I recently started using the Bushnell Elite 2.5x Doubler. My prior experience is with the no-longer offered Eagle Optics 2.5x one. Both are made in Japan.
I do not know anything about how it performs with Bushnell binos.
What i can report:
My primary bino i use it with has a fov of 7.5 degrees. The doubler reduces that to about 3 degrees. It does not change the close focus distance of the bino.
As is true of any good doubler, it will amplify any underlying abberations in the bino.
With a high quality bino (in my case, the Nikon 8x32 SE) it provides a view similar to a spotting scope that is well corrected achromatic (non-ED) spotting scope, at 20x. Of course that bino is about as abberation free as they come, so YMMV.
