BreakMaster Digital Green Reader
The BreakMaster Digital Green Reader will train your eye to read breaking greens, find the exact breaks on the greens you play and help you lower your score by making more of those breaking putts.  The BreakMaster is a precision electronic device that accurately locates the downhill direction (or true break) of the green, measures the precise angle of slope (from 0.0 - 9.9 degrees) and provides a full readout of both on its LCD display.
