Just What the Doctor Ordered

by Spike Cover

November 2019

Many of us have paid $200 or even more for a decent microscope.  They are nice tools and we use them to diagnose parasites very effectively.  However, they are not all that easy to carry around and some need to be plugged into a power source.
I recently discovered a pocket microscope that serves our bug hunting needs very well and doesn’t cost an arm and a leg.  It is very portable, has excellent optics, a built-in light source, accepts slides and cover slips, and even has a provision to adapt a smart phone such that still pictures and videos may be captured.  It has nice focusing ability and zoom magnification from 100x to 250x, with which we can see all the normal microscopic Koi parasites including Costia.  What it doesn’t have is a mechanical stage.  So, you need to manually manipulate the slide to scan it.  However, for less than 1/10th the price of a traditional microscope, this gizmo is near perfect for our needs.
For those on a limited budget or just want a scope that’s easy to take on pond calls, this little gem provides virtually everything you need.
