Mark 5 dive computer looked way too cheap. I was wrong.

Buddy on a pipeline job near New Orleans swore by this little backup unit. $180. I figured it'd crap out after a month. He let me borrow his during a deep inspection. 110 feet. Stabilized right away. No glitches. No lag. Now I always bring a backup. Anyone else run a cheap secondary that surprised them?

...and how deep did you actually take it? I mean, the spec sheet says it's rated for 130 feet but I've heard mixed things about the pressure sensor at that range. 110 is fine, sure, but what about a real bounce dive to 120 or 130 for a few minutes? That's where I start wondering if the cheap guts are gonna hold up or just start going haywire.

Yeah, the "cheap guts" thing, I mean... a buddy of mine took one of those to about 115 feet in a quarry once. At 90 it was fine, but when he went deeper the numbers started jumping around on the screen, like it was confused or something. He said the display flickered and it showed him at 130 then 110 then 125 in like ten seconds. He came back up and it was still reading 40 feet when he was on the surface, so definitely not a reliable thing past a certain point.
