Golf gps are used mainly by golfers and by sportsmen alike. They are used to find bunkers, sand traps, and water traps on a golf course. If you are a competative golfer, they are useful.
Sand traps, or "bunkers" are placed on the golf course as hazards. Play from a hazard follows special rules, including the forbidding of touching your club to the ground before your actual stroke. The purpose of a bunker, like any hazard, is simply to increase the difficulty of the hole.
Sand dunes can help trap sand on a beach, they can also be called sand traps. It is a natural way of keeping sand on a beach.
because of the sand particles
The number of sand traps in a golf course can vary from course to course. For example, in my local course, it boasts only 35 sand traps averaging about 2 per hole. However, a golf course to my north has about 130 sand traps. Sand traps absolutely vary per course and can also reflect the other hazards that may be on the course. A course that has plenty of water may have fewer sand traps purely because there is already the penalty of water. Same can be said going visa-versa.
