3467 used one at GSD. We found it useful for seeing the robot behind the various high defenses, particularly the drawbridge and sally port. In most situations, it wasn't necessary, but it was quite helpful when we needed it. We made a fixture on the side of our driver console for the pole and it stayed in place for the entire match. The pole was made out of a telescoping tripod leg, which made it relatively easy to transport and adjust.
