Discover the hidden rarities in your collection with this best selling handheld tool. The Stanley Gibbons Detectamark Spectrum makes it even easier to discover the hidden rarities in your collection. This battery powered device operates via pressure applied evenly to the stamp by means of a recessed screw in the base of the device (AA batteries not included). It is simple to use and the multiple colour settings and adjustable light source, unique to the Detectamark Spectrum, provide additional help when identifying more difficult watermarks.
It even shows up watermarks on modern stamps printed on thick, chalk-surfaced papers with full gum - the ones that other detectors fail to identify.It is clean safe and very effective, without the use of chemicals and solvents and also helps to detect minor damage, such as thins, tears or repairs
