Very Cool Optical Slave Unit

This device triggers the slave flash simultaneously with the main flash. Certain flash settings on digital SLR cameras may not be compatible. It offers an extended battery life, capable of up to 300 hours of use or more. If the device is not switched off after use, it will automatically shut down after 15 minutes of inactivity. With limited usage, the battery life can last approximately 10 months. When the sensor is pointed towards the camera flash, it has an operational range of about 25 square feet indoors in rooms with a white ceiling. Additionally, it can trigger at much closer ranges using reflected light.

The described device functions as a wireless flash trigger, designed to synchronize the firing of a slave flash with the main flash of a camera. This is particularly useful in photography where multiple light sources are needed for enhanced illumination. The compatibility issues with certain flash settings on digital SLRs may arise from differences in triggering mechanisms, requiring users to ensure that their camera settings are appropriately adjusted for optimal performance.

The device's extended battery life is a significant feature, allowing for prolonged usage without the need for frequent replacements. The automatic shutdown feature after 15 minutes of inactivity conserves battery power, enhancing the overall lifespan of the unit. The operational range of approximately 25 square feet, especially in environments with reflective surfaces like white ceilings, indicates the effectiveness of the sensor in detecting the main flash. This capability is essential for achieving desired lighting effects in various photographic settings.

For optimal performance, it is advisable to position the sensor directly towards the main flash source to ensure reliable triggering. The ability to trigger the slave flash at closer ranges using reflected light provides versatility in creative lighting setups, enabling photographers to experiment with different angles and intensities of light. Overall, this device is an essential tool for photographers looking to expand their lighting capabilities and achieve professional results in their work.Fires the slave flash exactly when the main flash occurs. Some flash settings on digital SLR`s are not compatible. Long battery life, 300 hours of use or more. If not turned OFF after use, the unit will shut down after 15 minutes of inactivity. Battery life, with limited use, is around 10 months. Pointing the sensor towards the camera flash give you about 25 ² operating range indoors in rooms with a white ceiling. It will also trigger at much closer range from reflected light. 🔗 External reference
