Do any of you think that it would be possible to meet a 1:10,000 closure requirement with an old fashion gurley-type transit and a cloth tape? Oh, you're a one man crew with a screwdriver to dead-man the tape. Bonus question: would video of someone surveying in such a manner be prima fascia evidence of one not meeting current standards?
Btw the plats always seem to match record to the arc second and .01'.

Give Me A Survey Size And I'll Give You An Answer
Otherwise it depends.
My father did a lot of one man surveying, probably more accurate that when he dragged his sons out into the field to help.
He would tape 3 times, carried an eye level and did slope adjustments in the field.
No, not with a cloth tape.

The Gurley transit - yes. Cloth tape - well ....? And only anchoring with a screwdriver - that I really doubt because I can't imagine pulling any tension at all without pulling it out of the ground.
The answer would be in retracing his footsteps where he created a new parel with no call information.
He probably couldn't meet 1:10,000 unless he twists a lot of D&R sets, tapes multiple times, and knows what correction to apply to taping.
On the other hand, as someone's signature line says, you don't have to be a very good surveyor if you find all the corners. For lot retracements and proportioning in missing corners he probably isn't doing much harm if he follows the right legal principles. Is the standard really 1:10,000 for that in your jurisdiction? Some people cause a lot more confusion and discord with near-perfect measurements.
Is the really a question about what equipment is being used or is the guy just doing sloppy work? A guy with a transit and a cloth tape could probably do acceptable work if he was finding the corners and doing the research. My question would be why? I would think a guy could put together a used total station, tribrachs, prisims and a pole for no more than 10k if you bought used a shopped carefully. You might even be able to do it for less than 5k.
The real advantage ....
of transit and (steel) tape is NO BATTERIES REQUIRED. And some crackers, can of Vienna Sausages & a Dr. Pepper will get you through lunch.
No, No No, Dave....
Crackers, venison hot sticks and grapefruit juice.
Don't tell Ted, but I sometimes substitute water.

It is probable that a surveyor can get a 1:10,000 closure with a cloth tape and transit.
I doubt that the information will match that of work done with a steel chain using proper procedures.
Just because everyone's results reflect a 1:10,000 closure does not assure that the distances between points will be the same for everyone.
I've followed a few surveyors that always mirrored other known surveys exactly.
Their original work was something that fell in the WTF category.

The venison sticks would be acceptable. But no self respecting man South of the Mason Dixon line would pass up a Dr. Pepper! And where in the world did grapefruit juice come from?

Don't know where it came from, but I know where it belongs

Grapefruit juice works to rehydrate me. The high electrolite content of Gatorade sickens me. At the end of the day if I am still beat I go for a cold grapefruit soda. An end of the day alternate is celery soda.
I grew up on Moxie, Dr. Pepper never appealed.
Of course now as the weather cools sipping fluids can have more moxie than chugging fluids. I can abide with anything they sip in the South.

For a get-by meal, you can't beat crackers and sardines, but the cats may FOLLOW YOUR FOOTSTEPS,all day long.

Possible but really unlikely. And easy to prove. State Boards love stuff that can be proven with mathematical certainty. So much easier to enforce than boundary resolution judgement calls.
John, OK As Long As The Rodman Does Not Want A Hot Lunch
Warming on the engine block is OK, but if he forgets, after it explodes you smell it for months. No other crew will trade vehicles with you either.

How long is the screwdriver? Is it on a -1' offset (subtract chain?)? 😉
Precision vs accuracy!!
If his procedures are consistent and you use only his numbers precision (repeatability of measurement) may approach the standard. However any checks against more accurate equipment, 10" theodolite and steel tape or EDM, would be very difficult to meet that for accuracy.
old school v new standards Bill

It is very true isn't it? 🙂
Dr. Pepper?
> The venison sticks would be acceptable. But no self respecting man South of the Mason Dixon line would pass up a Dr. Pepper! And where in the world did grapefruit juice come from?
I beg to differ on that Dr. Pepper statement. I've never been a fan of Dr. Pepper or any form thereof. Being a type 1 diabetic, I've turned down Dr. Pepper as a substance to raise my blood sugar from causing me to black out. I truly hate the taste of it. Although, since getting older my taste buds have degraded, I might be able to tolerate a sip or two to keep myself from dying. :-/
Just wanted to chime in as a self respecting man South of the Mason-Dixon.
Precision vs accuracy!!
From observing this fellow on several occasions, his method seems to be some sort of baseline-offset thing.
When I questioned him about his technique once, he said it was close enough and asked me if I wrote a new legal description for every lot I surveyed. That was his defense for perfectly matching record calls.
Thanks for the nasty lunch hijack...yuck.
