Articulated Wishbone or other wise known as a french articulated wishbone. Another name used is Bridles Articles: Converting a spear for dyneema Different bridles
Bait up Often Sea urchins broken together to attract fish, or bait fish that might be used to bring in other fish. Articles: Hunting Snapper
Bommy Not that common in New Zealand but a rock formation or in the Tropics a cluster of coral that rises up from the sand
Bottom time This is with reference to time the diver has spent on the sea bottom. Articles: Breath hold
Break away A speargun setup in such a way that when it's fired the spear can detach from the gun but still be linked to the floatline.
Bridle Also known as Wishbone, which hooks into the notch of the spear. Types of bridles are Dyneema, french articulated, wire, wire braid.
Burley Fish remains dumped off the back of a boat.
Carbon barrel The tube that makes up the main part of the gun. The most common substance used to make up Euro styled guns is Aluminum.
Closed cell
Constrictor knot Often used on rap around rubbers where the bridle is inserted inside the rubber slings.
Dyneema Often used as bridles in spearguns. Although it has a very high breaking strain it's because of it's abrasion resistance that makes it so popular.
Euro Cut In relation to how a spear has been machined in to shape to accommodate for a euro trigger or hand piece.
Floatline A piece of thin rope that runs from the speargun to the float. The floating properties of the line keeps it away from the reef to avoid it tangling.
Flopper There to stop the fish from coming away from the spear tip. In some cases the spear might have two floppers.
Gun Bungie A typical gun bungie is only about a metre long and is often linked between the gun and the floatline.
Line release This is the small hook either on the side of the gun or underneath. Which releases the shooting line when the gun is shot.
Loading Pad A small triangle of neoprene or some other kind of synthetic material that is positioned at chest height to protect the diver from the gun butt when loading the gun.
Low Volume This is most commonly refers to dive masks in relation to the amount of air volume they displace when used.
Notch The part of the spear where the bridle hooks into. There are different types. The most common ones are euro which is most often designed for articulated bridles, South African which have a very smooth curve and are often used with dyneema bridles, shark fin which are quite common on larger spears in the likes of blue water guns(or game fish guns)
Open cell Most spearfishing wetsuits are open cell which means on the inside of the suit there is no lining. This makes the suit very flexible but the main trade off is some form of lubricant must be used to don the suit.
Open heel A fin that has a strap around the heel.
Open muzzle Different from an ordinary euro muzzle in that the the gun line holds the spear in place. In most cases open muzzles use rap around rubber slings.
Plat A float which can transport fish whilst being towed by the diver.
Pole Spear A lot like a Hawaiian sling, Articles: Pole Spear
Rail gun Often seen on South African aluminum guns. Basically a track for the spear to slide along in order to keep the gun more accurate.
Rap Around (Rubber Slings) Which pass through the muzzle as one continuous sling
Reel This is normally mounted just infront of the trigger as an alternative to a floatline.
Scupper A small "ducks bill" in the wetsuit to urinate from in order to minimize the amount of urine in the suit.
Shallow water blackout Normally the result of either staying down to long or incorrect breathing pattern before the decent. As a result the diver is depleted of oxygen before breaking the surface on the accent.
Shark Clip Although more commonly used in the long line tuna industry these are ideal method of connecting the speargun to the floatline.
Shark fin (in relation to a spear)
Slip tip The tip of the spear actually slips off the spear but remains connected by a stainless steel cable.
Smooth skin A wetsuit that is smooth on the outside. Less chill factor in the wind & more flexible but because it's exposed neoprene they are less durable. Example
Snooping In New Zealand this term is mostly used when we a looking for Snapper in a stealth manner. Carefully peering over the rocks whilst avoiding any arousal by the fish. Article: Hunting Snapper
Stepping The spearguide may be lower or higher than the trigger. Or the muzzle might be lower or higher than the guide.
Weed Edge/Weed Line Where the sand meets the beginning of the reef.
Muzzle where the speargun rubber is mounted. Also see open muzzles.
Muzzle Bungie Short piece of tubular rubber between the muzzle and the guns shooting line.
