I have a pair of Engage binoculars from Bushnell and I speak highly of their optical performance.
A friend of mine decided to buy a pair after looking through mine and was disappointed with the view.
After looking through his pair and sharing his concern, we found he didn't buy the Engage model but the Engage DX model, thinking it was the 2019 new model (as shown on the Bushnell website).
Long story short, the Engage DX line has retained a similar name but dropped : the ED glass, the phase coating, the ultrawide band coating, and the locking diopter.
Beware that the description on the Bushnell website is misleading and full of false information (says the DX model has phase coating and ED glass but this is not the case)
Be careful if buying one. IMO the 25% price difference is not worth the downgraded features.
My friend will return his pair.
