Today's Stimpmeter Reading: 10'9"

Some may argue it is on the slower side but a great speed for daily play.  In fact, the reason for the decrease is simple.  With the heat and humidity we've been experiencing, I've backed off double cutting and grooming.  Once the weather cools off a bit (even slighty) we can get back to more aggressive practices.  We certainly do not want to compromise anything this time of year with our current weather patterns.

Our current mowing height is .115" mowed once daily and rolled 3x/week.

What is a Stimpmeter?

The 1976 device is an extruded aluminum bar, 36 inches (91 cm) long and 1.75 inches (4.4 cm) wide, with a 145° V-shaped groove extending along its entire length, supporting the ball at two points, 0.50 in (1.27 cm) apart. It is tapered at one end by removing metal from its underside to reduce the bounce of the ball as it rolls onto the green. It has a notch at a right angle to the length of the bar 30 inches (76 cm) from the lower tapered end where the ball is placed. The notch may be a hole completely through the bar or just a depression in it. The ball is pulled out of the notch by gravity when the device is slowly raised to an angle of about 20°, rolling onto the green at a repeatable velocity of 6.00 ft/s (1.83 m/s). The distance travelled by the ball in feet is the 'speed' of the putting green. Six distances, three in each of two opposite directions, should be averaged on a flat section of the putting green. The three balls in each direction must be within 8 inches (20 cm) of each other for USGA validation of the test.
