Abstract: The lance is composed of a hollow tubular shaft having a cap connected to one end thereof. The cap is disengageable from the shaft for allowing access to the interior of the shaft. The cap is connected to a resilient band for carrying of the spear and propelling it through the water. The opposite end of the spear contains an insert having an axially running socket located centrally thereof for accepting a spearhead. The spearhead is held within the insert by surgical tubing which covers a portion of the insert and a portion of the spearhead. The surgical tubing also provides an airtight seal between the spearhead and the insert. The spearhead is, therefore, held within the insert by a frictional engagement with the surgical tubing as well as the suction created between the spearhead and the insert socket.
