B&L and bushnell were divisions of the same company. They decided on a corporate name change so that all hunting gear would be under one banner. BAD IDEA.
So the excellent Elite 4000's and 4200's get tarred by a brand that also supplies the Sportsman and other Walmart wonders.
If you send it to your 'Bushnell' warranty depot, they will be serviced just fine.
The big difference was the lense coatings - Rain Guard. Optically and mechanically, they sure look/function the same. No idea if they changed any of the internal materials?
