## Summary description

Hahnel MODUS 600RT MK II Pro Kit for Nikon is a slave flash unit designed for Nikon cameras. It features a built‑in lithium‑ion battery, black housing and an approximate recycle time of 1.5 seconds. The unit is battery‑powered and intended for on‑camera or off‑camera use as a slave flash in multi‑flash setups, event and studio photography.

## Long description

The Hahnel MODUS 600RT MK II Pro Kit for Nikon is a pair of slave flash units engineered for Nikon systems and multi-flash workflows. Each speedlight has a black housing and a built-in lithium‑ion battery that supports fast recycling of approximately 1.5 seconds, allowing sustained shooting during events, portraits and on-location sessions. The kit includes two MODUS 600RT MK II speedlights, a Viper TTL transmitter for remote control, two HLX-MD1 Extreme batteries, a USB-powered MD1 ultra-compact charger and a USB cable for convenient charging.
Advantages
The units provide TTL-compatible slave operation with reliable recycle performance thanks to the integrated Li‑Ion power source. Compact black housings and consistent output make the flashes suitable for both on-camera fill and coordinated off-camera lighting setups. Included accessories—transmitter, spare batteries and compact charger—simplify portable use and reduce downtime during continuous shooting. The approximately 1.5 second recycle time enables faster sequence capture compared with typical AA-powered alternatives.
Suitable for
 Event and wedding photography where multiple flash units are needed
 Studio portrait sessions requiring off-camera flash coordination
 Location and outdoor shoots that demand compact, battery-powered lighting
 On-camera fill flash for Nikon cameras
 Multi-light setups controlled via a wireless TTL transmitter
Key specifications
 Flash type: external speedlight for Nikon-compatible systems
 Power source: built-in lithium‑ion battery for each flash
 Approximate recycle time: ~1.5 seconds under standard conditions
 Color: black housing
 Wireless control: compatible with included Viper TTL transmitter for remote TTL and manual control
 Kit contents: two speedlights, wireless transmitter, two spare batteries, USB-powered charger and USB cable
How to use
Install the built-in lithium‑ion batteries and charge them fully using the supplied MD1 ultra-compact USB charger before first use. Mount a speedlight on the camera hot shoe or position it off-camera on a stand, then pair it with the Viper TTL transmitter following the transmitter pairing procedure for Nikon. Set the camera to the appropriate TTL or manual flash mode and adjust flash output, zoom and angle on the unit or via the transmitter as required. For multi-flash setups, designate one unit as a master or rely on the transmitter to trigger all slave units simultaneously.
Usage recommendations
For reliable performance, keep batteries charged and carry the spare HLX-MD1 battery included in the kit. Allow brief pauses between long continuous bursts to maintain the stated recycle time and avoid overheating. Use stands or modifiers to shape light and maintain consistent output across multiple units when shooting events or group portraits.
