Nebraska maybe...
I surveyed Nebraska for 15 years; we'd use a 300 footer all day long. Never seen a 500 footer...
Don't forget to correct for temperature; Hot or Cold!

I used an 8 chain tape (528 ft.) a couple times, never got the "hang " (float) of it. Not very useful in the timber of the Uinta Mountains.
I have seen Field Notes of US Mineral Surveys where a 600 ft. tape was used, but I don't know how the hell they did it considering the terrain (and timber/brush) involved.

I have used a 300' one.?ÿ
Javad is better.

no, 300' all the time, never 500'
300' on a lot of surveys. Used 5 chain tape when I worked for Worthington & Lenhart in 1959-1960 when doing well locations. The 5 chain tapes were a ribbon tape held waist high and eyeballed over the point (tail chain) and dropped a hatchet (head chain), measured on the slope and corrected to horizontal with a clino angle and the Traverse tables in the Red Book.
Used the same procedure with the 300' tape, but used a plumb bob on each end, vertical angle with clino, corrected?ÿ to horizontal using Red Book Traverse tables and adding the corrected distance to the stick point for the full 300' tape measure. Chained many many miles this way.
I have a 500' tape I?ÿgot from an old mineral surveyor from Cheyenne, Wyoming in 1973 when I purchased his Ainsworth solar transit. Also included with the purchase was an old level rod, stainless steel chaining pins, and his old equipment travel satchel.?ÿ
We used 600 foot chains.?ÿ

They wouldn't last for ever, due to constant winding on a small reel plus being very thin and fine. ?ÿThey'd get to the stage where suddenly they'd roll into spirals on their own accord.
600 feet is a heck of a long way from end to end and it was a task to ensure you weren't snagged. They were great across quarries and gullies.
Had to be careful around power lines though. Easy to flick and up they'd jump!
They did have a valid place though in our survey gear arsenal. Then came EDM. Ah! The Bliss!?ÿ
I've seen a 500' chain but never used one.
It would be interesting to try and throw one of those. You'd have to have a pretty big rear chainman.

Been there, done that (528'er)!
You had to be careful, those babies could take you whole face off if you screwed up. ??ÿ
Okay, not really, but they WERE a PITA to "do up & throw." Un-throwing them was probably the worst part (and most likely to result in pain).

in the early 70's in the NorthWest we had one, in the equipment room. It went out with one of the crews occasionally. It was ultra narrow, not babbitt like the eBay link, Chromeclad type, ultra narrow, and on a modern Lufkin Chromeclad brand/style reel, but it did not lay flat and was a clumsy looking thing. I never used it.
Like a First Aid Kit, hardly (if ever) actually used by anyone.
We used 300' Chromeclad 99% of the time (until HP3800), but it was still the primary tool.

We done the 5 Chainers up in a figure 8. Either one of the chainmen would hold the head end and the other person would make the loops, about a 5 or 6' stretch depending on a persons reach. Or, if necessary, the head end could be attached to a fence post and one person could make the loops. Once all done up, then the loops could be folded together and tied with the thongs. A 300 footer could be done up the same way if there wasn't a reel for it.
Nope.?ÿ Mostly used 100' steel tapes. But when working for BLM we used a 300' Invar tape quite regularly if the terrain permitted it or it was required for triangulation baselines.?ÿ It was prone to breakage due to twists; it wasn't snappy like a steel 100' tape.?ÿ The wooden reel for with was long gone so it had to be thrown by experts on the crew and put in a canvas sack.?ÿ
Chaining has become a lost art.?ÿ A good crew using a 100' cut or add steel tape with chaining pins, abneys and using due care could achieve 1/1000 on a good day, even in difficult terrain.?ÿ?ÿ
There's an outlaw in my area that still uses a 500' surveyor's rope! Not uncommon for him to be?ÿ 10,20,30....50....100 feet off. I think he makes most of it up.
We had a 300' "CUT" chain (read the feet and subtract the hundredths) or as we called it "Buster" 'cause sure as shooting if you used that chain you were going to bust at least 1 distance.
?ÿ
Yep, common in the tunneling industry.?ÿ
Never have used one.
I've never even seen such a thing.?ÿ I think I would need a truck to haul it around because it must weigh 30 pounds?
I only used a 200' steel tape (we called it a "chain", even though it was really a steel tape). Ours was an 'add" tape, 1' marks throughout and then an extra foot with 1/100 graduations.When doing it up, I learned to extend my arms and put my hands on 5 foot marks so that it would be wound up evenly. Still can do that very handily with a 100' extension cord, never any left over after 20 loops.?ÿ?ÿ

The other day we were using a 100' steel tape to measure between two points, first time in years, did it as a check. When the end of the tape got to me, I instinctively yelled "Chain", the guy at the other end didn't know what that meant. Not sure if every crew did that, but I was taught to yell "chain" when the end got to me.?ÿ

I remember climbing a tree years ago (at the request of my curmudgeonly party chief) to get a visual on a back-sight in the course of laying out a traverse.?ÿ I had made it to the top of what I considered "as far up as I could go"...but the PC thought I should get a "little higher".?ÿ I tried.
The party chief had made it a few feet up the trunk and was supervising my ascent from below.?ÿ Suddenly a limb snapped beneath my foot and I fell straight down toward my boss.?ÿ He instinctively began hollering "Chain! chain, dammit!"....It didn't do a bit of good.?ÿ I fell on him and we both made it to the ground in a nanosecond?ÿwith all sorts of scrapes and bloody scratches.
As we dusted off ourselves the old fart reiterated, "Didn't you hear me hollering?"
I explained I heard him well, but found my fingernails did little to stop my fall when trying to grab the slick bark of an ash tree...
