Viso2 Spedometer Accuracy

[shibu 1]

I just got a visio2. I jumped with it three times yesterday. My last jump was just a belly dive with a 10sec track. It said my highest speed was 169mph. Is this my vertical speed? How accurate is this? Does this indicate a poor track position? I was under the impression that during a good track your vertical speed will slow as your horizontal speed increases.

Viso, not Visio.

It is vertical speed, but the data is typically "noisy" and can show unrealistic numbers. The people you jump with should be able to confirm if your track is so lousy that you could have been diving that fast.

People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired. I’m certainly not, and I’m sick and tired of being told that I am

Remember that the Viso has Skydiver Airspeed and True Airspeed. SAS compensates for altitude and is a better measurement. I get spurious readings on my Viso though (best speed to date - 850MPh on a hop and pop)

From memory you can replay the jump and watch the speed (read the manual).

Experienced jumper - someone who has made mistakes more often than I have and lived.

So what you are saying is the Felix wasn't the first person to break the sound barrier while skydiving?

Just the first to break the speed of light!
