MACHINE TRANSLATION (not authorised yet)

It's enlarged in terms of functionality The EKO-BIODevice. It is a very useful teaching aid of a compact type, i.e. many devices combined into one logical whole. Just like The EKO-BIO is a set of interconnected devices: a compass, two different pairs of magnifiers (movable, overlapping), a space for observing specimens closed with magnifying glasses on both sides, binoculars, a stereoscopic magnifier, a whistle and a heliograph and additional elements: a universal sundial model, a quadrant, a torch, Morse code. We highly recommend this multifunctional and inexpensive scientific aid.
