I chuckled at those, but then thought maybe I should try one. I've seen a bunch that go overboard (IMHO) with the pipe clamps and stuff. Just (electrical) tape the elements to the PVC and save some weight, cost, scratchy bits.
Would the tape measure tape work any different than say some 14# household wire? Is the tape just somewhat of a gimmick? Technically it's probably more metal, therefore better, but I wonder how it matters in practice. I imagine with wire you could just fold the elements up, rubber band them and be on your way. Watch yer eye though.
ETA: I actually read the article now and can see how the measuring tape would be much better for getting in and out of the car during fox hunts, which is what this is really meant for.
Edit the Second: If one used (electrical) tape (vs hose clamps), could they also skip the T and cross connectors and just use a length of pipe, or a broom handle or a stick? The (measuring) tape might want to just roll up, but it could be worth a try. Maybe wire would win in this application.
Edit number thrrrrreee: I realized I was talking about two kinds of tape, so I went back and clarified. C'mon bro.
