Portable components always work easiest when you do not have to think about them. This was the basis on which the EK 100 G3 was developed. Its adaptive-diversity technology provides excellent reception at all times. This receiver is designed to securely attach to a camera's shoe using a clamp mount. The EK 100 G3 also can synchronize to a G3 transmitter with a simple push of a button. The EK100G3 is compatible with the optional DC 2 external adapter for extended use without batteries where a 12VDC source is available.
