摘要:
A weight retraction device for use with a waterfowl decoy includes a housing having a spool rotatably coupled thereto. A weight is attached to a line that is wound around the spool. Rotation of the spool in a first rotational direction causing an unwinding of the line from the spool to cause the weight to extend away from the housing while rotation of the spool in a second rotational direction causing a rewinding of the line back onto the spool to cause the weight to retract back towards the housing. A power spring is configured to urge the spool to rotate in the second rotational direction. A lock release mechanism is configured to normally be in a locked configuration for preventing an undesired rotation of the spool in the second rotational direction. A manual actuation of the lock release mechanism releases the locked configuration of the lock release mechanism.
