Uniden Atlantis 275 Handheld VHF Marine Radio - Compact 6W Power

Our review of the Uniden Atlantis 275 finds a compact, purpose-built VHF handheld that suits boaters who want reliable long-range communication and tough waterproofing without bulk. The single biggest reason to buy is its combination of 6-watt transmit power in a submersible, floating package with a very readable dual-color LCD, making it easy to use both day and night when safety or contact matters most.

Key Features

• 6 Watt Transmit Power: Offers selectable 6W, 2.5W, or 1W output so users can prioritize range or battery life depending on conditions.
• Submersible IPX8 Waterproof: The radio meets IPX8/JIS8 standards and clears its speaker of water after submersion, which increases reliability in wet marine environments.
• Floating Design with Emergency Strobe: Floats and includes an emergency strobe light and built-in flashlight for visibility and safety if dropped overboard or used in low light.
• Large Dual-Color LCD: The largest screen in its class (25mm x 40mm) with paper white backlight for daytime and red backlight for night makes channel reading and status checks simple.
• Full Channel Coverage: Receives all USA, Canadian and international marine VHF channels including four-digit channels and Canadian B channels, plus NOAA weather channels and alerts.
• Included Charging and Battery: Ships with a built-in Li-ion battery pack, AC and DC charging cables, and a charging cradle so it is ready to use from the box.

Who It's For

The Atlantis 275 is aimed at recreational boaters, anglers, and small-boat operators who need a durable, portable radio with real range and dependable waterproofing. It is a good match for anyone who values straightforward controls, NOAA weather alerts, and the flexibility to boost transmit power when heading offshore.

Those who require integrated GPS position reporting or a fixed-mount solution for continuous onboard use should look elsewhere; the Atlantis 275 is a handheld focused on portability and ruggedness rather than advanced navigation features.
