...on a monopod
Hmmm... so your walking along, holding the camera by the monopod?
You must be grasping it right near the camera... you do this for landscape shots, where there is foliage ect... with such a 'brick'.. I dunna know...
Are you carrying it upside down??
I've used a monopods on other camera's, including my speed graphic, but once the shot, or shots, were taken, disconnected before discovering 'next' location.
