Pretty neat Mike, just curious, has the crew ever bumped into it? I hope you get a chance to post some pics.
Diagram is not to scale...the mount sits only 2-3" from the gooseneck...so it's well forward on the boom...and the boom is quite low/close to the tramp at that end. Crew is never putting their head under that area. It's also very easy to reach the unit's buttons for start countdown and/or display changes.
