      You are only going to find two types of watermark detectors on this page. Watermark fluid and the Safe Signoscope. The reason  for this is that they are the only watermark tools I have found that work. There are many other "detectors" with big claims that do not live up to these claims and I will not promote any supplies that I do not believe in.
     Even at that, do not believe that the Signoscope is a miracle worker, detecting watermarks is a very difficult job and only experience will make you proficient at it.
    For the normal collector I recommend just purchasing watermark fluid as it does a better job at detecting watermarks than the Signoscope. The Signoscope is good for people working with a large volume of stamps where it can save money over using large quantities of fluid.
     The watermark fluid I sell here is safe for all stamps. It will not adversely affect the stamp's gum or ink.
