The ELB 400 and the Quadra Ranger are one of the strobes on the market that support the ability to trigger above your camera flash sync shutter speed (mostly 1/200th a second), Elinchrom’s solution is called Hi-Sync. This technology takes a slice out of the full-flash curve allowing sync speeds much greater than 1/200th a second. This is why action and sports photographers particularly appreciate this technology.

These 3 flash heads offer you 3 different ways to use your ELB 400 (or Quadra Ranger). The difference in these heads lies in their flash duration.
The Action head offers the fastest flash duration to freeze moving subjects with the normal flash sync shutter speed of your camera (1/200th a second) without the use of Hi-Sync technology. When shooting with a Hasselblad or shooting with a DSLR at the standard sync speed or below, you should use the Action heads.
The Pro head is the standard head for universal uses. It’s the perfect flash for portraits and still subjects. It offers a great balance between performance and price.
When you want to shoot and overpower the sun for a portrait or to stop the motion completely, you should opt for the HS heads in combination with the EL-Skyport Plus HS transmitter. So, if you have an exclusive usage of Hi-Sync (using shutter speed faster than 1/200th), you’ll have to go for the HS head along with the EL-Skyport Plus HS transmitter.
