The 4k interactive Book Trailer is a series of pictures from Gold, Coins, and Treasure video book. The video book contains over 30 years of Treasure Hunting experience theory and practice from Goldfinders. The World’s first tutorial style video book also has the capacity to stop and allow the reader to take time to read the wealth of new and original information incorporated within, along with the real 4k video quality. The video book also has viewer controlled stop start knowledge self check tutorial at the end . I believe this learning style is completely original, entertaining and full of interesting facts and a wealth of information on Modern Treasure Hunting.
