Absolutely the best pager hands down. I am a very loyal M guy and after having those pagers and my vhf Unication there is no question about it. The receiver is much stronger, the audio clarity is top notch and the water resistant by far is the best feature. I like the fact that you have so many features that are useful there is not a lot of things on there that are "clumsy" or useless. The fact that there is updates for firmware to make it more friendly is a huge plus. I have had mine and have recommended to others for purchase and have recommended to our county fire assn for purchase. I have talked to the guys at Unication at different trade shows including local ones and fdic, the folks take time to listen, explain their product and when you offer a suggestion they do listen.
So in conclusion take it from a 18 yr veteran and radio guy if your on the fence to which pager you should buy I strongly recommend the Unication line, it won't let you down, you get more bang for your buck, yea the size might be a little bigger then its competitor, but it's worth it when it goes swimming in a dump tank or you drop it from a ladder. I'm in the market to purchase the new g5 for our 700&vhf system and can't wait to see what features it has in store.
