rakkers

Not comfortable. Won't keep your head warm. Won't protect much. Irritates your ears. Save up and buy a better one.

The only thing this optima does not do is record your jumps, but that is of no benefit to you when you are in the sky anyway. Who cares if you jumped at 12800 or 13000ft?

In the plane I was with a girl and a guy who also had optima's (3 optima's). We put them next to each other and they read the exact same altitude (per 10ft!). As the plane climbed, all the altitudes changed simulataneously.

This is an accurate auidible which gives you many options of when you want your free fall and canopy warnings to go off. I recommend it to any skydiver, not just swoopers.
