A tow assembly for an airborne electromagnetic surveying system comprises a generally circular support ring comprised of one or more inflatable tubes which, when inflated, form a semi-rigid inflated ring. Attachment straps are provided for attaching a transmitter coil to the support ring, and suspension lines are provided for suspending the ring from an airborne vehicle. Connection arms are provided for connecting and supporting a receiver concentrically within the ring. Preferably the support ring is comprised of a series of individually inflatable tubular sections, joined end to end, which, when all inflated form a generally circular semi-rigid frame. Alternatively the ring can be formed of a single tubular section shaped so as to form a circular semi-rigid frame when inflated. The support ring may have a diameter of between about 15 m and 25 m, although it is possible for the ring to have a diameter outside of that range. The inflatable tube or tubes preferably have a cross sectional diameter of between 200mm and 750mm.
