The carbon fiber pole will practically weld itself to your hand above 100å¡F. I have seen sleeves over them being used as a hotpad to hold onto.
Similar to Nate, I use high stakes, 6d nails and these targets I make out of reflective tape and 3/8" hose. They slip on the heads of the nails. I set the traverse up first and then run it. Closures are great. I use the tape on the corners and prismless on the blaze trees, buildings, etc.
I use my robot for the roads, topo and heavy detail. Many different tricks.
Safety is a problem. When I'm going out to a long hike in the mountains I usually tell the wife, if I don't come home tonight, this is where to search for the body. She don't think it is funny but someday it will probably be the truth. Where else to die than working on some Ridge Line somewhere.
One thing I did do was lose thirty pounds early this year. The hills are not quite as steep. Next I need to get some newer much lighter gear. Then lose some more weight. After that the grandsons are about to kick in, first as pack animals and then operators but I suppose I won't be solo after that.
Like they say, getting old isn't for sissy's!
I do a lot of solo surveying.
For some survey locations well beyond the end of a road, I take somebody with me because something may happen.
Some of it is the miles and some of it is the years and some of it was due to the condition of the road.
Not a frequent problem in Alaska!
On the flip side they can be a bit brittle at -30F.
Just because I'm paranoid, doesn't mean they aren't out to get me.
Iphone has a "Find Friends" app that works great. At any given moment my wife can see exactly where I am, overlayed with a road map and aerial. (Note: Not advised for the cheating husband)

^^^Lol!
Conventional Leveling solo is a real drag, but if you get a trig leveling setup it can be a great equalizer. You can double your site distances (500'-600', sometimes more) over conventional leveling. That means you can often get over 1000' per turn without worrying about the steepness of the terrain.
Get 2 identical items of each: 4' Range Pole, Topo Boot, Male to Male 5/8" Adapter, Prism Target with Large Sights, Bipod, and leveling bubble. Put that all together tightly and you should have 2 prism poles of identical height (make sure you check this). Then use your total station as your level recording the VD and HD data (Averaging the Direct and Reverse readings however many sets you take, also make sure you calibrate your collimation and bubble axis before your run). The Delta Elevation between stations is the FS VD minus the BS VD. Adjust the data with a spreadsheet or Adjustment program and away you go. The amount of sets you take depends on the precision of your instrument and sight distance. The HR is irrelevant because your rods are identical and the HI is irrelevant because you are only measuring the difference in elevation between the 2 rods. I have a 5 second gun and I take 2 sets and don't have a problem getting 3rd order precision. I have heard with a 1-2 second gun you can achieve second order precision, but I have never tried it.
So that's not a solo setup then?? You still have a person turning angles?
Why are there so many messages "removed from public view"/??? If they are going to be deleted, why leave a note about it??

Suppose you need to locate a point that is, say, 5' from your line of sight, but requires a little more accuracy than you can get from a regular offset shot. Stick two nails in the ground on your line of sight, forming approximately a 90-degree angle with the point you need to locate. Shoot the two nails and measure from each one to the subject point. Then do a distance-distance intersection from the nails to calculate the point you need. I've saved a lot of setups this way.
This works well, and I've used it often. Also, when I'm able to estimate in advance where a corner is going to fall, I set 2 or 3 random nails around that point and shoot them along with the evidence. Saves a setup when returning to place the monument.

I have run carbon fiber poles for a decade, and have never encountered this. If anything, aluminum poles would be more worrisome then carbon.
I have a friend who swears by this, and my conventional crew has been testing with some very good results. My friend works on very tight const. sites where his control is constantly being destroyed or disturbed. He sets mag nails in power poles, or smooth faced trees and shoots the dimples reflectorless. Upon returning to the site for more layout work, he can then find any 3, and do a 3 point resection. We have done it so far with our reflectorless instrument (Topcon) and the worst we've been out for distance is 0.02 and the worst for angle has also been 0.02. I'd say the average has been less than a hundredth on all of them. So far, I'm impressed.
Looks like this can be done on an Android with maps so I'm going to try it. I'll need to get a backup battery pack as when GPS location is on it drains the battery in no time. The downside is I really don't care to have the rest of the world knowing where I am. There are places I work with no cell coverage. Google offers a lot of stuff free to users but then they sell all your info to everybody that wants it, sort of a deal with the devil.
