The course of fences a show hunter must jump is usually made up of 8-12 obstacles and must be set at the required height for each division. Obstacles must simulate those found in the hunting field such as natural post and rail, brush, stone wall, white board fence or gate, chicken coop, aiken, hedge, oxer, and so on. The fences in hunters are not brightly colored as in show jumping, instead they are natural rails or painted natural colors such as brown, green, white, and beige. Open water jumps and liverpools, common obstacles in show jumping arena, are not used in a show hunter course. Although combination fences may be seen, they are usually only two elements, and have easier distances between them than those found in show jumping. Banks and ditches are not found on the show hunter course, nor are any major changes in terrain, and often the horses jump on level footing in an enclosed arena.
