Re: [Ron] Altimeters Digital vs Analog newbie
[In reply to]
having worked in aviation from the transition from analog to digital cockpit instruments, I've seen quite a few papers written on the subject.
analog are easier to read, and by that, I mean you can quickly 'read' them. take a watch as an example, you can sneak a quick peek at one to get a general idea of what time it is, and you can also take a bit longer to get a more accurate reading. with analog, you get a relative reading and something to reference the needles movement against.
digital will more than likely always give you a more accurate number, but you cant see trends and you don't get any reference.
a lot of aviation instruments or displays will combine analog with digital for the above stated reasons.
I use analog for free-fall, it's easy to glance at and get a relative idea as to where you are from break-off. I like the digital under canopy as I'm looking for more accurate altitudes
you need to decide for yourself which you want to use, I bet you can borrow to help you decide.

Having had two Altitracks (one went through the washing machine; the other "disappeared"), I bought a VISO II and really like how easy it is to read and the fact that in freefall you can easily toggle between displaying altitude and displaying vertical speed which is important to me as I practice different fall rates to improve my big-way skills.
I also like the VISO II because it sits flat on the back of your hand and takes up far less room than an altitrack or Galaxy. (I also have a Galaxy Extreme permently mounted to my harness which is great under canopy and when my hands are where I can't see them.
Digital appear to be more accurate because they give a 'number' rather than a 'close to' value. They may or may not be more accurate.
I've been jumping the same altimaster II for 30 years. On a chest strap mount. From the days when we look at the other guys altimeter. But, I mounted mine with 3000' straight out from my body rather than zero. This way I knew what straight out meant, it was easier to see the needle when at the 'action' altitude and never have needed to read the numbers on the face. Now, wearing trifocals, I can take them off for the jump and still 'read' my altimeter. I know at least one other person above said with trifocals they liked the digital better. YMMV.
I also have a Altimaster III for my hand but when I wear it I almost never look at it.
Bottom line, pick what you want, learn it's issues and advantages, and don't drop it on the concrete several times.
