The first optic-electric Watermark Detectors


Still the ONLY one on the world-wide market!

Make your dreams come true!

For a long time now you have been dreaming of being able to check all of your stamps for watermarks in a simple way, quickly, precisely, and without endangering your stamps. This is no longer a dream. The SAFE-Signoscope is reality! The units are worth far more than what they cost. One single newly discovered watermark or a newly identified watermark variation can make up, several times over, for the money spent to buy a SAFE Signoscope. Watermark or no watermark, falling or rising. Well, let's get out the watermark fluid... No, not any more! The "steamboat age" is past. From now on you will check for watermarks simply and precisely and without taking any chances of damaging your expensive stamps.

Discover your treasures!

Scott No. 439 or 476A? The stamp catalogs will show you the difference, and the SAFE Signoscope will bring it to light. You suddenly discover treasures you did not know you had! The difference could be in the thousands of dollars. It is so simple, and it works so quickly. You simply place your stamp into your Signoscope. If there is a watermark, it will show, even on yellow or orange stamps. Take your time studying its fascinating contrasts and its many details. You will discover watermarks which you would have been unable to detect with "yesterday's" methods. Learn to distinguish paper irregularities, repairs, grills, hinge marks, added margins, etc.

Are there any hidden treasures in your collection?
