most compact 1st stage?

[black1]

Hi everyone. I use Atomic M1 and Z2 regs which come with nice 1s stage connector's but im looking for more compact, small and lightweight one's to use. Im putting an H valve on one of my tanks and want to use 2 small 1st stage's that are not heavy nor bulky, got any suggestions?

I think the AL Mikron fits the bill!

I was looking into this also for a light travel reg, I have the older AL Micra ADJ which is a very small and light 2nd stage, but the Cousteau 1st stage is very bulky and very heavy. I think the Mikron 1st stage would be perfect it is apparently about the size of a golf ball although it is still apparently a little heavy. the problem is finding just the Mikron 1st stage? I was under the impression that AL did not sell their stages separately but as reg sets, I could be wrong, often am. If anyone knows where to get the Mikron 1st stage only please let me know. Cheers.

PS the Apeks "Flight" looks very compact.

The Apeks US-4 first stage is also very small, and can be purchased separately.

Yeah that is the problem i seem to be having is that most dont sell the first stage seperatley, only with a reg set, will try the Apeks.
