A reversible baffle plate for receiving and supporting a bottom hole survey apparatus on the interior of a directional drilling string is characterized by concentrically disposed inner and outer members supported one from the other by a plurality of webs. The webs cooperate with the inner and outer members to define a plurality of flow passages through the baffle plate. The first and second axial ends of the inner tubular member are each adapted to receive and support the lowermost axial end of a bottom hole survey apparatus.
