Scientific Advisory Services now supplies an affordable x 10 hand lens for growers, crop scouts, agronomists and students. A hand lens is essential for in-field examination of many small insects and mites as well as being useful to detect disease organisms.
The best feature of this hand lens is that it includes two bright LED lights for illuminating the subject being examined. This removes the necessity to move to a brightly lit area, remove your hat or stand so that you are not shading the subject. This magnifying glass is supplied in a protective plastic box for safe storage and includes a key for replacing the battery.
The hand lens is protected when not in use as it swivels back inside its handle which then forms a neat cover. There are no sharp edges and it can be attached to a lanyard and kept handy in one’s top pocket.
