I have no experience with the Prostaff but I own 2 versions of the Monarch 3 and I have nothing but good things to say about both. Except maybe the Nikoplex reticle doesn't do it for me, but it works. Nikon makes some very nice glass for a good price.
Apparently you are right about there being two versions of the "Monarch 3" and lucky me got the early version....back it went. I don't know about anyone else but I think it's dishonest to sell two versions of a scope with one name. Guess I should edgumacated myself a little more on them before ordering....back to the drawing board.
If you're referring to the original Monarch series, they are a very good line of scopes as well, I'm not sure if they are as sturdy a build as the new 3 series though. But the legacy Monarchs get rave reviews as well.
There are actually 22 variations of the Monarch 3, different magnifications and reticles. I wouldn't say it's dishonest at all, Monarch 3 is just the name of the line of scopes with enough variations to meet different people's needs. I did a lot of research before hand to decide on the scopes I purchased. Due diligence I guess :/
Hmmm, that sounds like someone screwed up at the warehouse. In that case I'd be a little annoyed too, but hopefully you get what you originally intended.
I got educated by a Nikon Rep. There is the "Monarch III" and the new "Monarch 3". I was informed that Nikon is in the transition phase of changing between the older "III" and new "3".
Nobody made a mistake but me as I assumed they were the same scope.
