Uniden UM725 25W Fixed Mount VHF Marine Radio - Text Messaging - IPX8 Waterproof - White
Important: FCC Ship Station License may be required for installation and use on certain vessels. MMSI registration is required to use DSC emergency calling features. Check requirements at fcc.gov before deployment.
The Uniden UM725 represents the base model in Uniden's advanced 725 series, offering 25-watt VHF performance, IPX8 submersible protection, and unique VHF text messaging capability at an accessible $155.99 price point. While it lacks built-in GPS (requiring an external receiver for full DSC functionality), the UM725 delivers professional-grade features including boat-to-boat text messaging, dual watch monitoring, and industry-leading IPX8 waterproof rating that exceeds the IPX4 protection found on competing radios.
Perfect for boaters with existing GPS systems or those planning to add external GPS later, the UM725 connects seamlessly to chartplotters via NMEA 0183/2000 for position sharing. The standout text messaging feature allows private communication with other Uniden 725-series radios over VHF channels - ideal for coordinating with fishing partners or cruising groups without broadcasting conversations to all nearby vessels.
KEY FEATURES:
- VHF Text Messaging: Private boat-to-boat text communication over marine channels (Uniden to Uniden)
- IPX8 Submersible Rating: Survives temporary submersion (4.9ft for 30min), exceeding IPX4 splash resistance
- NMEA 0183/2000 Compatible: Connect to external GPS and chartplotters for position sharing
- DSC Emergency Calling: Digital distress signals with GPS position when external GPS connected
- Dual Watch Monitoring: Monitor Channel 16 and working channel simultaneously
- 25W/1W Power Output: Maximum range on high power, battery conservation on low
- Large LCD Display: 68mm x 38mm screen shows channel, messages, and status
- All Marine Channels: USA, International, Canadian channels plus 10 NOAA weather
- Remote Microphone Capable: Optional second station operation (mic sold separately)
TEXT MESSAGING CAPABILITY:
- Private Communication: Send messages to specific boats without broadcasting over voice
- Fishing Coordination: Share spots and information discreetly with your group
- Fleet Management: Coordinate multiple vessels without cluttering voice channels
- Compatibility: Works with all Uniden UM725 series radios (UM725, UM725G, UM725GBT, etc.)
- Radio Keypad Entry: Type messages using radio buttons (or upgrade to UM725GBT for smartphone Bluetooth texting)
WHY CHOOSE UM725 BASE MODEL:
- great value: $155.99 is lowest in 725 series - save $21 vs GPS models
- Have GPS Already: If you own a chartplotter, connect via NMEA instead of paying for redundant GPS
- Text Messaging: Unique feature unavailable on Standard Horizon or Garmin at this price
- IPX8 Protection: Superior waterproofing vs IPX4 competitors
- Upgrade Path: Start here, add external GPS later if needed
IDEAL FOR:
- Boats with existing chartplotter GPS systems
- Fishing teams wanting private text communication
- Budget-conscious buyers planning to add external GPS later
- Vessels requiring superior IPX8 waterproof protection
- Boaters prioritizing text messaging over built-in GPS
- Fleet operators coordinating multiple vessels discreetly

GPS OPTIONS:
For full DSC position reporting, connect an external GPS receiver (Uniden MRN-GPSK $80-120) or connect to existing chartplotter GPS via NMEA 0183. If you don't have GPS yet and want all-in-one simplicity, consider the UM725G ($176.99) with built-in GPS for just $21 more.
COMPARISON:
UM725 ($155.99): Text messaging, IPX8, no GPS - best for boats with existing GPS
UM725G ($176.99): + Built-in GPS - best for boats without GPS
UM725GBT ($220.99): + GPS + Bluetooth smartphone texting - premium features
Frequently Asked Questions
Q: Can I text any VHF radio or only other Uniden radios?
A: Text messaging only works between Uniden UM725 series radios. This is a proprietary feature not compatible with Standard Horizon, Garmin, or other brands. Voice communication works with all marine VHF radios regardless of manufacturer.
Q: Should I buy this or the UM725G with built-in GPS?
A: Choose the base UM725 if you already have a chartplotter with GPS that you can connect via NMEA - save $21. Choose the UM725G if you don't have any GPS on your boat and want an all-in-one solution. The $21 difference is much cheaper than buying external GPS separately ($80-120).
Q: What makes IPX8 better than IPX4?
A: IPX4 (found on competitors) protects against splashing water. IPX8 (UM725) survives temporary submersion up to 4.9 feet for 30 minutes. This means the UM725 can handle more severe conditions like large waves washing over the helm or accidental drops in water.
