How do use the brick. Just set it behind the nail? No distance check . Just curious.
I always try to run through quick a check list of things I used that day......
Those days that I don't are the days that I forget something....:'(
Lol, same here. I still don't know where my good shovel and ax disappeared to, since I didn't notice they were missing till way after the last time I used them. I suspect non-returning "borrowers" might have had something to do with it.
I did leave a tripod and glass backsight on a construction site once. The Super picked it up and locked the stuff up in the job shack, but not before he gave the office a call. Yes, I was in trouble. :-$
Painted brick
I set control points with PK nails in open areas (and I emphasize open areas) using GPS, then later set up on them with my reflectorless. The backsight is a painted brick with a carefully marked vertical black line. I set the face exactly over the nail, and the brick perpendicular to the instrument. It is accurate, and cheap. If someone steals my backsight, well, there is a whole dollar gone. They are heavy and don't blow over or wobble no matter what the wind. The average discrepancy between the GPS distance and the reflectorless check distance is 0.01 feet. Rarely is it 0.02 feet, and anything over that I look for my error.
Yeah. I know what you mean. I leaned the shonestedt on the bumper, and drove over it. Dad took it and had it straightened at a muffler shop. It worked ok.... sort of. Eventually sent it in, and got it fixed though.

Twice I have had the local police (different jurisdictions each time) stop and steal a static GPS unit. Actually had a hard time getting them back. Yes they were away from the road on my clients property.
Was it one of those wood poles from the 1950s. I worked for Frank and Arlie in 1973 and they did a lot of hard work and were very good at what they did. except they would not make the move into the modern times or even look at or try newer equipment. I would that doubt they ever had a prism pole. In the office it was all longhand and DMD sheets and any ink on drawings was by crowfeet and open faced pens.
About 10yrs ago on a Saturday morning fishing trip to the lake I noticed a prism pole setup on a ROW monument where we had surveyed that week. I was wondering who was tying in a common point during the day. On the way back it was still there and I saw no one in sight and checked it out,
It was mine.

That hurts! (BTDT) Been there, Done That!
Painted brick
Very clever idea!
The absent minded Proctologist
The Proctlogist walks into the nurses station and one of the nurses asks him, "Dr. Butts, why do you have a rectal thermometer behind your ear?" The doctor takes it from behind his ear, looks at it thoughtfully and says "Well, I guess that explains where I left my pencil...".

Seriously, your really do have CRS disease!!
Wow..
Once I went to set up trimble TS and realized that I had left it set up next to the highway across town, I hightailed it back just in time to see a Ford F 1-50 making a U turn in two lane road.
Never been so happy to see a piece of equipment !!!
4X4 Chunk
It's not as solid a backsight as a brick, but I have a 4X4 chunk I've painted glo-pink and white with a vertical line down the middle. I set it similarly to the way you place the brick, Bruce, with a cone propped up over it. I balance a magnail, head down, on the edge of the 4X4 so I can tell from the gun if it's been disturbed by traffic. I haven't used this technique in a while, though, since I work solo with an S6 now.
:good: :good: :-$

Tooooo funeeee! That puts misplacing the prism pole on a hole new light;-)
I found my prism pole!
Obviously, right where I left it.....on an iron pin and metal t-post foresight on a job I went back to today. Imagine my shock and surprise to actually find it laying on the ground on the point I had shot in with my total station! It had spent the winter there, been underwater a few times, both bipod leg points had popped out, one thumb release rod had broken at the bottom threads, a lost cone piece, the inner rod lost its ability, to remain in the outer pole, the prism canister was full of water, and the prism backplate paint is starting to peel away.
With a few new parts, some steel wool, and a shot of WD-40, I will have it up and running again! This is like finding $350 in an old jacket pocket......!!! 😀
I found my prism pole!
Sounds like maybe the bipod legs filled with water and then froze, but the prism canister didn't fill with water before the freeze.
I found my prism pole!
Once, I had to shoot a 1/4 corner, WAY up on a mountain. There was a tree about 3' behind the corner. On this tree I make a huge target. And, placed a 4" x 2" piece of reflector tape. I was able to shoot it with my leica Reflectorless gun, but the distance was off by 1000 meters. It had exceeded the guns range, in reflectorless mode. I had to add in the 1000 meters, and shoot it in slope mode.
I never had to revisit that corner!

Maybe an idea from firefighters could help. On any fire that bigger than a dumpster fire, they set up a board, and everyone who enters the fire scene must take a tag off their turnout coat and clip it to the board. Just before getting on the apparatus to leave, each firefighter reclaims his/her tag. The safety officer looks at the board, and if any tags are left, everyone gets off the apparatus and searches for the missing firefighter.
How about one of these:
