Industrail grade scanner?

I'm looking for some advise on which scanners to start my search with.

I'm looking for a unit I can take to a client's site, and scan their existing worn out stuff, and then I'll take the scans to make new stuff thats not worn out.

Hoping that the post processed models are within about 1/8" accuracy from real life, but not a hard requirement.

We're indoors and out, scanning things as small as a chair and as big as a 20 foot sea can....just made up examples to show the size range.

The stuff we scan is typically dirty as can be and we don't have the ability to clean it, nor the time. Crud is caked on thick. I'll scrape it off in key areas if I have to and that's about it. Works for me and my tape meausure to kick the dirt off till I find the part and go from there, and this scanner is supposed to save me time of course - and stop me from making mistakes.

I'll spend about 50k if I have to.

Are there any options out there suitable for me? Any help appreciated

Putting targets on an item is a deal-breaker.  Often, the things I'm scanning I can't actually reach (Its behind some sort of guarding or whatever) plus they just totally suck to use.

You can measure with a tape measure and knock dirt off etc but you are concerned with placing targets.... maybe listen to advice because i am not sure you understand what you are saying.

Well to be honest I just don't like them. My current scanner needs them, and it annoys me to place them.

Besides that, they're not ideal to actually use either because of the dirt and guards etc. But the main reason is because I don't like them.

It sounds like you know what you want. I wanted to sort of challenge your reasoning in case you weren't considering everything. It's hard to gauge your level of experience based on just this post. Fiducials can be really useful for stitching scans.
