The present invention provides an anchor alarm device which is a manually deployed weighted device attached to or near the anchor which signals to device equipment at water-level. The device detects the movement of, or physical force generated by, a dislodged anchor. When deployed, a component of the anchor alarm device rests adjacent to or as part of a seated anchor at a distance predetermined by the tolerance of the secondary rode. The secondary rode connects the device directly to the anchor, or near the anchor on the primary rode. Upon displacement of the set anchor, in excess of the secondary rode, the device alerts the user. The device utilizes sensor monitoring inside of a housing component to detect a force indicative of anchor displacement. This detection triggers a signals emission which alerts the user of the change in position. In cases wherein the anchor is not immediately retrieved, device re-arms autonomously and stops emission of the alarm signal until the next anchor displacement. The system communicates with signal devices on board or deployed near the anchoring vessel in order to alert the user.
