A line sensor deployment and recovery apparatus and system with integrated level-wind. In one embodiment, a line deployment and recovery apparatus with an integrated level-wind, comprising a reel, having an external surface with helical grooves, wherein the grooves facilitate a line; a motor configured to axially rotate the reel; a level-wind shuttle, further comprising: a fairlead configured to selectively feed the line into the helical grooves, or deploy the line from the helical grooves; a shuttle finger configured to align the shuttle with the helical grooves and receive a driving force from the reel's rotations to drive the shuttle; and a shuttle track, oriented parallel to the drum and fixed in a offset position form the helical grooves at an operable track height, configured to facilitate linear traversal of the shuttle along the reel.
