Farming has its challenges. Agstar Financial commissioned us to brand this 10X foldout magnifier as a handy tool to inspect roots, fruits & leaves for damage caused by weather, insects & fungus. Blank magnifiers start at $4.95 which is separate from the cost of branding,; see pricing Details below.
The name "Agstar" is now associated with an EPA biogas recovery program using anaerobic digestors. Interestingly enough, scientists working in this area have used our ammonia, phosphate & nitrite/nitrate test strips with their bioreactors to monitor digestion efficiency.

Just the best on the market! Great quality, durability. I use this for more than 10 years with my students for field work.
We use this model in two introductory courses (a general geology course for engineers where 4 exercises cover minerals and rocks, and a mineralogy courses taken by a wide range of students in arts and science programs). Some students prefer its wider field of view to that of the other model we order from Indigo Instruments (their 17-mm glass lens, screw-hinged metal loupe). This loupe is durable, and can stand years of sharing among students learning their minerals and rocks in the classroom. Not designed to be worn on a lanyard, though.
