Altimeter question

What altimeter puts out the least current when firing pyro charges.

I've been experimenting with my HiAlt45 in a vacuum chamber to fire homemade ematches. It works quite well over a range of different designs. The issue is the HiAlt45 has one of the higher output currents of available altimeters. I would like to test my ematchs on the altimeter that puts out the least amount of current to make sure they will work with that altimeter too.

The MAWD uses capacitor discharge for firing, and when I had it, it couldn't fire much besides commercial e-matches.

You could try using something like an RRC2X (which doesn't have any output capacitors) with a fairly anemic battery.
