Straight erect prism

[blind pew]

Does anyone know where I can obtain a bushnell straight erect prism for terrestrial use.Also has anybody used one of these.Are they any good.Does anyone else make them.Any help would be appreciated please.

Not sure about Bushnell, but Vixen makes a terrestrial erect image adapter. It probably uses roof prisms judging by its shape. I'm not entirely sure what they mean by magenta coating.

Is there any reason why you don't want the 45 deg erecting prism?

Thanks for that.It is not that I do not want a 45 deg prism.I have one of those but for viewing on a short tripod on the top of my car a straight one would be much better.
