Frequently Asked Questions
Which handheld marine VHF radio has GPS and DSC?
The Standard Horizon HX890 combines built-in GPS with Class-H DSC, which lets you send a digital distress call with your position when properly set up with an MMSI. It also floats and has 6 W transmit power, but it doesn’t include AIS.
What is the difference between IPX7 and IPX8 for a marine radio?
IPX7 covers temporary immersion, while IPX8 is for longer or deeper immersion under conditions set for the device; the rating alone doesn’t give one universal depth and time. For a concrete comparison, the Standard Horizon HX890 is rated for submersion to 1.5 m for 30 minutes.
How far can a handheld marine VHF radio transmit?
A handheld’s practical range depends on the radio’s height, antenna, output power, and obstructions between you and the other station. Use it as a short-range communications tool and rely on a fixed-mount radio with a higher, properly installed antenna when you need more reach.
Can a handheld marine VHF radio replace a fixed-mount radio?
No. A handheld is best treated as a backup or close-range radio, not a full replacement for a fixed-mount set.
How do I set up an MMSI for DSC distress calling?
Get an MMSI through the appropriate registration route for your vessel, then enter it into a compatible radio’s DSC settings and follow the radio’s setup prompts. The Standard Horizon HX890 has GPS and Class-H DSC, so it can send a position with a distress call once it’s configured with your MMSI.
Conclusion
Choose the Atlantis 275 if you want a floating radio with speaker-clearing and selectable output; choose the IC-M73 if longer runtime matters more than a floating design. For alerts after a drop, the IC-M37 adds flashing and an alarm, while the BlueBound 350 offers Tri-Watch monitoring. Consider which charging setup and carry style fit your boat.
