Jeg overvejer at skifte min elastik ud på min Cayman ET 85 da den er ved at få lidt revner. Endvidere synes jeg at elastikken på min nye Cressi Geronimo Elite 85 er ekstremt svær at lade. Det bliver ikke til mere end første hak, så jeg kunne godt tænke mig en der var lettere at lade.
Jeg har læst Lambertos indlæg om “progressive” og “reactive” elastikker, men jeg er ikke helt sikker på hvad forskellen er.
Kan nogen anbefale nogle elastikker til ovenstående formål? Nogle der er nemme (alt med måde) og lade, men fortsat med smæk på.

Hej Jesper… Jeg vil råde dig til at bruge det nye Divecenter… Der er umiddelbart meget få mennesker i vores land, der har mere forstand på harpun elastikker end Lamberto.. Det har jeg gjort og jeg bliver rigget til efter alle kunstens regler på LL cup…
Jeg kan jo give dig en tilbagemelding efter weekenden når de nye elastikker forhåbentligt er blevet testet max 🙂 ..
Ses.

Jeg har skrevet til dem via deres website, men jeg har ingen reaktion fået på min henvendelse. Så jeg ville lige tage en føler på emnet herinde i stedet for. Og noget tyder på du har ret, for der er jo ingen andre der har svaret.
Kan du løfte sløret for dit setup?
Hi,
We have changed server two weeks ago and i’ve got the idea to use a Debian root server….. basically you should start from scratch from command line…. the mail server has been off line for several days while i tried to set it up during endless and sleepless nights :sick:
Now it works :woohoo: and actually i will be happy if someone can try to send me an email to [email protected] so i can try to reply and see if it goes through the antispam filters… gmail fo one is a nightmare.
Back to rubbers: the Cayman ET is a gun that can receive quite a lot of power because the rail. You can use only spears Omer America or similar with sharkfins but they are not easy to find in Europe as everybody now make them with pins instead.
The standard rubber Omer 18mm lack a bit of “juice” with the spear 6,5mm but it may do pretty well with a 6,25-6,2 mm.
If you want to keep the 6,5mm spears, that are easier to find on the market, i suggest two rubbers 14mm @ 340% for an easy and precise shot or two rubbers 16mm for a more powerful shot, still with good precision but with more recoil. Someone like Topper can handle the double 16mm without problems but it all depend how firm you can keep you arm when shooting. Double 18mm is a no-go as it would be too much for a 6,5mm spear.In LL i will have with me some meter of Sigalsub Reactive Brown in 16mm and 17,5mm, along with a lot of dyneema and a target plate…. Topper will tell you how it goes 😉
We should remember that the commercial guns are designed to be used by average spearos and in all-round situations: one single 17,5mm Sigal Reactive will probably improve the gun in 98% of the situation but if you are looking for mullets at 3+ meter distance then it will need a bit more than that.
And by the way, we seriously think to build the first and only “Spearguns Testing Tank” in Scandinavia… a 7m long “aquarium” where you can shoot your gun in the water through a rubber glove in the tank bottom (with glass of course)… testing different spears or rubber sets will be much easier then and also will be possible to measure the ballistic performances in real time. I hope it can be ready before Christmas!
Cheers!… and please send an email!

Hi Lamberto
Im planning to change the rubberbands on my ET75er, i use 2 bands, what lengths do i need to use (don’t get the % stuff, and how to measure it :o)
So:
length of 2x 16mm (or 14mm) rubberbands (Rubber Reactive Brown) ?
Materials to make the wishbones (do i need the metal pearls to insert in the bands, or is a well done knot ok (as on divecenter.dk 😆
What tool to use to insert in rubberbandI could have wrote to you on divecenter, but think many us like to know how to ?
Thanks in advance

MichaelHi,
To rig an all-round gun between 75 to 100-105cm, the best configuration is 2x16mm pairs of rubbers (or two circular rubbers) and a 6,5mm spear.
Variation in plus-minus of the spear lenght/caliber and relative rubbers will increase speed and reduce range or increase range and decrease speed: it all depends about your preferences and the kind of fish you will hunt. For example a 7,5mm spear used to catch dentex in the med is too slow and the fish will not be there when it arrive, while a 6,25 will be burning fast… the opposite if you are going to pierce a 50cm wide tuna where a 6,25 will just tickle it: in that case you will need a thick and heavy spear with a lot of rubber pushing it at the limit of it’s bending force.
Wishbone: A wishbone in metal is around 20g and one 6,5x115cm spear is ~300g. This mean that 6,25% of the rubbers energy will be used to move forward the wishbone alone… this if we don’t consider the weight of the rubber it’s self. It is not much but for the “speargun nerds” like me it make difference 🙂
The small perls in brass or plastic are making the full process easier but they are doing the same job of a “diamond knot” that is just lighter. The dyneema wishbone on divecenter.dk is handmade after the gun’s measures and is the lightest you can get: of course is better and more fun to learn the knots necessary and do it yourself :cheer: . A nice video about that knot is http://youtu.be/3wphtnYYhT0 and toghether with this http://youtu.be/jqR4eqS75E8 you have your wishbone in Dyneema! (the thing he use in the video to lubricate is regular handsoap… don’t use oils, WD40 or similar stuff!!)Ciao!
