In April 2024, one of our engineers found a used FARO Vantage laser tracker listed at 40% below list. It had a hard case, a calibration sticker, and a seller who answered every email within an hour. We almost bought it. Actually, I almost approved it, and that is the part that still keeps me awake.
I went back and forth between that used unit and a new system for two weeks. The used unit offered $35,000 in savings. The new system offered a warranty, a clean service path, and a delivery date written into the contract. The spreadsheet said the used unit made sense. My gut said something was missing. Turns out the “current calibration” wasn't current at all—it had been issued before the instrument was shipped cross-country to the seller, and the shipping damage wasn't documented anywhere.
We didn't buy it. A month later, the same model appeared in an online auction with no calibration certificate and a scratched reflector. It sold for less than half the original asking price. Whoever bought it didn't get a bargain. They got a project risk.
This isn't a story about one bad listing. Over the past seven years, I've managed our equipment budget—about $300,000 a year for a 40-person metrology services company—and I've logged every order in our cost tracking system. I've also negotiated with more than 30 vendors for calibration, repair, and equipment purchases. The pattern is clear: used test equipment can save you money, but only if you evaluate it the right way.
The Surface Problem: Sticker Price Camouflage
When a FARO Vantage laser tracker is listed at $55,000 instead of $90,000, the first number is hard to ignore. Those are illustrative numbers as of January 2025, by the way. Verify current list prices from FARO or an authorized dealer before making any decision.
A 40% saving feels like a smart procurement move. Sometimes it is. But the purchase price is only the first installment of the real cost. The rest is hidden in calibration, support, downtime, and the quiet cost of losing a customer's trust.
The same logic applies beyond laser trackers. I once watched a colleague evaluate a used ophthalmic microscope for a clinic. It was 30% cheaper than a new one from an authorized dealer. It had all the same dials and lenses. What it didn't have was a clear answer to one question: is Microscope World an authorized Zeiss dealer? That question, asked before the purchase, changed the whole decision. Without authorization from the manufacturer, firmware updates and spare optics become a gamble.
I've also seen the opposite mistake: dismissing all used test equipment as junk. That is just as wrong. A used oscilloscope from a lab that is closing down can be a legitimate buy. A used FARO Vantage laser tracker with a current calibration certificate and a real service history can be a smart investment. The problem is that the good opportunities are mixed in with expensive traps.
The Deep Problem: You Are Buying a Promise, Not Hardware
Here is what I learned the hard way. A precision measurement instrument is not a collection of motors, mirrors, and aluminum. It is a promise. The promise is that when the instrument says a dimension is 12.345 mm, the dimension is actually 12.345 mm—within a known tolerance.
That promise is documented in a calibration certificate. The certificate is the product. The hardware is just the container.
According to FARO's published product information (faro.com, accessed January 2025), the Vantage laser tracker is designed for portable, large-scale measurement. For anyone who wants the formal version, ASME B89.4.19 is the standard used to evaluate laser tracker performance. It assumes a properly calibrated instrument. If the calibration is suspect, the standard's numbers do not tell you anything about the actual tracker.
Calibration Is Not the Accessory. It Is the Product.
When you buy a used unit from an individual, you often get a copy of an old certificate. Maybe it's from last year. Maybe it's from three years ago. The question is: who issued it, and what did they actually test? A PDF of a certificate is not the same as a current calibration record.
I built a cost calculator after getting burned twice on hidden fees. The first time, a “great deal” on a used test instrument needed a $2,000 recalibration and $1,400 in missing cables. The second time, a “free setup” turned out to cost $450 more in hidden fees. In both cases, the initial price looked like a win. The final invoice told a different story.
Service History Is Easier to Fake Than You Think
I used to trust service histories. Then I audited our own records and discovered that a “fully serviced” laser tracker had been repaired twice for the same alignment issue. The repair notes didn't include the verification data. The seller said “just calibrated.” The documentation suggested otherwise.
The used unit came with a service log. Or rather, it came with a folder labeled “service log” that contained three printouts and a sticky note. That was the moment I stopped believing the phrase and started asking for evidence.
The most frustrating part is the language gap between sales and quality. A seller says “good condition.” What they mean is “it turns on and looks okay from the outside.” Our quality team needs proof of within-spec performance. Those two worlds are very far apart.
Support Is Not an Optional Extra
New equipment comes with a support structure: software updates, firmware, phone assistance, a service network, and someone who actually picks up the phone when a machine goes down. Used equipment from an unauthorized source comes with exactly what you can see in the photos.
If the seller doesn't have a current service agreement with the manufacturer, you're not buying used hardware. You're buying a support gap. In our industry, support gaps show up at the worst possible moment—right in the middle of a deadline.
The Real Cost: It Is Always a Deadline
Let me give you a concrete example. In March 2024, we paid $400 extra for rush delivery of a calibration artifact. The alternative was missing a $15,000 client event. The extra $400 bought certainty. The cheaper option—waiting for the regular shipping schedule—would have saved money on paper. It would have cost us a relationship.
In an emergency, the value of a tool is not its price. It is whether it works when you need it.
We see the sharpest version of this every fall. Our team staffs seasonal FARO laser tracker jobs for a large customer, and the deadline is fixed by their production schedule. If a laser tracker goes down mid-job, we can't tell the client to wait. We don't have a backup. In those situations, I would rather pay 20% more for a system from an authorized source with guaranteed delivery than save 20% on an uncertain one. The premium is not for speed. It is for certainty.
After seven years of tracking every equipment invoice, I found that about 30% of our budget overruns came from just two root causes: overtime caused by equipment failure and rework caused by questionable measurements. Not from bad estimates. Not from scope creep. Equipment.
The surprise wasn't the price difference between new and used. It was how much hidden value came with the “expensive” option—support, calibration, and a delivery date I could actually rely on.
What Changed: A Short TCO Checklist
Here is the short version of what our procurement policy looks like now. It's not dramatic, but it has stopped us from making expensive mistakes.
- Ask for a current calibration certificate before the price conversation. If the seller can't produce one, the rest of the conversation doesn't matter.
- Verify OEM authorization. If you're buying a used FARO system, ask if the seller is an authorized FARO reseller or service partner. If you're buying an ophthalmic microscope, ask the same question about its manufacturer—for example, “is Microscope World an authorized Zeiss dealer?” Do not guess.
- Calculate total cost of ownership, not purchase price. Include recalibration, shipping, insurance, software updates, support, and the cost of one day of downtime.
- Get a delivery date in writing. When a deadline depends on it, a guaranteed date is more valuable than a 10% discount.
I'm not saying never buy used test equipment. I'm saying don't buy it on price alone. The real question is what you're buying along with it: certainty or risk. I do not trust “as-is” listings for precision instruments. Actually, that is not quite right—I trust them completely. “As-is” means exactly what it says: you are accepting everything unknown about the unit.
The spreadsheet said buy the used tracker. My gut said the risk wasn't worth it. After watching that same risk show up in deal after deal, our policy now says the same thing: when the measurement matters, and there's a deadline attached, certainty is worth the premium.
