The Carson Clip-N-Flip Magnifier helps anglers handle close-up tasks with better clarity when tying small trout flies, threading line, pinching split shot, or working on detailed terminal tackle at the bench or on the water. A sturdy clip attaches near the bridge of nearly any pair of glasses, giving you a convenient flip-down magnifier that stays close at hand instead of taking up space in your vest or pack. Two models cover different magnification needs, with the OD-10 offering +2.25 diopter power and the OD-12 offering +3.00 diopter power, and each includes a protective pouch for storage between trips. Available in two models: OD-10 with +2.25 diopter magnification OD-12 with +3.00 diopter magnification Dimensions: 2.4 x 1.5 x 4.7 inch Main lens material: Acrylic Lens type: Single magnification Great for fly tying, knot work, hook changes, and other close-detail fishing tasks Sturdy, durable clip attaches near the bridge of nearly any pair of glasses Includes a protective pouch for storage and travel Model Diopters Magnification Main lens focal length (mm) OD-10 +2.25 1.5x 500 OD-12 +3.00 1.75x 333.3
