I'm about to start researching into a 4 gas meter as I recently encountered bad gas that the o2 meter wasn't able to alert me of. But currently mine is a KKmoon unit, UPC: 787414708660. It was available on Amazon but it looks like the listing was removed. The subreddit r/TheForgottenDepths has some good resources for quality models as well!
Loved the mine exploration! What O2 monitor do you use? I need to pick one up myself
