i was wondering if a single 18mm band to the 1st notch was powerfull enough. i want to add another band but i heard that the t20s are most accurate when stock so im not sure what type and how stong of a band i should add.
 
Hey there,

Don't worry about the accuracy, you'll get used to it. Hold the gun steady when you shoot. It will actually be more accurate farther away thanks to the extra band since the shaft will drop slower. I would use two 16's though, you might find 2 18mm's overkill...

Which T20 you use with double 16mm? which shaft? and how is the accuracy? how much recoil?

Accurate enough for 50kg fish or accurate enough for 0.5 kg fish?

sorry with too much question, i am thinking to buy new double bands speargun
 
Hey Murat what's up.

Accurate enough at 15ft(4-5m) away on a 110 to shoot a 10-50kg fish. for the .5Kg fish it's better to stick to one single, because at 3-4 meters which is probably about as far as you shoot one of these smaller fish anyway the pin point accuracy given by the stable gun is important.

This is why I suggested he go to two 16mm's bands that provide more of a gradual, less "hitting" type of punch, they're smoother and have less recoil than the snappier 18's.

ps- I should have told you that on my Master America 130 that I shoot with an 8mm shaft I use three pairs of 16mm rubbers for blue water. When I shoot smaller game with that gun using a 7mm shaft I tone it down to 2 18mm's. But that gun is much heavier than a T-20 carbon or aluminum since it's wood which is why I reccomend 2 16's for those guns.

what about a 18mm band to the 1st notch and a 16mm band to the 2nd you think that will work good? or might it over power then gun?
thanks for the replys

bands should push the shaft with same force for optimum performance there bands should be equal diameter and size if they strech same amount. They also should be same condtion e.g new, old etc..
 
Good point
Do you think the same would apply on a rail gun too? As the spear is held on a track for its entire travel down the gun
 
so what your saying murat is i shouldnt have 2 different size rubbers on my gun? either 16 and 16 or 18 and 18 (both new) but they wont strech the same amount...

Alison it does not matter if there is rail or not you still should have same diameer bands. Imagine if one is pulling the shaft faster than other what is use for other weaker band?

findmeryan,
yes what i meant is you should have same dimaeter bands on your gun. You can calculate the approciate length with 1/4 rule but i am not expert on band sizes of double rubber guns since i don't have any yet. You can also find suitable band length to your needs by trial and error, 1/4 rule is good place to start with and modify both of your bands at same amount.
