The Unication G1 has to be the toughest pager on the market today! Superior ruggedness, Water/Dust-proofing, another added bonus! loud audio, Awesome flexibility! Including the Zone feature! No false alerting, like the competitor! And CTCSS (PL/DPL) gives you peace of mind to block out any neighboring County traffic that you may have! Go with a Unication G1! You won't regret it! Once I got one, and loved it, my whole department switched, and hasn't looked back!!!
