Software for search in binary files?

I need a software that would search trough bunch of binary (non-textual) files for a sequence of bytes, e.g. FF00FFA0EE

It should be able to be given a folder to search, and filter for files, e.g. *.xyz, and of course the pattern to search. Quite simple.

It has to be a FREE software!

I was looking at internet, but nothing promising. Found something called PowerGREP, but it is not free, and it is unbelievable unintuitive… I can't spend two days reading its help in order to find how to perform such a simple request…

FileSearchEX might do it. I just told it to look in an .exe and it did ... I don't know if you could convert your byte sequence to a string because that may be what it really needs.

I've been using this for years.
