I have never owned a scope with an illuminated reticle, but as I get older and my eyesight is not as sharp as it once was, I figured I would try one. Have always used the standard duplex or B&C reticles.
I ordered my new Leupold VX-5HD 2-10x42 with the Firedot reticle for my 338 Federal.
I believe that in the thick brush and/or under low light conditions it will aid in placing the crosshairs on a bear or moose for better shot placement.
The thought of a battery failing is somewhat bothersome, but I will carry spare and can replace as required, and as in my rangefinder, I start every season with a fresh battery.
I will see (pun intended! LOL) once my rifle is complete.
