Query: Canon Wireless Remote Control

Everything works fine. Except for one CRITICAL shortcoming. I'm a mountaineer and often take group shots outdoors. Sometimes the camera needs to be MORE than 16 feet from the group, because of rough terrain or desired angles. At that distance the remote would not work consistently, so I would have to walk closer to the camera to activate it. However, the remote / camera firmware replaces the 9-second countdown that the onboard camera timer has with only 2 seconds. Meaning that I have only 2 sconds to re-join the group. Forget it. I might as well just run from camera to group in 9 seconds.I think this product was designed by engineers who never use or field test their own products.
