Spacer Size

 The Optic Spacer: is NOT a completely universal part. The Optic Spacer is dependent on which optic you choose to use your adapter on. Each spacer has a range of sizes it can be used with, so you can use your spacer on more than one single optic! Select one of the available options in the drop down using the chart in the pictures as a reference. 

IMPORTANT: If you do not see your specific optic listed, select custom then enter your optics Brand, Model and eyepiece diameter in the order notes at checkout.

NOTE: The OG 2.0/3.0 comes with one spacer when you order it. This is an additional optic spacer that works with both the 3.0 and 2.0 versions

Works as described

Super simple. I love how minimal the adapter that goes on the phone case is. I hardly notice it. The piece to attach to the spotter fits well, a little lose but have not tried the smaller rubber band. Not a big deal, still works.

Only complaint, I would love a stronger magnet, seems like that’s super doable. Also, maybe a little better locking or engagement similar to how the vehicle adapter cut out matches. Again, that’s being picky. A stronger magnet and this is 5 star all day long but I want to be clear it does work just fine as is! It’s also about the most affordable option in this market and made in USA!

Best I’ve used!

I’ve used onglass for a few yrs and it’s the easiest one out there to use. I like that I could just throw magnet on phone case and go. I actually bought a cheap phone case (blaze orange in case I set phone down or drop it while a field) to stick magnet on and use when taking pics. Pics & vids are always perfectly centered.

I’m fairly new at hunting I bought me some binoculars and spotting scope I was having trouble trying to figure out what I needed. I shot the company and Email they sent me back a link. I had my stuff in a week. I love the way it works. It’s a lot easier for me to use my spotty scope now thank you guys. Appreciate the service. Appreciate the quality.
