Question: I just rceived this sight today and cant find this feature, (Mechanical Rheostat Feature to adjust pin brightness). Can somebody explain it to me?
Document: I got the sight a few days ago and sighted it in. The tapes that come with the sight are extremely accurate. also the pin is one of the brightest ive ever seen. this is a great sight and i would recommend it to anyone.
This thing will actually make you a better archer. It is very easy to set up and sight in. I routinely practice at insane distances now just for fun. At 70+ yards, I'm hitting the 3D target (in the right place) every time. No way I could ever do that with my old multi pin sight. Just buy this thing. You can thank me later.
I was sent an open package with no mounting bolts. Poor handling of a good product. I was excited to use it today but i have to take it to a local shop to see if they have the hardware to set it up.
Great sight. It takes some getting used to in the heat of the hunt though. I recommended this product to friends
I bought two of the Optimizer sights, and both sights where easy to sight in, and easy to use.Awesome bow sights!
I am very pleased with this sight. Couldn't he happier. Well worth the money and should last a lifetime just like its 100 percent warranty. THANKS!
Best bow sight I have ever use. Up to 80 yards with my Mathews Z7.Highly recommend it to any bow hunter.Love it
Put the sight on the bow. Got it all tuned in and I was good to go. Very good sight I'm very happy with it can't wait to pick up a lens kit for it to see how that works out!
Being optically challenged and using a hind sight for the last 11 years I was skeptical if this sight would work as good as the reviews that were made for it. I thought it was pricey but after looking at several other sights this one was not only a quality made sight, its price was very competitive. Remember I hadn't bought a sight in 11years so I was way behind in price and technology. After installation and sighting in, I can almost shoot as well as I did 15 years ago.
I purchased this as a gift for my boyfriend and it is exactly what he wanted. He loved it and was excited to try it out!
Answer: yes
