Tripod adaptable binoculars have a standard 1/4-20 female thread to attach to tripods or shooting rests for the utmost stability. Tripod use is a must for binoculars with 12 power or more, and is useful for any lower magnification, as well. High powered binoculars are extremely difficult to hold steady, and can cause headaches due to eye strain. Performance is poor without a rock solid mount. A binocular tripod will give you the stability you need for clear observation!
