Product Information
The Fantasea FA1 Moisture Detector is a leak-warning accessory that installs inside an underwater camera housing to alert the user with a flashing LED and an audible alarm the moment moisture is detected. It consists of an alarm unit and a separate moisture sensor unit connected by a thin wire, and it runs on a replaceable 3V Lithium CR1220 battery that comes included.
Who it is for
The FA1 is for underwater photographers and videographers who want an early warning of a possible seal failure while shooting in a camera housing. It is designed to be installed inside any housing that has sufficient internal space for the alarm unit without interfering with the housing's watertight seal.
Key details
- Alarm unit measures 34 x 24 x 7 mm and mounts to a housing side panel using an included double-sided installation sticker.
- Moisture sensor unit installs just under the camera or camera tray inside the housing and connects to the alarm unit by a thin wire.
- The system is very sensitive: when the sensor detects moisture, the LED begins flashing and the alarm starts beeping.
- Powered by a 3V Lithium #CR1220 battery, which is replaceable, non-rechargeable, and included with the unit.
Compatibility and sizing
The FA1 can be installed inside any housing that offers enough internal clearance for the 34 x 24 x 7 mm alarm unit, provided the installation does not compromise the housing's watertight seal. All components should be handled carefully during installation.

Frequently Asked Questions
How does the Fantasea FA1 Moisture Detector warn me of a leak?
The FA1 uses a moisture sensor unit installed under the camera or camera tray inside the housing. When the sensor detects moisture, the alarm unit's LED begins flashing and an audible alarm starts beeping, alerting the user to a possible leak during use.
What battery does the FA1 Moisture Detector use, and is it included?
The FA1 operates on a 3V Lithium #CR1220 battery. A replaceable, non-rechargeable CR1220 battery is included with the unit, so it is ready to install without purchasing a battery separately.
Will the FA1 Moisture Detector fit inside my camera housing?
It can be installed inside any housing that has enough internal space for the alarm unit, which measures 34 x 24 x 7 mm. Confirm your housing has room for this unit without interfering with its watertight seal before installing.
Does installing the FA1 Moisture Detector mean I don't need to check my housing seal?
No. The FA1 assists with detecting moisture inside the housing, but installing it does not eliminate the user's responsibility to validate the housing's watertight seal before and during the dive.
