I have had 3 visos earlier. Two of them were broken by itself. (though L&B has great customer support and they replaced those units) The last one was lost in freefall once the velcro wristband came undone. I then decided not to get a fourth one and decided to go another route.
I have had 2 Sunnto watchs "vectors" stop working for no apparent reason as far as the altimeter goes.What I mean by that is both watchs have reset altitude to 0 on exit (even though they read fine on the way up), both have give erroneous reading in freefall, also both have switched off that screen in freefall too. Also it should be noted even Sunnto does not recommend them for skydiving.
L & B has finally figured out mounting for their Viso. They fit inside a plasitc/rubber housing very securely now.
