For any/all hunting trips, including Africa (especially for the open country in Namibia) get a very good range finding bino. Let your wife use the Pentax bino. If the cost is a stretch, then forgo the taxidermy AND the possible extra animal to fund the alpha bino/rangefinder combo. At least that's what I'd do. The Swarovski EL Range in 10x42 is excellent. Your PH may, or may not, have a range finder. His job is to find you a good trophy and get you close, but they don't always call out the range for the shot.
