The Marker Tag is mounted inside the detection zone of an antenna to verify continuous operation.
An HDX PIT tag is covered and revealed at timed intervals that are adjustable between 1 and 30 minutes. Any gaps in the detection record will indicate a failure of the reader, antenna or power source.
The circuit runs up to a year on 3 AA batteries. Lithium cells recommended for operation at low temperatures.
The enclosure is NEMA 4 and will seal against wet weather but is not waterproof enough to be mounted underwater. The Marker Tag should be placed in a waterproof bag or a wrap of vinyl electrical tape needs to be placed around the edge to seal the box.
The Marker Tag will not work with FDX tags.
