I love the connect . I shoot mine on 12mag and still have enough depth of field for hft ranges but I will argue there is still a very small amount of parallax error to contend with so do not become complacent with eye position.
Your eye still has to be in the same place evrytime even though your eye makes contact with the eyebell.
I also like the fact hat the eye touches the scope as I think it can help when shooting standers as there is another point of contact to help steady the rifle.
I'm after a connect sl if anyone has one , as there are none available till the new year (for us mere mortals)
