Anybody very familiar with the Eicon? The transmitter is what intrigues me. It looks very similar to a walkie-talkie and phone. does it do more than just turn the zones on and off? Does it display the zones? Can it be used as a universal remote separate from the Irritrol that is built for it? Any info would be greatly appreciated. Purp knows a ton on the Eicon but he is geocatching. Mike may answer this but the Rain Master currently on Ebay has a flat transmitter keyboard unlike the rounded ones of the current version. I recall that RM changed their transmitter keyboard and had a lot of problems with it which have since been corrected. Was it the flat surface version that had all the problems? I may call RM and see if it can be upgraded to the current keypad.
