A reel has a spool member on which the linear material is spooled, an electric motor that rotates the spool member, and a controller that controls the operation of the motor. The controller monitors an unwound length of the linear material based on sensed rotation of the spool member by one or more sensors. The controller causes the electric motor to wind the linear material around the spool member, for example, upon detection of a pulling force on the linear material over a pull distance within a predetermined range, but, for example, does not trigger the winding of the linear material if the pull distance is greater than the predetermined range. The controller can cause the electric motor to stop winding of the linear material upon detection of a force on the linear material that holds the linear material in place.
