A pocket magnifier or loupe is a useful addition to any field kit. It will aid in the observation and identification of insects, bugs, plants, rocks and any other specimens that are difficult to observe with the naked eye.
This Hilkinson Ruper Triple Hand Lens has three 20mm lenses with 3x, 4x and 5x magnification, giving you the option to observe your specimen at three different magnifications. When not in use the lenses can be tucked away inside the compact and robust metal casing, keeping them protected from scratches and bumps.
Hilkinson Ruper Hand Lenses are also available with a single or double lens.
