Jinbei TRQ6N TTL HSS Bluetooth Trigger For Nikon DSLRWow, this is exciting. This trigger can be used like the TR612N but with the additional ability to link with an Android or Apple app . This allows for a Visual confirmation of what every head and group of heads is set to from Power, to modeling and syc settings like TTL, HSS, Rear curtain. Setup custom studios with presets that can be saved. Each head is shown in the app with live readout of its settings.This will become Jinbei's standard remote as it is clear and conscise to use, with very little instruction needed. We highly recomend this trigger as the standard choice for Nikon users.
