I use the Forehead rest on both my NL 10x42 and the BTX spotting scope. For the binocular I find it helps stabilize the image and am glad I got it. I've gotten in the habit of using it all the time. Some people have written they don't find it useful. One factor to consider is the binocular mass. The NL Pure 10x42 is about 850 grams while the 10x32 lists as about 650 grams. In this range of mass I find the lighter glass is less stable, so I would guess in advance that the Forehead Rest would find use for me on a 10x32 if I had one. If you can test it at a dealer, a period of maybe 15 minutes of normal viewing activity without the Forehead Rest, and 15 minutes of normal viewing with it might let you learn how it works, or not, for you.
