POORMANS TABLET PMT-A7 The Poorman's Tablet (PMT-A6) was originally developed in 2017 for Special Operations Forces to provide a safe, secure and sterile device for taking notes, recording information and sketching in adverse weather conditions, low light and hostile environments. With an additional 5 more years of research and feedback the PMT-A7 was subsequently developed. Made from advanced materials the PMT-A7 is now easier to clean with no 'ghost writing' effect. Highly waterproof, long lasting and it does not deteriorate after each use (remains matte) so will last for many years of service. The PMT-A7 has a surface area of 74 x 105 millimetres. In inches, this is 2.913 x 4.134 inches. There are 2 TYPES: TYPE A features a 15mm slot that when used with the Tactical Equipment Speed Tether (TEST) - NOT INCLUDED the PMT-A7 is held in a fixed vertical position. TYPE B features a 10mm hole that when used with the Tactical Equipment Speed Tether (TEST) - NOT INCLUDED the PMT-A7 can rotate 360 degrees. Both types are supplied as Single (1 x PMT-A7) or Double-Stack (2 x PMT-A7) for the same surface area as the original PMT-A6 (105 x 148 millimetres / 4.134 x 5.827 inches) that will fit in most pockets or inside an A7 notebooks to counter the forensic recovery of your notes, even when you have removed pages! Safe... The PMT-A7 does not produce heat, flames or sparks so it can also be used safely in areas of combustible gasses or liquids. It is also completely non-magnetic and non-metallic. Secure... We all know that electronic devices are prone to 'leaking information' but paper is not always the best option to 'go dark'. Writing on notepads or other paper surface creates indented impressions on the paper beneath the original writings. The indented impressions are not always visible to the naked eye and have been recovered from up to seven layers of paper. Documents that may contain indented impressions not visible to the naked eye can be visualised through the use of an Electrostatic Detection Device (EDD) such as the Electrostatic Detection Apparatus (ESDA). An EDD uses applied charges and toner to visualise areas of indented writing, making them visible to the eye. Even documents that were shredded or burned may prove useful if reconstructed. If you have to take a note on paper you can place the Poorman's Tablet underneath to stop an indented impression on the other layers of paper. When you erase a note from the Poorman's Tablet it is gone for good with no risk of leaving an indented impression that can be recovered at a later date. The Poorman's Tablet ensures you are always working from a 'clean slate'! Sterile... As with all our special products the PMT-A7 is free from manufacturers stamps and marks. Chalk Pen (fine point) also available: High quality water based ink delivers clean, flowing fine lines that go on smooth and quick dry within minutes. The marks can be erased easily by wiping the area with a damp cloth or hand. Odourless and non-toxic For writing in the rain or underwater we recommend Staedtler Lumocolor Permanent Glasochrom pencils.
