Haertig, thanks for posting this up.

I just emailed the company - turns out the have a 6 lead option as well. I'm interested to see if I could buy one for use outside the hospital/clinic setting. Unfortunately, only shows the limb leads, but it's still pretty impressive.

I've been contemplating a portable ultrasound too; the combo would do a good screening job for a lot of conditions (all work related purchases, not just a personal EDC)
