Hi all,
Im jast wanting to get a bit of advice from some people with a bit more experience than i have about a gun i just bought. I ordered an omer cayman 2000 thinking it was a rail gun, when i got the gun i was pretty surprised to see that not only was it not a railgun but there is no spear guide what so ever along the barrel, just the muzzle and the initial spear placement in the mech to keep it straight (and the bands i guess). So the dilemma i have is that i can pay and extra $70 to get a cayman oz edition which is equipped with a rail which ide be happy to pay, but ide also have to pay an extra $70 to send the cayman 2000 back to the shop (so $140 for the upgrade) or i can just use the Cayman 2000. Im pretty new to spear fishing so maybe no spearguide down the barrel is faily normal im not sure (it seemed weird to me). So the question i am asking i suppose is, will the addition of a rail down the barrel make a lot of difference hence being worth the extar $140 (the oz also comes with an open muzzle and a 7mm spear in comparison to a 6.5mm on the cayman 2000) or would a relative newbie like me not even know the difference.
p.s. i know i should have probably bought my gun from a dive shop to reduce there problems but the closest one is 1.5 hour drive
 
Okay so after going through this section on the forum it seems as though many people think on a shorter gun as i have bought (100cm) a rail does not really make much difference, sorry for wasting peoples time on a subject well talked about already. If Anyone has anything to offer on this subject though anyway i would still love to hear it. Cheers
 
Hello Speargrub and welcome on DB

Before going in details with the answer the main criteria for choosing a speargun is the type of the fish you catching(Small/ big/ huge) and the visibility of the water (It is not logical to get 120 cm gun with visibility of 1 or 2 meters!!!) and the recommended brands for smaller range gun is different than big ones (For smaller range 60-90 guns i prefer cressi comanche(No rail) and for bigger range 100 + rob allen(Rail Gun) as aluminium guns)

I have cressi sub comanche which is as you are mentioning without rail and many guns are dsigned as your gun where they are accurate and great guns check this link explains eveything about the speargun Speargun)... as for open muzzle it is prefered to me because i can use sharkfin shafts that i can connect easily to steel line and it will not stuck in the muzzle when you shoot the fish...

As a conclusion you can keep your gun and it will be working well but you can upgrade if you have enough money for better brands (Prefered to me Rob Allen)

All best
 
Cheers for the info, i am only really spearing smaller fish off the bank/reefs. The biggest fish i have pulled out of the water so far was a 3kg mangrove jack but more often the fish around where i dive are not much bigger than 40cm. Visibility is really variable i can only really dive whe the surf is real low and visibility is usually only between 3 - 6 metres due to swell kicking up sand (im not really sure what would be classsed as bad visibility i dont consider it particularly good though). sounds like maybe what i have is an ok option though
 
A 100 sound like a good choice to be, a 90 would of been easier to load but the 100 will give you a bit extra on clear days.

Cheers for the feed back guys. I decided to keep the Cayman, took it out for a dive and its great, feels almost weightless uderwater and really comfortable to handle and nicely balanced, although my old gun was a bit of a junk bucket so i dont have much to compare it to. Got a couple of fish on the first dive woo hoo.
 
yep i did take a photo hopefully this attachment worked. The chopping bloc is 47cm long for reference. I hadnt eaten these before but been told they were ok, they have a bit of a weedy flavour so skinned and fileted them and chucked em in a big curry and they werent to bad.

the gun you got spargrub is most likely Omer Excalibur 2000, which has a simple shaft guide secured to the barrel with a plastic screw, very nice, simple and relaiable gun. Omer Cayman is indeed a railgun, also very good. Cayman OZ were made sp. for Australia by Omer and as far as I know the (plastic) rails were added to basic barrels. If your gun has a Cayman logo and doesn't have an integrated rail along the barrel, then it might be of the 1st. batch of Cayman OZ which were supplied without (plastic) rails.
