Well as someone who can knock down 10 in a row on the clay pigeon range (ok, not every time, lol) and yet can miss ducks with extremely high consistency..... so my point is, I think a lot of us could benefit from trying some different shotgun sights.
The sights should NOT be used as a replacement for practice, and are not really for "aiming"... and follow through, mounting technique, etc are all very important. However, a lot of people (including me) have problems with eye dominance. And as mentioned, some of the angles and crazy stuff we hunt in are not even close to the shooting range conditions. Add about 23 layers of clothing.... wind.... croutching down in the blind till the last second... getting suprised, out of position.... and some adrenaline... not to mention unpredictable ducks, LOL
Try some of the fiber optic sights. Some I really like, some I don't. Ever try a one-eye blinder on the on top of the magazine? It can help a LOT with eye dominance problems. Also, the large ring type rear sites can be helpful, they helped me realize I was not mounting the gun level enough and shooting way over a lot of birds. they also help with judging lead distances.
I am hesitant to try new things, yet every time I do, I am like, why didn't I try this long ago?!?!??!! LOL
