I noticed this in the description of it, took a while to sink in.
"We have designed an anti-rotational channel that runs the whole length of the shaft to stop the shaft and control box twisting sideways, this also adds extra strength to the whole shaft."
While I do believe it's a good thing for the detector while you're swinging or telescoping, when it comes to storage/transport if you can't rotate it 90 degrees somewhere along the shaft, you're stuck with a "T" profile, rather than a a flat "l" profile.
I guess my goal is actually to get the shortest, most compact package possible to better fit on my motorcycle. Sometimes you just can't have it all.
