● Demkina gibljiva glava drzi puscico ves cas tesno v vodilu, ne glede na polozaj puske (postrani alinavzdol). Gibljivi del se med strelom dvigne in tako sprosti puscico, istocasno pa ustvari toliko prostora,da prakticno ni mogoce zapletanje vrvice. Glavo je mogoce prilagoditi uporabi puscic ∅6 do ∅7mm.Luknja za vrvico je ojacana z medeninastim vlozkom, kar preprecuje obrabo vrvice pri intenzivniobremenitvi.

● Demka’s articulated muzzle holds the spear firmly in place regardless of the position of thespeargun (sideways or upside-down). The moving part is lifted during the launch, releasingthe spear and creating enough space for the line of the spear to pass with virtually nodanger of entanglement. It has an adjustable socket for spears from ∅6 to ∅7mm. The holefor the reel line is reinforced with a bronze tube to avoid wear during intense movements.

Demka Spearguns was first to manufacture, in 1987, Tahitianspears using stainless steel by SANDVIK with a tensile strength

of more than1800¡/mm2.

All spears by Demka Spearguns have been processed in the area of the cord-hole using the sandblastinc tecchnique, resulting in a

dramatic decrease of cord wear.

Demka je v letu 1987 prva pricela izdelovati tahiti puscice iznerjavecega jekla SANDVIK s trdnostjo

vec kot 1800¡/mm2.

Vse Demka Tahiti puscice imajo luknje za vrvico obdelane speskanjem, kar izredno zmanjsuje

obrabo in poskodbe vrvice

5. KOMPATIBILNA VISINA OBLIKOVANEGA ZADNJEGA DELA PUSCICE

5. Compatible height of interlaced end of spear

● Kompatibilnost puscice s sprozilnim mehanizmom je odvisna od visine in tolerance oblikovanegazadnjega dela puscice. Potrebna je velika previdnost, saj se lahko nekompatibilna puscica nenadoma sprozi brez pritiskana sprozilec, kar je lahko smrtno nevarno.

● Prava vviissiinnaa iinn ttoolleerraannccee (v mm) oblikovanega zadnjega dela puscice za uporabo s sprozilnimmehanizmom sta navedena.

● The compatibility of a spear with the trigger mechanism of the handle of a speargun depends onthe height and tolerances of its interlaced end. Caution is needed because an incompatible spearcan be launched suddenly without pressing the trigger thus putting human lives in danger.

● The appropriate height and tolerances (in mm) of the interlaced end of a spear, in order forit to be compatible with the trigger mechanism of the speargun, are stated.

6. PLOVNOST PUSKE

6. Speargun buoyancy

● Navedeno je, ce ima puska brez puscice negativno ali pozitivno plovnost.

● It is stated whether the speargun, without the spear, has positive or negative buoyancy.

7. OBCUTLJIVOST SPROZILCA

7. Trigger sensitivity

● Obcutljivost sprozilca je definirana s silo, s katero je potrebno stisniti sprozilec. Za obcutljivejsi sprozilec je potrebna manjsa sila, kar se odraza pri preciznosti strela.

● Obcutljivost sprozilca je podana v obliki ddiiaaggrraammaa, ki prikazuje silo potrebno za pritisk na sprozilecv odvisnosti od sile napetih gum na puscici.

Iz primera v diagramu je razvidno, da pri uporabi gum z 800N sile, sprozilec 1 potrebuje 14N zasprozenje, medtem ko potrebuje sprozilec 22 samo 9N. To pomeni, da je sprozilec 22 obcutljivejsi od sprozilca 1.

● Razpon vrednosti (.¯. ±10%) pridobljenih s testiranjem primernega stevila vzorcev je tudinaveden (nivo zanesljivosti: 99%).

● Trigger sensitivity is defined as the level of difficulty with which the trigger of a speargun can be pulled.Pulling a sensitive trigger requires a small force thus contributing to the accuracy of the shot.

● Trigger sensitivity is given in the form of a diagram showing the force necessary to pull thetrigger in relation to the total force applied by the rubber-slings on the spear. In the example ofthe adjacent diagram it can be seen that when rubber-slings of a total force of 800N are used,trigger 1 needs 14N in order to be pulled while trigger 2 needs only 9N. Therefore, trigger 2 ismore sensitive than trigger 11.

● The range of values (.¯. ±10%) deriving from tests on a sufficient number of samples is alsoreported (level of confidence: 99%).

8. MAKSIMALNA OBREMENITEV SPROZILNEGA MEHANIZMA

8. Endurance limit of trigger mechanism

● Maksimalna obremenitev sprozilnega mehanizma doloca maksimalno silo, ki jo lahko povzrocajonapete gume na sprozilni mehanizem, da je uporaba puske se varna. Ce je ta obremenitev presezena,obstaja nevarnost okvare sprozilnega mehanizma ali rocaja z nepredvidljivimi posledicami.

● Maksimalna obremenitev sspprroozziillnneeggaa mmeehhaanniizzmmaa je podana v Newton ih. (N)

● Z ozirom na pomembnost tega podatka za varnost uporabnika, je potrebno upostevati varnostnifaktor. Zato je maksimalna obremenitev sprozilnega mehanizma definirana kot 50% od najnizjeizmerjene vrednosti sile, ki je povzrocila poskodbo sprozilnega mehanizma med testiranjemprimernega stevila vzorcev.

● The endurance limit of a trigger mechanism determines the maximum rubber-sling force that canbe safely used on the speargun. If this limit is exceeded then there is danger of failure of thetrigger mechanism or the handle with unpredictable consequences.

● The endurance limit of the trigger mechanism is given in Newton (N) units.

9. PRECIZNOST STRELA

9. Shot precision

● Preciznost strela podvodne puske se odraza v zmoznosti puske da s ponovljenimi streli posljepuscico v isto tocko

● V skladu z Demkinimi Standardi je preciznost strela podvodne puske opisana z rraazzpprrssiittvviijjoo ppeettiihh((55)) ssttrreelloovv v tarco namesceno na doloceni razdalji od vrha puscice.

● The precision of a speargun reflects its ability to send the spear at the same spot in repeated shots.

● According to Demka Standards, the precision of a speargun is described by the dispersion of

five (5) shots at a target positioned at a given distance from the tip of the spear

10. HITROST STRELA

10. Shot-velocity

● Cas (od trenutka ko je pritisnjen sprozilec) potreben da puscica prepotuje razne razdalje, definirahitrost strela podvodne puske. Vecja je hitrost strela, vecja je moznost, da puscica doseze ribo,preden se le ta premakne

● Hitrost strela podvodne puske je razvidna iz diagrama ppoott –– ccaass. Visja kot je krivulja, vecja jehitrost strela. Iz primera v diagramu je razvidno, da prepotuje puscica puske 1 3 metre v 120millisekundah. V istem casu prepotuje puscica puske 22 manj kot 2.5 metra. To pomeni, da imapuska 1 vecjo hitrost strela na tej razdalji.

● The time (from the moment the trigger is pulled) necessary for the spear to cover variousdistances defines a speargun’s shot-velocity. The greater the shot-velocity of a speargun is, themore chances the spear has to reach the fish before it moves out from its course.

● The shot-velocity of a speargun is depicted on the displacement-time diagram. The "higher"the curve is, the faster the shot of the speargun. In the example of the adjacent diagram, the spearof speargun 1 covers 3 meters in120 millisecond. In the same period of time, the spear ofspeargun 2 covers less than 2.5 meters. Therefore, speargun 1 gives faster shots at this distance.


11. DOMET

11. Range

● Sposobnost puscice za preboj tarce namescene na razlicnih oddaljenostih definira dometpodvodne puske.

● Domet podvodne puske je razviden iz diagrama eenneerrggiijjaa--ppoott, ki prikazuje kineticno energijo puscice(v Joulih) na vsaki tocki njene poti. Vecja je kineticna energija puscice na doloceni razdalji, vecja je

moznost da bo puscica prebila ribo, ki se nahaja na tej razdalji. Iz diagrama je razvidno, da imapuscica puske 22 na razdalji priblizno 3 metrih energijo 40 J. Puscica puske 1 ima enako energijo namanj kot 2 metrih. To pomeni, da lahko puska 22 prebije isto ribo na vecji razdalji kot puska 1. Z drugimi besedami to pomeni, da ima vecji domet.


● The ability of the spear to penetrate targets located at various distances from it, defines the rangeof the speargun.

● The range of a speargun is depicted on the energy-displacement diagram, which shows thekinetic energy of the spear (in Joule) at each point on its course. The greater the kinetic energy of aspear is at a given distance, the greater the chances to penetrate a fish located there. In the exampleof the adjacent diagram, the energy of the spear of speargun 1 is 40 J at approximately 3 meters. Thespear of speargun 2 has the same energy at less than 2 meters. Therefore, speargun 1 can penetratethe same fish at a greater distance than speargun 2. In other words, it has a greater range.

● The maximum elastic bending moment of a spear is the maximum moment to which it can besubjected without suffering significant permanent deformation. In other words, it is a measure ofthe spear’s ability to maintain its straightness after being subjected to repeated stresses that tendto bend it.

● Two values of maximum elastic bending moment (in Nm: Newton x meter) must be given foreach spear. The first value should correspond to a part of the spear that has not been subjectedto machining. The second value should correspond to the area of the slot or the shark-fin.

● The range of values (.¯. ± 1 Nm) deriving from tests on a sufficient number of samples is alsoreported (level of confidence: 99%).

10. TRDOTA

● Trdota puscice je merjenje njene sposobnosti da ostane ostra po veckratnih udarcih v trdopovrsino. Tako lahko predvidevamo, da bo vrh trse puscice oster dalj casa kot enak vrh mehkejse puscice.Ta specifikacija velja samo za Tahiti puscice.

● Trdota puscice je podana v Rockwell C skali.


● The hardness of a spear is a measure of its ability to remain sharp after repeatedly hitting hardsurfaces. We may predict, in other words, that the tip of a high-hardness spear will last longerthan the identical tip of a low-hardness spear. This specification refers to Tahitian spears only.

● The hardness of a spear is given in the Rockwell C scale.

● Statisticno maksimalna obremenitev krilca odgovarja maksimalnemu upogibnemu momentu,katerega delovanje ni povzrocilo zloma krilca 99% testiranih vzorcev.

● Barb strength is defined as the bending moment necessary for its destruction. It is, in other words,a measure of the barb’s ability to withstand bending forces, like those developed during the abruptmovements of the speared fish, without collapsing. This specification refers to Tahitian spears only.

● Barb strength is given in Nm (Newton x meter).

● Statistically, the strength of a barb corresponds to the maximum bending moment, the applicationof which does not cause failure to 99% of the tested samples.

12. STANDARDNA ENERGIJA PREBOJA

12. Standard punching energy

● Sposobnost puscice za preboj ribe je predvsem odvisna od njene kineticne energije. A tudi oblikavrha in krilca, pa tudi premer puscice, lahko preboj olajsa ali otezi. Standardna energija preboja je meritev vpliva vseh teh morfoloskih lastnosti na sposobnostpreboja puscice. Ta specifikacija velja samo za Tahiti puscice.

● SSttaannddaarrddnnaa eenneerrggiijjaa pprreebboojjaa je podana v Joulih (J).

Odgovarja energiji potrebni da prvih 20cm puscice (vkljucno z vrhom in krilcem) prebijestandardiziran vzorec. Vecja je standardna energija preboja puscice, tezje bo le ta prebila ribo.


● The ability of a spear to penetrate a fish depends primarily on its kinetic energy. However, the shapeof the nose and the barb, as well as the diameter of the shaft, can make the penetration easier orharder. Standard punching energy is a measure of the influence of these morphological features to

the penetrating ability of a spear. This specification refers to Tahitian spears only.

● Standard punching energy is given in Joule (J). It corresponds to the energy consumed for thepenetration of the first 20cm of the spear (including essentially the nose and the barb) to penetratea standardized specimen. The greater the standard punching energy of a spear is, the harder it isfor it to penetrate a fish.

● The range of values (.¯. ± 1 J) deriving from tests on a sufficient number of samples is alsoreported (level of confidence: 99%).

4. OPTIMALNI RAZTEZEK

4. Rubber-sling optimum elongation

● Za vsak tip gume obstaja raztezek, katerega prekoracitev povzroci ostro povecanje sile napenjanja,ob minimalni pridobitvi (ali celo izgubi) hitrosti strela, istocasno pa se zmanjsa zivljenjska dobagume. Zaradi tega mora biti raztezek, s katerim ima po proizvajalcevih podatkih guma optimalnelastnosti, vedno naveden za vsako gumo.

● OOppttiimmaallnnii rraazztteezzeekk je podan kot procent zacetne dolzine (npr. 180-200%). To odgovarjamaksimalnemu raztezku, pri katerem, ce je raztegnjena 30 minut, guma obdrzi 95% energije, ki sesprosti ob pocasnem povratku gume na prvotno dolzino.

● For each type of rubber-sling there is an elongation which, if exceeded, will lead to a sharp increaseof the stretching force with minimal gain (or even loss) in the shot-velocity, as well as to areduction of the rubber’s life-time. Therefore, the elongation at which, according to themanufacturer, the rubber-sling has optimum behavior must be stated.

● Optimum elongation is given as a percentage of the initial length (e.g. 180-200%). It correspondsto the maximum elongation at which, if the rubber-sling remains stretched for 30 minutes, it willmaintain 95% of the energy released during its slow release.

6. STANDARDNA ODDAJA ENERGIJE (30cm)

6. Rubber-sling standard energy output (30cm)

● Hitrost puscice med strelom je odvisna od njene teze in energije prenesene nanjo s strani gummed strelom. Primerjalno merjenje teh karakteristik razlicnih tipov gum je v bistvu merjenje energije, ki jo gumesprostijo pod standardnimi pogoji testiranja.

● SSttaannddaarrddnnaa ooddddaajjaa eenneerrggiijjee gume je podana v Joulih (J) pri 200% raztezku. Odgovarja energiji, ki jo sprosti par gum dolzine 30cm (ali 60cm dolga cirkularna guma) zustreznim zatikom, na ∅7mm puscico brez krilca, teze 350g, med strelom iz puske dolzine 100cmz vodilom. Puska je trdno pritrjena v posebnem stojalu 0.5m pod vodno povrsino.


● The velocity of the spear of a speargun during a shot depends on its weight and the energy transferredto it from the rubber-sling during the launch. A comparative measure of this characteristic of differenttypes of rubber-slings is the energy they release in standard conditions of testing.
