                                    Not just remote area’s, LDS’s that get lax and/or cheap and I was on one respected liveaboard when a crew member didn’t install the filter properly, Captain caught it and flushed all of the tanks.

                                    From caves4me: Analox makes a good CO tester. I carry Co- Pro in my kit. http://co-pro.com/...  not a bad price to pay if you consider it will last probably a day of diving. To late for my Mexico trip. Wish me luck.

                                    it looks like it should be good for a year or two analox recommends the sensor be replaced every two years wonder how much that costs

                                    Depends where you buy the sensor, last time I looked it was between $150 - $170, it’s really a good investment especially when it may save your life.
