I recently purchased a G1 because I was tired of carrying two different pagers. One for work and one for the FD. I wanted a pager that could hold multiple tones and channels, and at the end of the day I could just change the knob to position 1 and have it go off for my FD tones only. So I purchased a G1 and have been very happy with it! It's very rugged and very customizable when it comes different settings. I'm very happy with the pager and I'm trying to convince my FD to switch to the G1.
