Offers 3 options to detect so can review watermarks, security strips and cotton rag paper. Can also see holograms and security features on many driver's licenses. I say light usage because it is built from plastic so a misplaced hand on top of the unit, accidental placement of a heavy object, or a fall to the ground will likely break off the light bar on top of the unit. Be aware of the unit's construction and it should do a good job. I have used it several times already. Can't say I found a bad bill, but that is a good thing to have ensured I took good cash. Only had unit for a shot time, but these have been around for a while. You can replace the detector pen if you accidentally lose it or let it dry out before it's time. The same company sells the widely used pen used for cotton rag paper detection. This unit will show holograms and other security features of Non-US bills but the security stripe detection alignment marks are designed for US bills. As a former banker, it works. Just would not put in a front line situation since is plastic. Review: Easy to use - It works! Easy to use and not too bulky to take with you if you are going to a cash sale transaction away from home or your own office. The only drawback is that you can only check one bill at a time, but that can take 1-2 seconds, so it's not too big of a deal. ## Features - WITH AUTO-SENSOR - INSTANTLY AND EASILY DETECT FAKE BILLS - Hands free activation – simply turn on once then slide bill onto the platter – the light is activated – no need to turn off – light will time out.

It combines three counterfeit detection methods in one device: a UV light for security features, a white light for watermark inspection, and a counterfeit detector pen that chemically tests the paper. **Q: What do I look for using the UV light on the Tri-Test?** A: The UV light reveals the embedded security thread in U.S. bills ($5 and up). Each denomination glows a different color and appears in a specific location on the bill. For example, a $20 bill will show a green glow in a specific vertical strip. **Q: Can I use the Tri-Test on non-U.S. currency?** A: It is primarily designed for U.S. currency and its specific security features. While the UV light might reveal some features on foreign currency, the pen and watermark light are unlikely to be effective outside the U.S. **Q: How accurate is the Tri-Test?** A: The Tri-Test is highly reliable for quick screening but not foolproof. It's a first line of defense that detects most common counterfeits. **Q: How do I use the white light feature on the Tri-Test?** A: The white LED light helps you inspect watermarks and microprinting on U.S. currency. Hold the bill up to the light to check for the watermark image (usually a replica of the portrait) and verify the presence and clarity of tiny printed details. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Light Use Option For Counterfeit Bill Detection *by J***R on December 15, 2023* Nice unit for light usage and occasional usage at events and other situations.
