Preferred embodiments of the invention comprise an automatic reel (100) capable assisting a user when attempting to unspool a linear material, such as a water hose. The automatic reel includes a control system (200) having a motor controller (224) capable of sensing a pulling of, or increased tension of, the linear material and capable of causing a motor to rotate to unspool the linear material. In certain embodiments, the motor controller tracks the length of the unspoiled portion of the linear material and/or reduces the spooling a speed of the motor when retracting a terminal portion of the linear material. |
