Huge Upgrade

by charlieprit23, from GA, United States Written on July 24, 2025
This is a big upgrade that I have been wanting to make for a while now. I went with this because of the power and clarity. It also has a ballistic calculator that takes in to account the weather which makes it very accurate. You do need to use an app for the ballistics and a few other features, but it is actually really simple to use. I let everyone I hunt with try it out and they have all loved it.
Pros:
  • Accurate
  • ballistic calculator
Cons:
  • None
Would recommend: Yes

Sleek and Powerful

by ricksoren6878, from SC, United States Written on June 24, 2025
After several outings I can confidently say this scope is a serious performer. It is very clear, even in fog or dense brush. Picks up even the smallest heat signatures, which has been great for spotting game at long distances. The laser rangefinder is fast, accurate, and easy to use. The ballistic calculator is amazing for long-range shots. It adjusts for distance, bullet caliber, and even weather conditions. Even the app is very easy to use and understand. I recommend this to everyone I talk to and show it off every chance I get.
Pros:
  • ballistic calculator
  • range finding
Cons:
  • None
Best Used for:
  • hunting
  • Night spotting

Can't Wait

by HeatHunter, from TX, United States Written on June 12, 2025
I just received this scope and have only been playing with it so far and can't wait to use it. So far it has been really easy to set up and have just been looking through it in my backyard. Should be very fun and I am excited to get out and use it.
