Their solution was to use an small canister of compressed CO2 with a syringe needle that simply injected the gas into the shark body. The solution was the shark darts and it was developed by scuba equipment company name Farallon Industries. The Navy SEALs needed a weapon to repel shark attack quietly without cause the target bleeding, which only attract more sharks to the site. During the 1960's, it was the Navy SEALs job to secure and retrieve the astronauts from their splashdown capsules and the weapon needed also for the SEALs regular low profile operations. In the mid 1960's, the US Navy had a need for a new weapon for their divers.

So, if it so good why isn't it the leading bang-stick in the market? Although the US Navy did test it and with good results, only a small number been purchase and the civilian market wasn't (and still isn't) large enough to justify manufacturing of such a custom-made rounds.

Angle of approach – the front side of the cartridge has concentric circular ridges, when contacting with target at a shallow angle those ridges prevents the bangstick from slipping out and instead provides good traction for the cartridge to slip into the firing pin.

Safety – the diver don't hangout with a loaded stick until he/she face a danger.

Loading speed - don't need to disassemble the powerhead, remove spent case, place new one & assemble just place new round in place.

Lethality – according to some reports the Seaway could cut a shark into two halves!.

the Seaway is superior to civilian bang stick in any way: After the initial blast there is a short period of low pressure in the front area of the spent cartridge and water flow thru the six holes to push the spent cartridge out of the powerhead and it ready to be loaded with a fresh cartridge again. 30-30 diaphragm is blasted and the target receives its deadly dose of shockwave. When contacting the target the cartridge slips in and ignited. The cartridge structure prevents it to slide all the way to the firing fin and instead it stacks 1/2 inch sticking out of the tube. Around the firing fin there are six radial holes.The Seaway is muzzle loaded, the diver strip a cartridge from 6 rounds bandolier on the diver's belt and place it into the muzzle with the.
