If you’re buying one of the best rangefinders, you’ll spend $300 to $600. A top-of-the-line sight will be in a similar price range. At the top end of the combined cost, you’re pretty close to an A1i Pro. Then, if you take into account the added features, you can justify the cost. But, if you already have a top-end rangefinder and just need sight, it becomes a more difficult decision.
