Omer XXV Speargun + Other Fast tracking guns?

Thread Status: Hello , There was no answer in this thread for more than 60 days.
It can take a long time to get an up-to-date response or contact with relevant users.
Hey Corrie,

Stop boasting - just now the whole of DeeperBlue will be diving on the banks:t

One point I agrree 100% with is that there is a nonsensical obsession with 'more power'! Why? I have driven a 7mm spear right through (in the head out the tail) an 8 kg black mussel cracker - this with bog standard omer energy rubbers fitted on my 1m gun. Not over powered or anything - just standard. In SA you will not find too many national level divers diving with double rubbers - why? - because the are not necessary. Just think, SA, the land of big fish and most top divers do not use double rubbers.....'nuff said!!!

I figure with companies like OMER there research and testing budget must be large enough to make my testing and fiddling with rubbers a waste of time!

however with at least 3-4 months out the water due to viz and cold each year we can't help but fiddle with things that aren't broken ! Thats why I usually put my mind to something constructive. This year its a camera mount and if time will start (and finish!) my night diving platform.... oh yes and there is the bait fish style rash vest to make.

Talking of rubbers & fast tracking guns, I just noticed that the DeeperBlue Shopping line [above] sells Dessault gear (see "H. dessault"-link on side its sidebar). And they have the legendary Dessault rubbers (bulk-style band & made-up rubbers) and the Gloworm/Podge approved Dessault Quattro Carbone (& classic). I'm planning to treat myself to some 16mm Dessault bands next time (16mm a good size for Dessault Spaghetti?). Probably bulk rubber. BTW Are the Dessault screw-in rubbers thread compatible with the Omer XXV bridge & wishbone?

Is there any advantage to the two rigging options below?

of course!

in the second one the spear does not wobble around, neither in current nor if you shoot at a funny angle (caves etc)

100% recommend #2

OH, and the clear sighting down the spear too!

cheers! , kinda feel an idiot now reading page 10 - 11. Was being lazy. I have re-rigged it as shown, and now realise the extra hassle that plastic bridge has been when loading.

I left mine as in picture 1, simply because that's how it came and because that configuration is most like my previous gun (RA90) - to reduce changeover differences. Even so, I found it to be quite different. I plan to try the open muzzle configuration in the future, I think it might simplify loading, not for the 75 so much but more for the 90. Try it and let us know what think! (OMD how did they compare for you?)

After one season rigged one way and one the other I conclude that open muzzle version 2 is a pain in the ass to reload. Personally i found the closed muzzle much more practical but if you are not making many shots then the difference of a few minutes per dive isn't much although i found it frustrating at times. It does clear the line of site with open muzzle but the plastic bridge on the XXV is very small anyway. With open muzzle I was using a loop band but I found this off putting when aiming so have gone back to the set up like Pav with screw in bands and the little wire adaptor thingy. This means there is little difference in the line of sight whether open or closed muzzle.

In conclusion I have settled on the screw in bands and closed bridge as in pic on left when using the XXV but this is really what suits me with that particular gun.

I would like to try open muzzle with a hammerhead muzzle and loop band so that the bands start under the muzzle but go over a "pin" to end up parallel to the shaft. Not on the XXV though as the advantage of that gun is the super slim barrel and muzzle but maybe I'll mod another gun if I get a spare moment.

the loading is an issue because, of course, you still have to pass the spear under the wishbone.

in most of my dive sessions I only shoot 2 or 3 times, maybe up to 6 on a crazy day, and I have completely mastered the reload to the point the whole thing takes less than a minute, including playing around and tensing the reel.

but, each to his own. I am convinced that the extra accuracy makes for less shots. Imagine shooting in a cross current, even on a guided gun (rail) with the tip out of the guide, the shot will go a mile off. Then there is the issue of the rigging (line and crimps) passing through the muzzle without a tug or pull deviating the spear.

sounds like an open/closed muzzle debate! just my opinions!

I'm struggling to follow some of the posts in this thread as I am unsure of some terminology.

These terms ;

Open Muzzle
Closed Muzzle

and

What term is used to describe the style where 2 rubbers are used?
What term is used to describe when a single rubber is used that passes through the large hole?

I'm kinda working it out but clarification would make it easier for me as I am now reading the pages of this thread with renewed interest.
 
open, right picture
closed, left picture (with a bridge or hole through which the spear goes)
2 rubbers often called "screw in rubbers" advantage in line with spear, dissadv. a bit more costly
1 rubber, out off line with spear, unless some "hammerhead" riser/diverter used, cheaper, called "circular" bands etc. Need to level them up a little sometimes as they slide round.

there is a lot to learn on an apparently easy subject! keep reading
 
Images per Azapa's response above. Closed means the clear plastic bridge is in place on the muzzle; open means that it has been removed.

Per Azapa's response, screw-in rubbers for the former. I usually call the latter "bulk rubber" - although for the XXV "circular rubber" is more accurate as the XXV Gold comes with an Omer band that accepts screw-on wishbones. My XXV isn't the Gold, so didn't come with the extra circular band, so I will likely use bulk rubber and a (soft) dyneema wishbone for that configuration.

As you questions suggest, the rubber configuration and the muzzle configurations are orthoganol, that is, independent of each other - you can mix & match, a key feature of the XXV muzzle.

if anybody has any reviews on cayman carbon by omer it would be aprriciated

Re. early reports of the Cayman were positive but I have not seen any detailed reviews on it (try searching this site though - I might have missed some). It appears to be of more traditional dimensions that the XXV and with broader applicability (more suitable for bigger fish). The constant tension-trigger appears to be a significant technical advance. The handle design is supposed to be v. comfortable and probably well suited for the more normal barrel-diameters used (28mm v. 25mm). I'd happily buy a Cayman if I need another speargun.

One further point, re. circular rubbers/bulk rubbers - the traditional railgun muzzles (used by Rob Allen, Rabitech, etc.) align the bulk rubber bands with the spear as well as any screw-in band designs.

The HF2, is very easy to move for side to side as well as up and down. In the water is a very pleasant gun to have. In Fact is the most pleasant gun I have in the water. The only issue is the noise, very loud, but it is a very nice gun to shoot mullets. I have the 100 HF2LE, I will probably get a 90.

The trigger system is the ome signature cayman, very light, the HF2 muzzle is OK the same as the XXV.

The gun is very acurate, I've replace the original band with on circular one and rope wishbone. I am also using the one 6.75 140 cm shaft, fantastic shaft, the rig works great, I wish all my shafts have that ring.

Thanks! Ive had been worried because my old gun was a sea hornet lazer and i wanted something good!

Welcome to DB ifishanyweather, the guys/gals or here are always happy to help

Im sure your new gun will be a million times better than the Sea hornet lazer

what size gun did you go for? Does your Dad spear?
 
thanks and no he dosnt spear but hes starting in summer with my sea hornet lazer and polespear i picked a 75 for good tracking in rocky areas
 
I found them a bit soft so stuck with the 3000's which imho are great fins with plenty of power.

Im not sure but I think Anthony ( Venture storts) said something about the 3000's been fazed out next year which is a bummer
 
Hello all Omer xxv owners! I bought one a year back now and am trying to fit a reel to it but realise that I have lost the metal line guide from the muzzle... anyone have any idea where I might be able to get one from?
Cheers
Chris
