The PROSTAFF 3’s predecessor would be the venerable Spotter XL II which has proven itself over time to be a popular entry-model Fieldscope when it comes to nature observation activities such as birdwatching. Good to know then that the PROSTAFF 3 Fieldscope will maintain the honored features such as a similar bright and clear field of view of its predecessor, in addition to sporting a lightweight design that will enhance usability. Not only that, it will come in an airtight, waterproof structure as well as sport shock-resistant rubber armoring so that the PROSTAFF 3 Fieldscope operates well even under severe conditions.
