A technical comission prooved some safety systems in germany. They test the power, which is necessary to release the system.
The results are very interesting ! Systems with an pin QR like maui magic (coppy of Wipika or Takoon) are needing a lot of power to release. You have to pull with 30-50kg!!
Naish X2 loop need 20-40kg !! At a traction from 295kg Naish loop brocke !!
All participants have problems the quality.
Only the Kiteproshop bar was testet very good. The safety is easy to release. You have to pull only 5-6kg.
