Sig Sauer 5k beyond 800 yards

[Adam S]

This might be an easy one but I figured I’d ask the forums. I’ve got an sig 5k range finder that I actually really like. Very simple to use and a decent app and has been reliable. I bought a revic br4 because of the ballistic solutions past 800 yards, which it does, but I absolutely hate how complicated and difficult it is to change settings. The app is terrible and honestly I don’t trust it as several times now I’ve had to reset it by taking the battery out because it failed to give me a ballistic solution.
So my question is can i do something with the 5k to get solutions beyond 800yards?
