Buying a Golf Launch Monitor: What to Look For
Used

Not all used marketplaces are equal. Here's where to look — and the trade-offs of each.

eBay: The largest selection of used launch monitors. Buyer protection is strong (eBay Money Back Guarantee covers defective items). Look for sellers with 98%+ positive feedback and listings with clear photos of the actual unit. Avoid listings with only stock photos — you want to see the specific unit you're buying.

Facebook Marketplace: Often the cheapest prices because sellers want quick local sales. The downside: no built-in buyer protection. Always meet in person, power on the unit, and test it before paying. Facebook Marketplace is best for local deals where you can inspect before buying.

Golf WRX Classifieds: The golf enthusiast's used market. Sellers here tend to be knowledgeable golfers who take care of their equipment. Prices are fair (not as cheap as Marketplace, not as high as eBay). The community polices bad actors. A solid option for higher-end used units.

Amazon Renewed: Amazon's certified refurbished program. Units are inspected and come with a 90-day Amazon Renewed guarantee. Prices are typically 15–25% off new — not as deep a discount as private sales, but with the safety of Amazon's return policy. Best for risk-averse buyers.

Before you hand over money for a used launch monitor, verify these five things. Skip any of them and you're gambling.

1. Firmware Version: Ask the seller what firmware version the unit is running. Check the manufacturer's website for the latest version. Outdated firmware can mean missing features, compatibility issues, or in worst cases, a unit that's been locked out of updates. If the seller doesn't know or can't check, that's a yellow flag.

2. Battery Health: For battery-powered units (Garmin R10, Mevo+, Rapsodo), ask how long a full charge lasts in actual use. A Garmin R10 with a healthy battery should last 8–10 hours. If the seller says "a few hours" or "I haven't used it much lately," the battery may be degraded. Lithium batteries degrade with age even when not used.

3. Sensor/Camera Condition: Inspect the sensor window (radar units) or camera lens (photometric units) for scratches, cracks, or haze. Even minor damage to these components can cause data errors. On camera-based units, ask to see a test shot — blurry or inconsistent readings suggest camera calibration problems.

4. Warranty Transferability: Most manufacturer warranties are not transferable to second owners. Garmin, Rapsodo, and FlightScope all tie warranties to the original purchaser. This means you're buying with no manufacturer support if something goes wrong. Factor this into your price expectation — used should be significantly cheaper than new to account for zero warranty.

5. Subscription Status: Some units have paid features or subscriptions tied to the original owner's account. Ask if any active subscriptions transfer with the unit, or if you'll need to set up new accounts and pay from scratch. For units like the SkyTrak+ where the subscription adds significant functionality, this matters.

Walk away from any used launch monitor deal if you encounter these warning signs.

Missing Accessories: No charging cable, no original box, no carrying case. While not deal-breakers individually, missing accessories often signal a unit that's been heavily used, poorly maintained, or potentially stolen. At minimum, you'll need to buy replacement accessories.

No Original Box or Proof of Purchase: Without proof of purchase, you can't verify the unit's age, check warranty status, or confirm it wasn't stolen. Some manufacturers require proof of purchase for firmware updates or service. If the seller has no receipt and no box, proceed with caution.

Seller Won't Demonstrate It Working: If a seller refuses to power on the unit, connect it to an app, and hit a few balls while you watch — something is wrong. Any honest seller should be happy to show the unit functioning. "It worked last time I used it" is not a demonstration.

Firmware Locked or Outdated: Some units can become locked to a previous owner's account or fall so far behind on firmware that they can't update. Ask the seller to factory reset the unit and update firmware before purchase. If they can't or won't, you may be buying a brick.

Price Too Good to Be True: A Garmin R10 for $150 or a Mevo+ for $600 should raise immediate suspicion. These prices are well below market for working units and often indicate stolen property, broken units, or scams. Check completed eBay listings to understand fair market value before any purchase.
