This monopod differs from most others because of its' single-hand operation. The Bogen 3245 monopod allows the height to be adjusted with a one handed trigger mechanism built into the handle. The monopod consists of three sections, with the first two sections conventionally configured. The third section's height is controlled with the trigger. Now changing the monopod's height is a snap; there simply is nothing to prevent you from adjusting the height perfectly. No more straining your neck to accommodate a slightly too high or too low viewfinder."
