Disclosed is system and method for measuring the tension of a tennis net, and, alternatively or in addition, for determining if a service let occurs via the measuring of the net tension. The disclosed embodiments measure a force exerted on the center-strap or the singles stick by the net. In these embodiments, the measured force provides an accurate reflection of the tension of the net.

A tennis net anchoring device and method securely anchors a tennis net center strap to a recessed anchor post on a tennis court surface. The anchoring device comprises a longitudinal, double-sided, unitary body supporting a net-retention member and a ground-retention member. A top portion of the unitary body includes two arcuate T-shaped, net-retention members that retain the tennis net through grommet holes in the net. The net-retention members extend downwardly from the upper end of the middle portion to define an arcuate net-support surface. A lower portion of the unitary body includes two off-set, J-shaped ground-retention members, opposite the net-retention members. The ground-retention members have a ground-retention surface that forms an anchor post insertion channel. The insertion channel enables insertion of an anchor post recessed beneath the court surface. The ground-retention members have free ground ends that enable maneuvering of the anchor post within the anchor post insertion channel.
