In the proliferation age of diving in the late 1950s and
early 1960s diving innovators manufactured different products for sale in
the dive shops. Jack had a product line called 'Hi-Sea'. One of the things
he manufactured was a small speargun. This gun was sold in two sizes, 24"
and 40" length. The dive shop owners told him that these smaller guns would
sell the best. Although Jack and his associates were true big game hunters
with powerful equipment, smaller guns were most marketable. They could be
used by anyone in any body of water, including lakes. Please see an image
of a well-used version of the Hi-Sea speargun.
This production speargun had a handle made from fiberglass
reinforced plastic and nosepiece made from aluminum. The trigger mechanism
was one-piece. A single line release can be seen on the top front, left side
of the handle. Jack's later spearguns would release the line with two prongs,
one on each side of the spearshaft, that dropped when the trigger was pulled
. The foiled hand grip and trigger guard is characteristic of Prodanovich
designs. The shape was similar to Jack's father's pistol.
Speargun handles and nose pieces by different manufacturers have unique design. This is one of the features which enables us to trace the origins of the design.
