I worked with an old Navajo laying out MX missile silos. Plans called for them to be tilted west in such a way that the missile headed for Russia. The Indian reversed this to east and we never stopped accusing him of trying to take out the great white fathers in Washington DC....and he didn't deny it.
I pay more attention to the rod bubble then the tip, but I guess it all adds up. I have a leica 2 piece aluminum rod with a carbide tip. In 4 years it still looks good. The tip is just a small bump on a blunt tip.
But then again I'm one of the GPS people who don't need a tip.

I've never seen a carbide tip on a pole, but I'd like to find one. Do you have a part number for that?
All that she wanted was the tip........
Sorry, I couldn't resist
Replacing the tip when they get blunt is a prudent thing to do. These things cost about $10, for crying out loud. Old ones can serve on the bipod legs.
I use a topo shoe when doing topo. Keeps the sharp tip going longer.
In Industrial settings we work in sub millimeter tolerances setting and aligning equipment. We come across others claiming millimeter accuracy using worn tips on 5 foot prism poles, construction grade total stations, scribe marks in concrete, etc.
Back when I first started working on a survey crew, one of the other guys hurt his foot by sticking a new prism pole point into the top of that. After that, he started beating the tip with a hammer to dull it.

No, sorry I don't. I picked it up from a sales man that was doing a demo for a friend. I saw the same pole a while back searching Leica's web site.

Jim,
If you can afford it, shell out on a Leica gls11 or gls12 prism pole. They come with the carbide insert. The larger metal part of the tip will wear down before the carbide insert, and eventually the carbide insert will fall out because there isn't enough of the rest of the tip surviving to hold it in place. The whole tip assembly is replaceable on both.
We take many EDM shots from 6000 feet on down. A half mile is common and a quarter mile is very frequent. Trust me, the width of the tip on the prism pole is going to be about the smallest potential error involved.

Conrad,
Where did you here the tips are replaceable? I have quite a selection of GLS12s with worn down tips and the local dealer says the points are not replaceable. I would love to find out they are.
The other day I was wishing for pole points with plumb bob point tips - http://www.benchmarksupply.com/crain-aluminum-prism-pole-point-91605.html&apos ;">Found 'em!

Hey John,
I got one here ready to go in when I get the time.
They are glued in. The extendable part of the pole has some rubber at the bottom so you'll need to extend the pole before you apply a flame to the tip to break the bond holding the tip assembly in.
And for GLS11, part number is LG703855.

Those and the screw on boot came on the Crain solid section poles and my PM3s.
The boot will screw into the bottom of the Crain level bubble.
After 7yrs they are still in great shape.

The tip itself looks like it might be threaded into the conical part above it, similar to the the way the newer hardened steel points attach. I'm wondering if it might be a direct replacement for the steel version. Have you ever tried to disassemble the item pictured?
P.S. A Google search failed to turn up any Leica references to those part numbers. I guess I'll have to contact a Leica dealer and inquire as to availability and cost.

I think you'll have a hard time finding spare parts numbers. More likely only to find part numbers for the expensive gear and accessories.
Just for you:
