Hoodman Ground Control Point (GCP) Kits are made up of (5) 3Ft diameter, spring into shape, self-weighted circular pads that are numbered individually 1 – 5, or 6-10. The high visibility orange and black right-angle pattern of each GCP is easy to locate on video. The GCP Kit is made to last with galvanized steel perimeter cable and rugged polyester material. The weighted pad perimeter holds position with no need to pound in stakes. 4-tie down loops are included for long term GCP positioning where livestock might move the pads. Convenient 24 inch scaling constraint marks are printed into the pattern of each GCP. Each pad has a center grommet for surveyor staff placement for pinpoint accuracy of GPS coordinates. All 5 GCP pads weigh just 22 pounds total and fit snuggly in a convenient carry bag with shoulder strap. Cleanup is easy with mild soap and water. Be sure to let pads dry prior to placing in the carry bag to avoid mildew forming.
