Uncover the Secrets Behind Flash Duration

Knowing the flash duration of your lights is the first step in freezing fast-moving subjects like water splashes, dancers and athletes. For the first time ever, photographers can now quickly and easily measure flash duration for precise exposure control.


The First Meter to Measure HSS

Finally, photographers now have an accurate way of measuring their lights when they want to overpower the sun or achieve a very shallow depth of field using Hi-Speed Sync.


More Freedom Through Wireless Triggering

With the PocketWizard module photographers can easily trigger any PocketWizard wirelessly and control the power of their lights with any Control TL Compatible Unit.
With the Combined Elinchrom & Phottix Module, photographers have full Skyport triggering and power-control capabilities, while Phottix users have Strato II and Ares II triggering capabilities.


Substantially Improved Low-Light Accuracy

Capable of reading down to 0.1 lx of illuminance, precisely metering scenes lit by candlelight or getting the right measurement for long-exposure night photography is now a possibility.
