Here you can get the Signoscope T 3 watermark finder brand new WITHOUT power bank SAFE product number 9893.

The device works with 3 LEDs that allow repairs to identify repair grades, quality defects and paper irregularities in a fascinating new way. The device comes with a USB adapter and can be connected to the mains or a computer. You can also purchase a power bank (2600 mAh) item number 9894 for an additional charge, so that you are independent of other power sources. 

The LEDs are continuously dimmable

In addition, a stamp can be examined with 8 different light colors, which are also dimmable. This makes watermarks, paper differences or repairs easier to see depending on the light color.

For example, if you shine red light on a primarily red-based brand, the red brand color will be “neutralized” and you will see the watermark better.

The device works quite well. However, if you need to recognize very weak watermarks (such as war prints Germania), we recommend the more powerful Signoscope Pro!

Foreign buyers please pay attention to their country's import taxes. Shipping costs to the USA include import taxes since August 2025!
