OLLIN Snapshot Spotter Adapter Size 13 - Magnetic Eyepiece Adapter

In this review the OLLIN Snapshot Spotter Adapter Size 13 is evaluated for hunters and wildlife observers who want a fast, reliable way to attach a smartphone to a spotting scope. The adapter's single biggest advantage is its magnetic Snapcase compatibility that removes fiddly alignment and mounting steps, making digiscoping quick in the field. The reviewer tested the adapter on compatible spotting scopes and found the low-profile compression fit and protective cap make it an unobtrusive, always-ready solution for capturing distant subjects with your phone when paired with the optional Snapcase.

Key Features

• Size compatibility: Size 13 fits Maven CS.1A/CS.1S and Athlon Ares G2 UHD 15-45X65, ensuring a snug fit on those eyepieces for consistent alignment.
• Magnetic connection: The adapter uses magnetic digiscoping technology to instantly connect to the Snapcase, cutting setup time and reducing missed shots from misalignment.
• Low-profile fit: The compression fit sits low on the eyepiece so you can leave the adapter mounted and still use the scope traditionally with your eye.
• Rugged security: An adjustable tether provides security during long-range hunting observations so the adapter stays attached if bumped.
• Protective cap: The cap keeps the spotter clean in wet or dusty conditions, preserving optics when the adapter is not in use.
• System workflow: Designed to work with the Snapshot system so users can connect, capture, and review images quickly once the Snapcase is added.

Who It's For

This adapter is aimed at hunters, birders, and wildlife photographers who already own compatible spotting scopes such as Maven CS.1A/CS.1S or Athlon Ares G2 UHD 15-45X65 and want a faster digiscoping workflow. It suits observers who value quick setup and who plan to leave an adapter on their eyepiece for ready use.

It is less useful for users without the Snapcase system or those using spotting scopes outside the listed compatibility. If your eyepiece size or brand is not listed, consider a different universal adapter or verify fit before purchasing.
