PROSTAFF 3 Fieldscope

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to announce the release of the PROSTAFF 3, a lightweight and compact Fieldscope with an excellent portable design that facilitates relaxed, easy and agile birdwatching.

The PROSTAFF 3's predecessor is the Spotter XL II, a popular entry-model Fieldscope for nature observation activities such as birdwatching. The PROSTAFF 3 Fieldscope has the same bright and clear field of view of the earlier model, while its lightweight design further enhances usability. Its airtight, waterproof structure and shock-resistant rubber armoring ensure superbly reliable durability even under severe conditions.

The PROSTAFF 3 Fieldscope comes with a compact tripod and carrying case included, making it an even more convenient entry model for easy nature watching.
