A kayaker's view on this.  Easy to use radio.  Weather function is nice.  This radio is for on the water use only.  Just like all other VHF marine radios.  Do not use this device to communicate while on land.  Also read manual to better understand the regulations.  Comes packaged in a blister pack.  Sharp object needed to open.  Battery life is great.  Waterproof tested it myself in vat of water.  Use this radio for kayaking or as a back up to your marine radio on a bigger boat.  As with all electronics, keep away from your navigational compass.
