How much monoculars cost depends on the particular monocular and its features. But, generally speaking, one of the best aspects of monoculars is their affordable price point. Monoculars are often less than 50% of the cost of a decent pair of binoculars. On the lower end of the scale, you can pick up a monocular for around $20 for the budget-conscious buyer. For a premium monocular, expect to pay up to $1500 for your optic. However, on average, for a high-quality monocular that won't break the bank, a median price point of $100-$300 will net you an excellent monocular that will last you for years to come.
