OLLIN Snapshot Spotter Adapter Size 02 - Magnetic Eyepiece Adapter

In this review the OLLIN Snapshot Spotter Adapter Size 02 is judged as a practical accessory for serious digiscopers who use compatible spotting scopes. The bottom line: it solves the most common frustration with smartphone digiscoping by using magnetic Snapcase technology (Snapcase sold separately) to speed up alignment and make captures more reliable. Reviewers will appreciate that it remains low profile on the eyepiece so the scope can still be used normally with the eye while the tether and protective cap add field-ready security for hunting and wildlife observation.

Key Features

• Compatibility: Size 02 fits several popular spotting scopes including Swarovski ATS/STS (2022 and older) and Kowa TSN-99/88/77/66, ensuring a secure fit for those models.
• Magnetic connection: The adapter uses magnetic digiscoping technology to instantly connect to the Snapcase, eliminating repeated adjustments and alignment frustration during a shoot.
• Low-profile fit: The compression fit design sits low on the eyepiece so it can be left on the scope and still allow normal eye use without removing the adapter.
• Rugged protection: An included protective cap keeps the eyepiece clean from dust and weather, helping maintain image quality in harsh outdoor conditions.
• Security tether: The adjustable tether provides an extra safeguard during long-range hunting observations so the adapter is less likely to be lost during active use.

Who It's For

The adapter is aimed at hunters, birders, and wildlife photographers who already own a compatible spotting scope and want faster, more consistent smartphone digiscoping. It is especially useful for users who switch between using the scope with an eye and quickly capturing a shot with a phone, since the low-profile design supports both workflows.

Those who do not own a Snapcase or who use spotting scopes outside the listed models should look elsewhere or verify fit before purchase, because the magnetic system requires the separate Snapcase to realize the quick-attach benefit.

Pros & Cons

Pros

• Fast magnetic attachment to the Snapcase means fewer missed moments from slow alignment.
• Leaves on the eyepiece without obstructing normal eye use, so switching between viewing and capturing is seamless.
• Built for field use with an adjustable tether and protective cap to keep the spotter clean and secure.

Cons

• Requires the separate Snapcase to use the magnetic connection, which is an additional purchase.
• Compatibility is limited to specific scope models, so users must confirm fit with their eyepiece.
