I have used both rangefinders a little bit and for my uses, the MONARCH 3000 Stabilized gets the nod. I have been using Nikon's first stabilized rangefinder, the 7iVR for 2 years now and love it. Hunting and some longrange shooting to 1000 yards is my preferred use. I have ranged deer to 700 yards with my 7iVR and I can assure you the MONARCH 3000 Stabilized is better and faster. As many of you know I do some freelance work with Nikon but I promise you my comments will always reflect my hands on experiences and I do no sales at all.
