Colleagues-
I had asked this before on "The Other Place" AKA "TOP", where, when, why, who uses plastic bars (about 16" long like this 
to mark legal boundaries ?
This is what happens when a six month old Golden Retriever gets to one and has the opportunity to nearly ingests the ceramic magnet
Thank you for your feedback.
Cheers
Derek
What's this???
I surveyor with a tape in inches.
What's up with that? 🙂

What's this???
What is the upside of plastic monuments? And I second E's question.
COOL!
you could use your schonstedt to find the dog!
What's this???
I was expecting a MM tape.
Plastic rod makes as much sense as a plastic tent stake. No sense at all.
Steve-
Purportedly one can drive them in (No one in Ontario seems to have heard of rocks and February) with abandon as there will not be any underground services hit!
Maybe, but cut into a plastic sheathing of a telephone line or gas line coating will certainly have a bad effect!
This is new Ontario Regulation link:
for 2. (1) A surveyor shall define each point in a survey that requires monumentation under this Regulation with a monument that is,
(a) a concrete pin;
(b) a cut cross;
(c) an iron bar;
(c.1) a plastic bar;
(d) a rock bar;
(e) a rock plug;
(f) a rock post;
(g) a short standard iron bar; or
(h) a standard iron bar. O. Reg. 525/91, s. 2 (1); O. Reg. 219/10, s. 2 (1).
(2) A surveyor using a concrete pin shall securely drive or wedge the pin into bedrock, concrete or asphalt so that the top of the pin is flush with the surface of the bedrock, concrete or asphalt, as the case may be. O. Reg. 219/10, s. 2 (2).
(3) A surveyor using a cut cross shall cut the mark into bedrock or concrete so that it is five millimetres across and five millimetres deep. O. Reg. 525/91, s. 2 (3).
(4) A surveyor using an iron bar sixty centimetres long shall plant the bar in the ground so that the top of the bar is not more than ten centimetres above the surface of the ground. O. Reg. 525/91, s. 2 (4).
(5) A surveyor using an iron bar less than sixty centimetres long shall wedge, cement or lead the bar into bedrock, concrete or asphalt so that the top of the bar is not more than five centimetres above the surface of the bedrock, concrete or asphalt, as the case may be. O. Reg. 525/91, s. 2 (5); O. Reg. 219/10, s. 2 (3).
(6) A surveyor using a rock bar shall wedge, cement or lead the bar into bedrock, concrete or asphalt so that the top of the bar is not more than five centimetres above the surface of the bedrock, concrete or asphalt, as the case may be. O. Reg. 219/10, s. 2 (4).
(7) A surveyor using a rock plug shall wedge, cement or lead the plug into bedrock, concrete or asphalt so that the top of the plug is not more than 25 millimetres above the surface of the bedrock, concrete or asphalt, as the case may be. O. Reg. 219/10, s. 2 (4).
(8) A surveyor using a rock post shall wedge, cement or lead the post into bedrock, concrete or asphalt so that the identification cap is flush with the surface of the bedrock, concrete or asphalt, as the case may be. O. Reg. 525/91, s. 2 (8); O. Reg. 219/10, s. 2 (5).
(9) A surveyor using a short standard iron bar or a standard iron bar shall plant the bar in the ground so that the top of the bar is not more than ten centimetres above the surface of the ground. O. Reg. 525/91, s. 2 (9).
"plastic bar" means a bar that is made out of high impact plastic, that is 25 millimetres square and at least 30 centimetres long and that has an embedded magnet;

I found these in use by a design company on a road project once. The proposed new road was to run very close to a cut-out I was doing for a new water tower. I wanted to make sure that the line for the water tower stayed out of the proposed new road, so I got the plans and found the alignment had been staked with these plastic stakes.
They were in the ground pretty solid and easily visible due to the plastic color and size of the top. That seemed to be a good use for them.
What's this???
We use plastic tent stakes as hubs. They look just like that.
But not for monuments, that doesn't meet our MTS.
:coffee:
What's this???
We have a lot of latitude in Texas with regard to monumentation. We COULD use these if we wanted. There are a few places where we've set non-standard monumentation just so it will survive. The one that jumps into my mind was a 2" copper pipe, 5 feet long, set in a bog on Mud Creek bank with a 1/2" steel rod inside and 5 witness trees to the pipe. The rod wouldn't have survived. PVC pipes on creek banks with a rod or magnet in them, driven to refusal, would make a decent corner. Although, so would a big ol pine knot as well.
Every other place would probably get a steel rod.
