The SwordSlasher Adjustable Harpoon© (Patent Pending) was developed by a serious offshore fisherman who was looking for an easier way to land large Tuna, Swordfish and Sharks.  The traditional ways used to subdue and boat these magnificent game fish consists of 3 things: a flying gaff, straight gaff and a harpoon. The straight gaff works fine to boat small to medium sized game fish, but on larger fish it is usually used as a secondary securing gaff.  On a larger game fish the standard way to boat the fish is to hit it with a flying gaff and then secure it with a rope or a straight gaff and lift the fish into the boat.  The flying gaff is not easy to use and it requires knowledge and skill to plant the hook correctly in a fish.  Quite often the head of the gaff isn't secured correctly to the breakaway pole and it falls off the pole before the fish is at the boat making it an obsolete landing tool when the fish has just been leadered in and is at the boat.  This is the most critical point of the whole battle and a lot of fish are lost at this final stage of the fight.    A harpoon is used on a stubborn fish that will not come to the boat and sits just off the port or starboard side of the cockpit, or stays down under the boat out of range of the 2 types of gaffs.  The dart head is secured to the harpoon shaft via a rope and the whole harpoon can then be thrown at the fish, or stabbed into the side of a fish and ran through the fishes body.  The dart head then come off of the harpoon shaft and turns sideways giving the angler control over the fish and enabling him to bring the fish to the boat and land it. After many offshore fishing trips where a traditional harpoon was used instead of a gaff to secure and land a large game fish, the SwordSlasher Adjustable Harpoon© (Patent Pending) was conceived.  The problem with a traditional harpoon is it comes in two sizes, 6 and 12 feet.  Each segment is approximately 6 feet long and they screw together to form the longer length.  Often the 6 foot length is too short to use on a fish that is just out of its limited 6 foot range and the 12 foot length is often too long and difficult to handle - especially if you are in a smaller fishing vessel.  The long harpoon pole and rope attached to the dart tip often get tangled up in the outriggers, radio antennas, or hit the fishing rods and people in the cockpit.  These situations are dangerous to the anglers and crew and can cause a fish to be lost right at the boat. The SwordSlasher Adjustable Harpoon™ (pending) is the perfect weapon and designed to subdue the fish at the most critical moment of the fight.  The harpoon has 5 different lengths - it can extend from 8 feet to over 12 feet instantly.  This unique feature definitely makes it the ideal choice over a straight gaff, flying gaff or traditional harpoon for securing a fish.  No matter what situation the crew may encounter while trying to leader a fish to the boat, this harpoon can be extended to the length needed to end the battle and secure the fish quickly.  The adjustable harpoon can also be used in the traditional manner and be thrown at a fish.  Either way, the adjustable harpoon has proven itself to be an effective weapon for landing big game fish offshore.
