method is just learning the common rust areas and checking them thoroughly without extra gear. If you always depend on a boroscope, you might never develop that eye for detail. Honestly, pushing for more tools over better habits seems like a step backward.
