Pocket CO Carbon Monoxide Detector
Simple to use, light, appears to have long life, clips on clothing so will have easy access to cabin air, seems well made, easy to change battery, visible dislay, alarm is audible and visible (especially at night!). Unit comes with excellent instructions. USA made. This unit is far better than the spot CO detectors. It gives an indication of 12 hour exposure, as well as instantaneous exposure. It appears sturdy and should last awhile.
