Not if the reference point is fixed and clearly identifiable (e.g. somebody holding a stick or something like that)?legend99 said:You're going to introduce a very high margin of error though if you're measuring an open space and you're trying to use a reference point every metres

Getting the angles right (90 deg at each corner) is always going to be a problem in any case surely? Or do these devices assist in that respect?legend99 said:Somebody holding a stick is definately going to introduce a margin of error. You would also have to manage to get the laser to hit the stick. Secondly, you are going to introduce error as you almost certainly would not manage to measure 4X15m in this way in a straight line. Each 15m measure is almost certainly not going to be 180 degrees (i.e. continuing in a dead stright line) from the last 15m so error will come from that.
