The hahnel Giga T Pro 2.4 GHz Wireless Timer Remote for Canon combines the functions of a wireless remote shutter release and a remote timer into a single very useful accessory operating at 2.4 GHz with a range of 328'. Using the small, lightweight receiver and transmitter (batteries included) you have access to programmable features such as a self timer, interval timer, long exposure setting, and exposure count–all of which may be used in any combination, making the possibilities nearly limitless. There is no limit to the possible number of exposures, and an exposure as long as 99 hours, 59 minutes and 59 seconds can be programmed.
The Giga T Pro II has a Transmitter On/Off button to save battery power. It also has two timing loops, one embedded in the other. This allows you to repeat the original timed program as many times as required. You can also use the original program feature to create a timed 10-minute series of astral shots. You can then set this program to repeat at hourly intervals. In addition, you can set up a basic program which allows you to set up a timed shooting sequence, defining the delay, number of shots, interval shots and so on.
