All the published ranges are wildly exaggerated. If you were stood on a mountain top looking across a lake to another mountain top with a clear LOS & perfect atmospheric conditions then they might be valid.
You'll also need an FCC License to use GMRS & that ain't cheap!
Having said that I've been impressed with the
Midland GXT650, which I've been using for a few years.
Good:
Range (not 25 miles but I did get almost 8 in wooded hilly country).
Display
Keyboarding ability.
features (including Low power FRS channels)
Runs on either its own rechargeable battery pack or "AA" non-rechargeable batterys.
(It will run on "AA" rechargeable too, but the low battery warning is always on).
Came with accessories like car & A/C chargers, earbuds, mic boom earbuds & so on.
Not so good:
Vox is slow
Speaker is small & fairly quiet.
Belt clip is weak, (But removable)
MENU button is too easy to hit accidentally.
A bit gimmicky (animal call call alert tones) & so on.
Accessorys are available including boom mike/ headset witch is hands free, or my preference a "surveillance mike earbud" which is way better IMO.
