In the high end sight market some scopes have cut outs around the pin to let light in and some don’t and some companies offer vented and non vent housings for their scopes. Why is that ? I would think that one is better than the other and that they would all be made the same. My HHA has no cutouts and my friends Sure-loc has major cutouts and CBE has the same scope with and without cutouts.
Probably has to do with how the fiber optics is laid out on the sight. After taking a glance at both the CBE & Surloc, most of the optics is only available to light at the pin. On the HHA’s the optics are laid out on the outside of the scope where light can be absorb throughout. This is way I think the HHA’s have one of the brightess pins out there.
Called Axcel and talked to a sales rep and he said that cutouts letting light in is better in low light or indoors and solid housings are better in bright light especially with lenses because of the glare.
