Working on my research for my 1st PCP rifle...and Hammerli Pneuma Elite 10 .22 seems quite promising to me.

So I have a goal to save my money for...

I think I will go for the scuba tank (used) path to feed/fill this rifle, and what I need to concern before I paid for them...

do I need any kind of connector for the rifle and the scuba tank?

Isn't it there is a life time for the scuba tank just as propane tank that after 10 years the pro-shop won't refill the tank for you any more?

Do I need to buy a hand pump for exercise...I mean, back up? and which brand and where I can have one?

Gee, what else I missed? please educate me!

Thank you in advance...
