What it is best for

The Marten 420 suits hunters who want a wide field of view and an easy, traditional scope format. The 1.6x base and 25 mm lens make it well-suited to close-range work and fast acquisition on moving game.

• Detection range around 700 m

• 16 GB storage, photo/video recording and Wi-Fi

Trade-offs and who it is not for

With a 1.6x base and a shorter detection range, it is a close-to-medium-range scope rather than a long-distance tool; for more reach choose a 50 mm or 640 model. The 17-micron sensor is a step behind the latest 12-micron cores in fine detail.
