This hub will give the G1 bipods the ability to have the newly added G2 feature, the throw lever, as opposed to the G1 thumb wheel. It will also allow Arca Swiss or Arca style rail users the ability to use Accu-Tac bipods without the need for an added adapter. It is compatible with any G1 or G2 bipod legs with the exception of the HD-50 models.
