one is a poppit valve, one is a spool valve. so far no one really know the specs on the geo2 all we know is it has the same electronics, screen and the geo2 will have planets new reg. beyond that is just speculation
well the geo2 is a spoolie and the victory is a popit. I wanna shoot one before i consider it. the first geo was just a simple dump valve, nothing special. The geo2 sounds like a NT design, like a balanced spoolie. BUT the geo2 isn't like NT so.... i dunno...
