TIL my mixed gas analyzer was giving false readings for 6 months
I always trusted that thing because it cost me $800 new back in 2019, but after a nasty headache during a 120 foot dive off Port Townsend I decided to test it against a buddies handheld unit. Turns out the sensor was drifting and showing my nitrox was 32% when it was actually closer to 28%, which is a huge difference at depth. Anyone else ever get bit by gear that seemed fine but was slowly failing on you?

A buddy of mine had something real similar happen with his dive computer a few years back. He used it for like 18 months, never thought twice, until he got a bad case of the bends after a routine 100 foot wreck dive in Lake Michigan. He sent the computer in for servicing and the shop said the depth sensor was off by about 10 feet the whole time, meaning he was actually deeper than what the screen showed. He figured it was fine because it always seemed to work right, but that one little drift almost did him in. It's crazy how a small error you don't catch can spiral into something nasty.
