7 hop and pops and 1 to 14.000 ft using Smart Alitmeter.
Comparing it in the plane against a couple of Viso’s and my Analog alti.
I found it supprisingly accurate. As did other jumpers.
It stays on, so long as you don’t swipe or bump the side button. It turn off in the plane twice over 7 jumps, but is easy enough to turn on again and picks up the correct altitude. Once I’ve landed the next time I look at it, it’s turned off and back at home screen (watch face) I think that happens when I pick up my canopy, it’s a good thing otherwise it would drain the battery quicker.
Battery 100% - Starting at 7am I had 4 jumps (3 hop & pops to 5000 / 1 to 14.000) before the low battery warning light went on around 6pm. To concerve battery, I did not play with the watch at all between jumps and only turn Alti on shortly before boarding plane setting it to ZERO.
I am using it for canopy work, found out the reason why it’s best worn on the inside of wrist. 😀
Visual in color scene daylight and under canopy excellent. During freefall I have no idea.
TROUBLE SHOOTING
Once on go to Settings and Comectivity - Bluetooth must be off as also WiFi.
We need approved Altimeters at our DZ’s. As I never intended to use it as my only Alti, I can say I’m happy with it and it does a good job.
