Spotmark II is today's replacement for the old table spot sticker from "Tefco". These black table spots are the cause for "Dud" opening breaks. Why? Sometimes the rack is loose- caused by the "master spot sticker" moving the front ball, to wander and come "loose". How? Order a Spotmark IIand throw away those stickers NOW. Spotmark II is mounted above your table and replaces the sticker with the pinpoint of a laser without ANY PHYSICAL marks to your table. The result ZERO defects in your game from start to finish from an external source. More to the "point" we are to blame for a poor shot when spotmark2 is in the game. EASY to install, no wires, just three screws into the ceiling (provided along with the template/plate).
Spotmark is battery powered and turns on with your pool light. Is held up with magnets and easily aimed.
