Hand helds are great for portability. I have one in my camper mostly for listening. I can hear much further then I can talk.
For very little more the radio in your boat will give you more bang for your buck with extended talk range.
Standard Horizion has a 3 year warranty and they fixed mine after it was four years old at no charge.
The DSC Distress feature is a very easy way to call for help if needed. (I don’t use it for regular DSC calling, just Distress)
Class D Digital Selective Calling
The ECLIPSE DSC+ is Class D class VHF with a separate Channel 70 receiver, which allows DSC calls to be received even when listening to traffic on Marine VHF channels. The DSC DISTRESS function when activated transmits a digital MAYDAY including vessel identification, Latitude / Longitude and time (with GPS connected), to facilitate prompt response. Additional calls that can be made are Individual, Urgency and Safety.
