Refurbished vs New CAT4: Which Should You Buy?
For most buyers a refurbished CAT4 is the smarter purchase. A properly reconditioned unit is fully calibrated, carries a warranty, and performs identically to new while costing far less, often around half. New only makes sense when you need the very latest data-logging and fleet-management features across a large team.
The CAT4 has been the UK industry standard for years, which means the used market is deep and the refurbished option is genuinely viable rather than a compromise. The key is what "refurbished" actually means.
What does a proper refurbishment involve?
There is a real difference between "used, sold as seen" and a professionally reconditioned unit. Our refurbishment process means each CAT4 is inspected, serviced, repaired where needed, fully recalibrated to specification, and supplied with a calibration certificate and a 12-month warranty. You get a unit that is ready for site on day one, with the paperwork to prove it.
Does refurbished perform the same as new?
Functionally, yes. A calibrated CAT4 detects to the same specification whether it left the factory last month or three years ago. The electronics are robust and the locating performance does not degrade with age once the unit is serviced and calibrated. What you give up is purely cosmetic wear and, on older models, the newest software features.
When is new worth the premium?
- You are standardising a large fleet and want every unit on the latest firmware and data-logging platform.
- You need specific new features such as the most recent cloud calibration or fleet-management integration.
- You want the longest possible service life from a single purchase.
For a one-or-two unit operation, those advantages rarely justify the extra cost.
