As the trail gets more difficult, the spotter becomes more importantJenn Pozniak
When the driver can plainly see the route with only an occasional rock or obstacle impeding progress, no spotter is needed. As the route gets more difficult, a good spotter becomes a valuable player in the mix.
A good spotter is usually also a good driver. Why? Unless you experience the capabilities and eccentricities of a rig, first hand, by driving it, it's very difficult to know what to expect of those characteristics on the rocks.

The spotter needs to know what the spotted vehicle can and cannot do. This means knowing at a quick glance WHAT will clear, and WHERE under the rig. A good spotter knows where to position the tires and differentials for that clearance. Sometimes the route requires the tires to be on top of the rocks, sometimes between, sometimes directly over. Spotters know in advance how much traction the tires have in a given situation, including the inflation (including any loss of center of gravity due to lower inflation), steepness of the obstacles, and the grip on the surface. Knowing what kind of style the driver prefers is also important. Drivers eager to use the 'Moab bump' may prefer to hit the same obstacle faster than those who like to 'tractor' over obstacles.
