Dri Mark Tri-Test Ultraviolet Counterfeit Detection System (351TRI)

I work PT and this comes in handy to detect fake money.Despite the low price, it works really well

Nice unit for light usage and occasional usage at events and other situations. 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.

The light and uv light make it impossible for the counterfeit money to get thru. I run a fast paced business. Where only twice a year, over a 4 day period, we take in lots of cash. Last year my employees took $1100 in counterfeit money in one night. That money passed the pen test. It would not have passed uv. So this year I have no doubt the counterfeiters will be back. (They come every year.) This time/event, they won't get over on us. I am so happy to not have to worry this time.

It does the job. It will be helpful when taking larger bills. Does the job, but feels cheaply made. It's worth the $35 I paid for it.

ES REALMENTE MUY SENCILLO, ME HUBIERA GUSTADO QUE LOS LEDS FUERAN DE MAYOR INTENSIDAD.

Very simple to use, works great. Detects the digital strip embedded on US notes. Uses violet light and also backlight.

The media could not be loaded. Cheaply made. The pen holder doesn't have a stop and so it slides in all the way and gets lost inside the machine. Only way to get it out is to take out the screws and the back off. Also the sensor doesny work. The lights stay on or off with the switch only.

Purchased this for work. Great tool to have when you question the bill. We don't use the pens cause they don't seem to be true

Canadian dollars can be identified as counterfeit by the WATERMARK, which can be easily identified with the naked eye.
