Being fast with your wingsuit and finding loot first can be very important at the start of each Black Ops 4 Blackout match. There is a trick that lets you reach mid-long range targets a lot faster.
As soon as you jump out of the helicopter, do a nosedive and gain speed until you reach about 70 m/s. Now get back to a horizontal gliding position and aim for your target as you would usually. The difference now is that you keep most of the momentum that you gained from your nosedive.
