Sea Adventurer with Kung Fu Grip
With fresh box art to reflect his new gripping hands, the Sea Adventurer with Kung Fu Grip (7281) dove into action in 1973. the example in the spin above came with a later version of the black rifle that has a strap of soft vinyl like plastic. this is held to the rifle with plastic nibs molded to the stock which tend to break easily. See the earlier version of the Sea Adventurer here.
As with the Commander, Land, and Air Adventurers, the Sea Adventurer got a bi-lingual box for Canadian kids.
