The only difference between the ProDot and the ProDot Max Duty is in the design. As far as characteristics go this sight is just as great. It’s extremely durable as it is manufactured from aluminum (except for the front optic, which is a very tough plastic, and the rear optic, which is a glass lens). It does not require batteries, which in long term saves you money. The dot is very clear even in low-light conditions. The sight is very easy to adjust and zero and is also very steady so once you zeroed it right it will stay in place. Here’s the provided information about this sight:
“The Armson ProDot sight is the king of optical illusion sights. One eye sees a black circle with the red dot in the middle. The other eye sees the target and when you’re brain puts it all together you see your target with a dot on it.”
Just like the ProDot Max Duty the ProDot will take a little time to adjust to. It requires both eyes open to see the red dot on the target and this is something quite confusing for some people. With the time you’ll get used to it but this is something worth considering before making the purchase. The only real downside for this sight is that the screws, snap rings and mounting plates are made of regular steel and can get rusty with time. It would have been nice if they were made of stainless steel, but they’re not. Anyway if you keep your sight clean and take care of it properly I don’t think you’ll have problems with rust. The sight is quite expensive and probably not something anyone can afford, but it’s worth every penny. You can find it for about $70 and I’m sure you’ll be very happy with it if you decide to get it.
