From the moment I got my Optima I was amazed! It calibrates quickly and reads very accurately. Also, the different altitudes it can be set at for both freefall & canopy mode are great. The sirens for the alarms are great & can be adjusted to your preference. I would recommend the Optima for any jumper needing an audible. My only "complaint" is that the access needs to be made easier, rather than waiting to press the button once the icon appears as it can be a little difficult. On a scale of 1 to 10 I'll give the Optima a 9! Great job L&B!
