What to Look for When Buying Used Survey Equipment: A 7-Step Checklist (Plus a Bonus)

Buying used survey equipment can save you a ton of money — if you know what you’re doing. 

The trick is to make sure you’re not just scoring a deal but also avoiding a dud. That robotic total station or GPS receiver might look great in the listing, but what’s under the hood? It’s all about asking the right questions, spotting red flags, and knowing how to separate the good deals from the bad. 

Whether you’re outfitting your crew or replacing a single piece of gear, this 7-step checklist (and the bonus step) will help you buy like a pro and avoid costly mistakes. Have questions after reading? We’re always here to help. Contact us any time.

1. Assess the Seller’s Reputation

The seller’s reputation is everything. A great seller moves product, but they also stand behind it. Think of it this way: The right seller will have already done the heavy lifting — sourcing high-quality gear, testing it thoroughly, and making sure it’s ready for action.

So how do you spot one of the good ones?

Start with their ratings and reviews. A seller with glowing feedback and repeat customers is someone you can trust. Bonus points if their reviews mention things like “great service” or “knowledgeable about equipment.”

Next, look for expertise. The best sellers aren’t just flipping gear — they know the ins and outs of survey equipment. They’ll answer your questions without hesitation and might even teach you something along the way.

And don’t forget after-sales support. Does the seller offer a return policy? If not, move on. A solid seller stands by their equipment and will work with you if something doesn’t go as planned.

2. Evaluate the Equipment’s Condition

Evaluating the condition of used survey equipment is a non-negotiable step. Start with a physical inspection — what you see on the outside can tell you a lot about what’s going on inside.

First up: cleanliness. Equipment that’s been cleaned and maintained is usually a sign of an owner who cared. If the listing shows equipment that’s covered in grime or shows other signs of obvious neglect, that’s a red flag.

Next, look for wear and tear. Scratches and scuffs are normal, but cracks, missing parts, or anything that screams “hard life on a job site” should give you pause. Check out this clear comparison between equipment that's worked hard and equipment that's been well-loved.

Once the physical check is done, it’s time to test it out. If you’re looking at a listing on eBay or another marketplace, ask the owner these questions. Does it power on? Do all the buttons, screens, and connections work as they should? And don’t forget calibration — survey equipment isn’t worth much if it can’t measure accurately. If it’s out of calibration, ask if it can be recalibrated, and factor that cost into your decision.

Remember: a little diligence now saves a lot of headaches later.

3. Verify the Equipment’s Legitimacy

Here’s the hard truth: not all used survey equipment is legit. Some might be stolen, others may lack the right software or licensing to function properly. This is where serial numbers become your best friend.

Start with an authenticity check. Ask the seller for the serial number and use it to confirm that the equipment is genuine and matches the description. Many brands, like Trimble or Leica, have ways to verify equipment through their databases.

Next, confirm the software situation. Survey equipment often requires specialized software or licenses to operate. Make sure it’s included, properly licensed, and compatible with your existing equipment and systems. Replacing or renewing licenses can be an expensive surprise.

And let’s talk about theft. Unfortunately, stolen survey equipment is a real issue, especially for high-value items like total stations. Use the serial number to check with the manufacturer or online registries to ensure it hasn’t been reported stolen.

Finally, watch for red flags. If a seller hesitates to provide the serial number or gives vague answers about the equipment’s history, walk away. Transparency is key, and a good seller will have nothing to hide.

4. Check the Equipment’s Usage History

Survey equipment works hard on job sites, and its usage history can tell you a lot about what you’re getting into. Think of it like buying a used car — you wouldn’t skip asking about the mileage, right? The same goes for total stations, GPS receivers, and other gear.

Start with total operating hours. Many types of equipment, like robotic total stations, have built-in logs showing how many hours they’ve been used. Higher hours aren’t always a dealbreaker, but they might mean you’ll need maintenance sooner rather than later.

Ask for maintenance records, too. Did the seller regularly service the equipment? Have any repairs been made? Documentation of past upkeep can be a reassuring sign that the gear was well cared for.

Most importantly, a trustworthy seller will disclose this information upfront. If they hedge or seem evasive, that’s a problem. Good sellers know that informed buyers are happy buyers, and they’ll have no issue sharing the usage history of their equipment.

5. Ensure Compatibility and Specifications

Buying used survey equipment isn’t just about getting a good deal — it’s about getting gear that actually works with what you already have. Compatibility is king, and overlooking it can turn a “bargain” into an expensive headache.

Start with system compatibility. If you’re working with modular components, like many of Trimble’s systems, double-check that the parts you’re buying will play nicely with your existing setup. A receiver that can’t sync with your controller is just an overpriced paperweight.

Then, dive into the technical specs. Does the equipment support the radio channels and satellite systems you need for your region? Some older models may not be compatible with the latest GNSS signals or might lack the flexibility of newer technology.

Finally, confirm software compatibility. Will the equipment’s software integrate with your current systems? If you’re upgrading piecemeal, mixing older and newer components can sometimes create unexpected problems, negating the benefits of your investment.

When in doubt, ask the seller — and don’t be afraid to dig deep. Compatibility is critical, and a little extra legwork upfront ensures you won’t be scrambling to fix problems later.

6. Watch for Red Flags

Even if a deal looks great on paper, certain red flags should make you hit the brakes. Spotting these warning signs early can save you from wasting money — or worse, getting scammed.

Start with the information provided. If a seller refuses to share the serial number or leaves out key details about the equipment’s condition, tread carefully. Missing or vague descriptions are often a sign that the seller either doesn’t know enough about the equipment — or doesn’t want you to know.

And here’s a bonus tip on serial numbers: Even if they’re missing, the equipment might not be stolen. The serial number is stored internally, and it can be found simply by scanning for Bluetooth signals (the serial number is in the Bluetooth device name). Here's what it looks like:

Also, pay close attention to the seller’s behavior. Poor communication is a major red flag. If it’s like pulling teeth to get straight answers, imagine how hard it’ll be to resolve any issues post-purchase. Similarly, unprofessional listings with low-quality photos, sloppy grammar, or inconsistent details can hint at carelessness — or outright dishonesty.

When in doubt, trust your instincts. If something feels off, it probably is. A good seller won’t shy away from your questions or hesitate to provide the details you need to make a confident purchase.

7. Purchase With Confidence

You’ve done your homework, asked all the right questions, and now it’s time to close the deal. But before you hit that “buy” button, let’s make sure everything checks out so you can purchase with confidence.

Start with price evaluation. Do some market research to get a feel for what similar equipment is selling for. A price that’s way below market value might seem like a steal, but it could be a sign of hidden problems — or even a scam.

It’s also important to think about shipping. Survey equipment isn’t exactly cheap or indestructible, so make sure the seller is committed to proper packaging. Look for listings that include details about how the equipment will be secured during transit, and don’t be shy about asking for insurance on high-value items. Free shipping? Even better.

By staying sharp and following these steps, you’ll not only score great gear but also avoid the pitfalls that come with buying used.

Bonus. What to Do After You Purchase Used Survey Equipment

So, you’ve found a great deal on used survey equipment. Now what? The real work starts once your new-to-you equipment arrives. Taking a few extra steps after your purchase ensures you’ll get the most out of your investment.

Start with an initial inspection. As soon as the package lands, give it a once-over. Check for any signs of damage during shipping and make sure everything matches the seller’s description. Don’t just power it on — test every feature you plan to use in the field.

Finally, think long-term with maintenance and storage. Establish a regular maintenance schedule to keep everything running smoothly. Clean it after every job and store it in a safe, dry place. Proper storage isn’t just about organization — it prevents unnecessary wear and tear, extending the life of your investment.

Taking these steps ensures your equipment works well, job after job.
