BACKSTROKE FLAGS - Pennants that are suspended over the width of each end of the pool approximately five yards/meters from the wall that notify backstroke swimmers that they are approaching the end of the pool.

BUTTON- The manual timing system stopping device that records a back-up time in case the touch pad malfunctioned. The button is at the end of a wire, plugged into a deck terminal box.

CHAMPIONSHIP MEET - The meet held at the end of a season. Qualification times are usually necessary to enter meet.

CHECK-IN - The procedure required before a swimmer swims an event in a deck-seeded meet. Sometimes referred to as positive check in, the coach will mark each swimmer's name on a list posted by the meet host. Once a swimmer is checked in they must swim the event or they will be scratched from his/her next event.

CIRCLE SEED - In a meet with both preliminary and finals sessions, the fastest three heats of each event in prelims is circle seeded. That means the fastest swimmer is in the center lane in the fastest heat, the second fastest swimmer is in the center lane in the next-fastest heat, the third fastest swimmer is in the center lane in the third-fastest heat. The fourth fastest swimmer will swim in the fastest heat next to the fastest-seeded swimmer. The fifth fastest swimmer will swim in the next-fastest heat next to the second fastest-seeded swimmer, and so on until the three heats are filled up. As opposed to the normal slowest to fastest seeding in the rest to the heats (used in a Timed Finals format).

LENGTH/LAP- Technically, a length is once across the pool; a lap is across and back. However most coaches use the terms interchangeably to mean simply once across the pool. Thus, 4 lengths in a 25 yard pool would be swimming across the pool 4 times, totaling 100 yards.
