While there are much better models out there, Tool King has a “Grip” (a cheap import brand) 100′ long open tape measure on sale for $5.99. It will likely break at the first opportunity, but for that kind of cash if you get a few uses out of it you’d probably be ahead.
If you find yourself measuring long distances and hate running a 25′ or 50′ tape out and marking where it ends and running it out again, having a 100′ tape, even a cheap one, will save a lot of work. It’s perfect for setting up that archery range or laying out flagging for the road sprayer.
