    Q. Will this accept a technical pen attachment? What size should the shaft of the attachment be? (Rich U.)
    A. Unfortunately, the 961B does not have an attachment for a technical pen. However, we found that the P295 Universal adaptor will work with the beam compass and can be found here: Universal Adaptor.
