Can you give more specs about your roller setup on the 82? Was it one roller plus a kicker band?
Would you recommend 14 mm small id bands @ 360% for a Pathos Sniper roller 95?

I run a pathos 50 with a roller head and it puts any 60cm band gun to shame. Just a mantis roller with 16mm small ID band at %380. 16mm bands will be better on a roller since initial power is critical.
It nearly matches my pathos 82 in power and accuracy.

Thanks. I will give that setup a try once I have worn out these bands.

Re: 130 Rob Allen Rollergun Review

Real nice reply... I was imagining the whole event in my mind , I'm sure shorter rollers are the way to go, unfortunately longer ones are disappointing to say the least, maybe not all of them though. There're some interesting double rollers around, that probably worth a try

In my testing I found that with the roller, I would lose accuracy if I pushed the power up and I settled on a band load that gave me minimal pre-stretch. That thing shot super accurate (3 shots 1 hole at 4 meters) but it lacked power (did not pass the KM penetration test at 5 meters). I also used the best classic setup, which was 2 x 14mm small ID bands at 360% ... same accuracy but much more power (passes the KM penetration test at 5 meters). I also took my Abellan 110 on this trip, and first shot on the reef my shaft got lodged in so hard ... wasted like 30 minutes and 4 dives to pull it out. Decided to go with the roller 82cm setup ... and man I was stoning everything ... I had like 5 or 6 consecutive stone shots. But then I had this long shot on a grouper that was running away and I took a shot that I should not have taken, and was really lucky to land the fish as shaft didn't penetrate fully through the fish. I then switched to the classic 2 x 14mm setup ... and results were even better. I didn't have too much power where my shaft would lodge in the reef, but it was more than enough power to land even some pretty large grouper, plus loading the gun was much quicker. The accuracy I was getting with this 82cm setup was phenomenal ... with the classic 2 banded setup I had more power than I remember having with my old Riffe 120 default factory setup !!! The trip was actually a blast from the past as I have not hunted local grouper in like 20 years. It is pretty incredible how much technology has changed equipment.

So ... rollers certainly are an option, and I will say that the Pathos roller head is probably not one of the good heads (doesn't use bearings) and for sure you will get some performance improvement with a better quality roller. Maybe there are some new roller heads out there that deal with the problem of tail lift with pre-stretch (like the SEATEC), and this would solve the problem of keeping accuracy while pushing power up. Need to try those out. But really, you can't go wrong with the simplicity and power of a classic setup. I will try and put out a video of that 82cm setup in both roller and classic configurations shooting fish ... I was blown away by the performance of both setups and they really confirmed results of my pool testing.

WHERE are you diving that you need a 50cm gun? Is it so dirty that you shoot fish point blank? I cannot picture going diving in such dirty water that I cannot use, at the very least, a 75cm gun!

That's par for the course in norcal. They shoot in holes a lot up there, the only fish they shoot in the water column are rock fish which are kinda dumb. As I understand it a 90cm is around the max size they hunt with.

Yep, that's the truth. My "long" gun for the Mendocino coast is a RA 70. I'm headed there for our annual 10 day family vacation in a couple weeks and will probably use my little Riffe 33" C-0 most if not the whole time.

Ha come to new jersey. You either dive in 3 to 5 ft vis or you dont dive. And your shooting thick fish and need punch. Ha ha.

For those conditions I would get a 90 Cyrano. It has a lot of punch with the size of a 60 cm banded gun overal.

My thoughts exactly. For small guns, pneumatic is the way to go! In my opininion....

I have a 85 salvimar darkside carbon with stc vaccum muzzle. But my new fav is a 3 band 38 midhandle. Way better in poop vis and i can power down and shoot smaller fish in rocks. My 85 airgun will trash the shaft instantly. Even a small roller can power down. My air gun has a power regulator but it wont go from high to low on the fly.

Re: 130 Rob Allen Rollergun Review

After missing a lot of fishes and mauling some more (due to the 130 rollergun shooting low) I decided to change on the boat the configuration and switch the head of my 1000 Ra but it was impossible, th guys of " The diving factory" AKA ROB ALLEN, put the screw of the rollerhead so tight, that is impossible to remove it without the use of a vise or powertools... Another drawback for the roller in that sense...

If it doesn't goes from high to low just by moving the lever, there's something wrong with your gun.

Goes from low to high while loaded. But not high to low loaded. Once its on high you can flick lever all ya want it will still shoot high power.

I agree with Marco. The lever is there exactly to allow you to power down your gun to avoid ruining shafts. If it is not working like that, something has to be wrong. Did you contact de manufacturer and see if you have something to say?
