When I bought my second parachute (1999) I only knew about cypress, as a substitute for Astra and Fxc-12000, which promised to be the best option available. Its useful life was 12 years, every 4 years it had to be sent to the US to update software and there was a device for tandem, another for students and another for expert paratroopers.
As a static line instructor, in 2004 I needed to enable equipment for students, and I learned of the existence of Vigil, which offered 20 years of useful life, did not require software update, the device could be configured as student, tandem or pro, he could fall into the water without being hurt.
The surprising thing was to learn that shortly after the Vigil was launched on the market, Cypress created the Cypress-2, offering those same functionalities to paratroopers, so I decided to invest the dollars in a brand that does care about its customers. From that moment we have used Vigil in all the teams of the "Parachute School" (https://www.escueladeparacaidistas.com/) and we are currently a dealer through Fly Sport (https://flysport.cl/).
Vigil invests in its customers, for example it receives previous units and exchanges them for updated equipment for very reasonable prices.
So far our testimony regarding the best DAA. Greetings and good jumps !!!.
