A slope indicator for indicating the slope of a golf green, comprises a polycarbonate flat circular base and a dome-shaped transparent cover that is filled with distilled water and has an observable bubble. The base has a spike extending from its lower surface and a circular flange extending from its upper surface that has a circular slot. The cover has a periphery which has a circular slot that receives the base flange to form a dome-shaped chamber having a predetermined volume. A direction indicator and radially-spaced slope markings are molded into the cover. The slope indicator is assembled by inverting the cover and metering a predetermined quantity of distilled water into it that is less than the volume to create the bubble. The base is then assembled to it with glue. In use, the slope indicator is placed on a golf green with the spike engaging the golf green. If there is any slope, the bubble will displace from the top of the dome. The slope indicator is rotated to align the direction indicia with the bubble to indicate the direction of slope of the golf green. The degree of slope of the golf green is indicated by the displacement of the bubble from the top center of the cover as measured by the position of the bubble relative to the slope indicator.
A slope indicator for indicating the slope of a golf green, comprising a circular base having an upper surface and a lower surface, a spike extending from the lower surface, a circular flange extending from the upper surface, a dome-shaped transparent cover having a peripheral flange which is received by the peripheral circular flange to form a dome-shaped chamber having a predetermined volume, and a predetermined quantity of liquid confined within the chamber, said quantity being sufficiently less than said volume to create a bubble of sufficient size to be observable by a golfer when the slope indicator is placed on a golf green with the spike engaging the golf green, whereby the degree of slope of the golf green is indicated by the displacement of the bubble from the top center of the cover.
A slope indicator for indicating the slope of a golf green, comprising a circular plastic base having an upper surface and a lower surface, a spike extending from the lower surface, a circular flange extending from the upper surface, a dome-shaped transparent plastic cover having a peripheral flange which has a circular groove that receives the base flange to form a dome-shaped chamber having a predetermined volume, a predetermined quantity of water confined within the chamber, said quantity being sufficiently smaller than said volume to create a bubble of sufficient size to be observable by a golfer when the slope indicator is placed on a golf green with the spike engaging the golf green, direction indicia, and radially-space slope indicia carried by the cover, wherein the base lower surface is flat to enable the slope indicator to be rotated when placed on the golf green to align the direction indicia with the bubble to indicate the direction of slope of the golf green whereby the degree of slope of the golf green is indicated by the location of the bubble relative to the slope indicia.
