The new Optisan PL spotting scope offers a great range of magnification (15-60x) while maintaining extra high resolution and brightness on high powers (50-60x) by utilizing the Hoya ED glass and the revolutionary 4x zoom eyepiece design. With a 400mm length and 1.85kg weight, PL is a very compact scope that easily fits into the backpack. Field tested and approved by the bird preservation & research team of Budai Salt Pan Wetlands: "We perform a monthly bird census and monthly guide along with TESRI (Taiwan Endemic Species Research Institute) in the Budai area, the new Optisan PL scope really helps a lot with our work and does its job for long-range observation. Our guide uses the smartphone adapter to integrate with the iPhone with the PL spotting scope and display the waterfowls to the participant so that they can both observe at the same time." |
