After doing some research on night lights, I have decided to buy one of the Optronics products. I see that they make a 100 yd..a 250 yd...and a 350 yd (which has an adjustable beam feature). Who has purchased which model and why? Is the small 100yr light adequate enough? Are these good products? Do they do the job? I plan on placing one of these on my 22 mag. I missed the opportunity to shoot a coyote the other night because I was fumbling with my portable hand held light in one hand and my rifle in the other !! I've decided that a rifle mount is best. ALL input is appreciated....Thanks.....
