You now have the best of both worlds in one easy-to-use, reliable wireless trigger. The Plus IV Auto-Sensing Transceiver allows photographers the benefit of on-camera TTL flash combined with remote manual flash. Whether you shoot portraits, weddings or sports, having the ability to combine on-camera TTL flash with remote manual flash provides you with a huge competitive edge.

On-Camera TTL Flash / Remote Manual Flash
The Plus IV features a top shoe providing TTL compatibility with most Canon, Nikon and Panasonic cameras and flashes as well as some Fuji and Olympus gear. This allows photographers the versatility to shoot with an on-camera flash in TTL mode while triggering their remotes in manual mode. Easily slide a speedlight into the top shoe of your receiving radio and you are ready to start triggering your remote flash in minutes. A perfect setup for wedding photographers.

Top Shoe
The top shoe on the Plus IV allows photographers to easily set-up their speedlights. No sync cord required.

Simple User Interface
The Plus IV has an intuitive user interface where all channels, zones and modes can be easily engaged via a soft-touch keypad and displayed on an easy-to-read backlit 2.5cm (1") LCD display. When you're working in dark environments, simply press any key other than TEST to illuminate the LCD.

32 Channels
With 32 channels (16 standard plus 16 Quad-Zone Triggering channels), the PocketWizard Plus IV Transceiver enables you to trigger individual or groups of lights simultaneously or individually. This is critical for working in crowded venues or with multiple lighting set-ups.

Quad-Zone Triggering
Selective Quad-Zone Triggering keeps you shooting photos, not running back and forth to your lighting or cameras. Without leaving the camera position, you can wirelessly activate or deactivate your remote flashes or cameras in 4 separately controllable zones: A, B, C or D. This is ideal when using multiple lighting setups or turning remote cameras or flashes on and off as needed.

Auto-Sensing Transceiver
With their patented Auto-Sensing Transceiver technology, the Plus IV Transceiver is one smart radio. When set to TxRx, it will instantly and intelligently switch between transmitter and receiver modes as needed for greater flexibility on the job. The Plus IV may be set to transmit (Tx) or receive (Rx) independently if needed.

Two-Stage Remote Camera Triggering
The Plus IV Transceiver is the perfect solution for remote camera triggering. The unique two-stage TEST button on the Plus IV works just like the shutter release button on your camera. Press it halfway and your remote camera wakes up to meter and focus. Press TEST all the way to take your photo. When released, your remote camera will return to sleep mode normally; a real battery saver.

Auto-Relay Mode
PocketWizard Auto-Sensing Transceiver technology lets you trigger a remote camera in sync with remote flashes using only 3 PocketWizard radios: the one in your hands, a Plus IV cabled to your remote camera and the one connected to your remote flash set to one channel higher.

Long Range Capability
Range is comparable to other PocketWizard radios. Shooting environments are seldom ideal, so the Plus IV incorporates two range extending modes for the challenges of the real world. Use Long Range Mode (LR) to nearly double the effective triggering distance in almost any environment.

Repeater Mode (RP)
In very challenging environments or extremely long working ranges, place a Plus IV in Repeater Mode (RP) between your transmitter and receiver to repeat the signal and complete the connection. These modes take a little extra time to do their jobs, so maximum X-sync may be reduced when firing remote flashes in LR or RP modes.

High Speed Receive
Normally, the Plus IV is capable of triggering lights or cameras at a sustained rate of up to 12 frames per second (FPS), with a standard for PocketWizard radios. Set the Plus IV to High Speed Receive Mode (HSR) and trigger at rates up to 14.5 FPS, beyond the capability of most of today's cameras. This mode can also help high FPS triggering compatibility for any flash. TTL operation reduces the fastest FPS a system can use.

External Power and Firmware Upgradeable
The Plus IV is normally powered by two AA (IEC:LR6) batteries. For long term remote placement, use an AC adapter, like the PW-AC-USB Adapter, that plugs into the standard Mini-B USB port of the Plus IV. The USB port also enables future upgrades of the Plus IV operating system.

PocketWizard Compatible
The Plus IV is compatible with all Standard channel or simple triggering PocketWizard radios of the same frequency including PocketWizard-enabled photo gear from Profoto, Dynalite, Norman, Photogenic and Sekonic light meters. The PocketWizard wireless system allows for total flexibility with whatever lights or cameras you may be working with.

Basic Compatibility
The Plus IV is a radio transceiver, capable of acting as a transmitter or receiver for triggering remote flashes and cameras. It requires at least one other PocketWizard radio for wireless triggering. It can be connected to almost any remote flash via the top shoe or connected to almost any camera with the proper cable.

Detailed compatibility
Compatible for use with industry standard hot shoes, PC sync terminals, etc. Safe 3 volts sync voltage for modern digital camera systems. Compatible with most flashes and triggering circuits. Can handle up to 300 volts.

Plus IV Operational Considerations
• Nikon Cameras with MC-DC2 ports do not provide half-press or full press output through the MC-DC2 port. This means that any camera using an N-MCDC2-ACC cable won't be able to provide the "half press your remote camera from the camera in your hand" operation when using the shutter release button. This affects the following cameras: D90, D7000, D5100, D5000 and D3100
• Nikon Camera's with a MC-DC1 port using an NM4-ACC cable does not provide "half-press" output, but it does provide "full-press" output. This affects the following cameras: D70s and D80
• Compatible with flashes up to 300 Volts
