Ran into a guy who still sets his offsets the old way, found out why

I was helping out at a friend's shop last week and this older operator kept resetting his tool lengths by bumping the tool to the part instead of using a presetter. He said he gets repeatability within two tenths that way and doesn't trust the presetter after a crash messed up his numbers once. Does anyone else run into situations where the old school method actually beats the newer stuff or is this just a stubborn thing?

Heard a guy at a trade show swear by the bump method too. Said the presetter is great until a tool holder gets a nick you can't see with your eye, then you're chasing tenths for an hour.

Man totally hear that lol @white.alex makes a good point. I had a buddy who ran a job for a month with a presetter and everything was golden till a tiny burr on the holder threw his Z off by three tenths. Bump method caught it right away while the presetter just said it was good.
