Fantasea Line Moisture Detector with 3V Lithium CR1220 Battery

Guard your valuable camera against damage while diving with this Moisture Detector from Fantasea Line. Suited for use in any underwater camera housing with enough space (1.5 x 1 x 0.3" / 34 x 24 x 7 mm), the alarm housing installs with no tools – simply affix it to any side panel with the included double-sided tape. The moisture sensor tapes flat underneath the camera or camera tray. Should any moisture get past your housing's seals, the detector will warn you with a blinking LED and a beeping alarm. The detector is powered by an included, replaceable 3V lithium CR1220 battery.
