We understand your concern with regards to the use of AAD’s during high speed landings, but first we would like to explain the working principles and functionality of the Vigil 2+ Xtreme.
A Vigil Multimode in “PRO” setting will activate when reaching a measured rate of descent of 35 meter/sec in the activation zone. A Vigil Xtreme requires 43 meter/sec in the activation zone.
When a skydiver enters the activation zone at terminal velocity, this would not make a difference, and both units will activate at the same time. However, when a malfunction would occur, and the skydiver needs to cut away his main, it will take longer to reach the activation speed of a Vigil Xtreme than for a Vigil Multimode in “PRO” settings, especially when cutting away from a “spinning malfunction”!!
This is also the primary reason why VIGIL AAD has chosen for an activation speed of 43 meter/sec, and not 46 meter/sec as this may even cause longer delays.
By doing so, we do not wish to discourage you from choosing a Vigil Xtreme, we just want you to be aware of the required and increased activation speed on a Vigil Xtreme.
We leave the decision to use a Vigil xtreme up to each individual. We cannot determine remotely whether you can/will reach the required activation speed of a Vigil Multimode.
If you are planning to attend a skydiving event in the near future where a Vigil promoter is present, we can supply you with a test unit that can measure your vertical registered speed under canopy. This can give you a better idea on what type of measured speed you are generating under canopy and on landing.
The reading of a Dytter, Altitrack, or any other device is not comparable/reliable with the reading of a Vigil, as these devices are placed on a variety of different locations than a Vigil, and have a different algorithm and calculation compared to the reading of the Vigil AAD.
We hope we were able to provide you with some more in depth information, and to help you with the choice of your Vigil. If you should have more questions, please don’t hesitate to contact us!
