Replace or rebuild 17 year old Atomic M1 reg?

[BoltSnap]

Thanks again for your feedback guys! Very helpful. I will send it to Atomic and have them do a thorough service since it's been a while.

This is the beauty and value of Atomic regulators, durability, performance, reliability and very long life cycle with upgradability to latest version of the regulator.

Quite exceptional really

If it is DIN, I prefer the older all brass thumb wheel construction to the newer plastic ones. Feels nicer in the hands ¯\_(ツ)_/¯

Everything else was already well covered by others. I’d personally just get it serviced and keep diving it.
