difference between 2 HPA tanks

I was looking into getting a new tank, something smaller then what I have now. I was looking at getting a 45k tank until I saw on pbgear.com a 70k tank which looked smaller and stubbier then the 45 tank. What I wanted to know is what is the difference in size and weight between the 70/45 tank and the 45/45 tank?

70/45 tank

45/45 tank]

Ok...anyone else?????

No matter what it looks like the 45/45 is smaller.  But you wont get as many shots.  I would suggest a 68/45.  Thats what im getting.  Just small enough for me.  Good amt of shots.

just get a 68/3000 if the 68/45 is to big

Picture size.  If you were able to see both in person, the difference would be huge.

Seems like someone fergot that working out wit wieghts helps in holding such tanks....dude , if you start working out wit yer arms, you wouldnt be askin what size tank would be easier to carry...seriously, people need to workout, lift some weights, it'll help anyone in the long run and if you dont think so....ask the "pro's" on what they do to keep in shape.

Size really doesnt matter, the tanks yer talkin bout is like carrying a 2lbs weight, theyre not that heavy and if size is yer major concern, the smallest is a 45/45 and you know you cant get any smaller than that unless yer gonna use a 9oz co2 tank...but, like you said, you wanna tuck yer marker into you....I know yer gonna hate what Im gonna say...but, Imma say it anyway, use a "remote line" and the tank can either be on yer belt or on the back of a harness oooooor you can reverse the tank adpater to where you can screw the tank in the front.

LOL your right I don't like the idea..sorry. I had a remote before on my 20oz co2 tank for my Tippy and I didn't really like it. If the smallest HPA tank your going to get is 45k then thats what I'm getting.

Ok well think of it this way. The first numer in this case the 70 refers to the number of cubic inches of fluid it could hold. So obviously tyhe 70 is bigger. The 4500 at the end refers to how much pressure the tank can hold. So a 70/4500 tank and a 45/4500 tank hold the same pressure but are different sizes. This means the 70 is bigger, holds more and is a bit heavier. If your front you will probably want to go with the 45 so you can get tighter in yoru bunker but if you play back you will want the extra shots from the 70. Its also alot of preference. Because some people dont like the smaller tank. If possible try seeing if anyone at your local field has a 70 or a 45 and see if you like it.

the 70 is bigger, but it is not as long as the 45/45 or tthe 68/45..if you want a tank taht is not long get the 70/45
