I recently got a gx portable pcp air compressor and it’s been working great but i’d love to have a small tank to take with me when out in the field. The scuba shop in my area only fills to 3000 psi so that’s not an option so if anyone knows of a small tank I could buy and fill with my compressor it would be greatly appreciated. I’ve been looking at some ninja tanks like this one https://www.ansgear.com/Ninja_68_4500_Tank_SE_Mohave_Adjustable_p/ninjatanklw-68-mhv-adj.htm?gclid=Cj0KCQjw3s_4BRDPARIsAJsyoLNDueeJnH9RhOocIuWHmgBvBFN8OodbZCuoR2bRy-tctrD87qe5UUoaAkgYEALw_wcB and it seems like what i’m after and cheap but any advice would be appreciated. I’m pretty new to the filling part of airguns because my previous ones I could fill with a normal 3000 psi scuba tank but that’s not the case with my taipan.
