In 2019 the NCAA approved a men's lacrosse 80-second possession shot clock and women's 90-second possession shot clock. The NEVCO portable segment timer is a convenient, easy-to-use, portable segment timer that is perfect for games and practice. There are up to 40 programmable segments on this timer. It also includes a portable hand-held control that allows programming independent of the display. The lithium ion battery allows for 6+ hours of operation. Even though the shot clock has only been approved for college, most high school level coaches will be incorporating the shot clock in their practicies to prepare their players for the next level of play. This is the perfect portable solution for on field shot clock training.
