On the second day of a cave trip to Florida my CooTwo analyzer stopped working with 'chng snsr' appearing in the O2 field. It seems the solution is obvious, but I am curious as to why it happened. It has been around a year since I purchased it, does it automatically lock out at predetermined date? Does anyone have a way of getting touch with divenav? Multiple attempts to contact them through their website for the last couple weeks have gone unanswered.
