The main body includes a handling region suitable for being handled by rig tongs, such that the instrument housing may be attached substantially along that handling region subsequently to its being handled. The handling region is located substantially centrally along the length of the main body. The main body includes at least one protective region having a larger cross section than the majority of the main body.
