$250 for an especially useless POS that in no way contributes to your diving. I'm biased because I had one fail on a deep wreck dive in NJ. Pulse was suddenly reported as 250BPM and the computer locked up. Then had to convince the captain to let me do a second dive despite the computer locking up.Divers-supply has an upgrade available ($250USD) but they won't ship outside the US. Scubapro is notorious for that sort of thing.
