The problem I see with automated units is they deflate at a set rate.
A manual unit, that rate of deflation can be controlled. So, if the
auto unit deflates and the sound/bounce of the heartbeat occurs after
or before the true pressure --old springs, battery, whatever-- the
true reading is wrong. I can slow a manual unit's deflation down to a
speed where the heartbeat point is more easily dectected and a more
accurate pressure is read.

Jes my take on it. You do as you like. I get my new manual unit on
Wed. I already tossed the Amron.

However, unless you suffer from tachycardia (abnormally fast heartbeat),
the automated deflation cuffs have been engineered to accurately and
rapidly measure the changing pressures as they happen. It's a
non-issue. Many doctors offices and hospitals use fully automated
inflation/deflation digital blood pressure machines.
