Uniden Atlantis 155 Handheld Two-Way VHF Marine Radio, Floating IPX8 Submersible Waterproof
Quick take
The Uniden Atlantis 155 is a compact floating handheld VHF marine radio built for water use, with an IPX8 submersible waterproof design, NOAA weather alert monitoring, and a dual-color backlit display for readability day or night. It’s generally praised for straightforward setup and everyday usability, plus a monitoring feature that adds a layer of safety awareness. The main caveat to consider is that scan/watch behavior may cause audio gaps, and some buyers report accessory fit and battery-charging expectations that can affect convenience.
Pros and cons
Pros
- Floating handheld design with IPX8 submersible waterproofing for on-water peace of mind.
- NOAA weather channels and weather alert monitoring, including multi-channel alert scanning.
- Large, dual-color backlit LCD display intended for day and night viewing.
- Easy channel selection and usability features like a lock function, plus support for 3W or 1W transmit power.
- Battery system includes rechargeable NiMH AAA cells and a DC charging cable in the box.
Cons
- Watch/scan may not pause when a signal is found, which can create noticeable breaks in received audio.
- Charging convenience may be limited if you expect a mains wall charger option instead of DC charging.
- Some buyers report belt-clip durability issues, and battery life can depend on using the right rechargeable AAA cells.
What buyers think
Buyer-review evidence is fairly consistent around day-to-day usability. Many comments describe the Atlantis 155 as easy to learn, quick to operate after reading the guide, and simple to use on the water for routine channel selection. Battery performance also comes up often, with multiple reports that it can last for days when used sensibly, and longer runtime when the unit is paired with appropriate rechargeable AAA NiMH replacements. The display and controls receive positive notes as well, especially the large, backlit screen and the ability to prevent accidental channel changes. Where feedback varies, some buyers note limitations with watch or scan audio behavior (audio gaps while scanning), and others mention accessory or charging expectations, like belt-clip strength and how charging is handled.
Who this radio is best for
The Uniden Atlantis 155 is a good fit for boaters, kayakers, and other water recreation users who want a compact handheld VHF radio that stays easier to manage when conditions get wet. It makes sense if you value:
- Water safety durability: IPX8 submersible waterproofing and a floating form factor for use near the water.
- Readability in changing light: a dual-color backlit LCD screen for daylight and nighttime viewing.
- Routine monitoring: NOAA weather alert coverage designed to keep weather information in the mix.
- Simple operation: quick channel selection, plus a lock function to reduce accidental changes.
Key features that matter on the water
Floating and IPX8 waterproofing
The Atlantis 155 is designed to be both floating and IPX8-rated for submersion protection (helpful for the kinds of accidental drops that happen with handheld gear). That combination is a major reason people choose this style of radio over smaller, non-water-focused handheld models.
NOAA weather and alerts
It receives NOAA weather channels and weather alerts. Buyers who prioritize situational awareness often like having weather information available during outings, and some mention the alert monitoring behavior as part of why they feel more prepared.
Display and controls
A large LCD with dual-color backlighting is intended to make channel and status information easier to read day or night. The radio also includes a lock feature to help prevent accidental channel changes when it is clipped on or handled frequently.
Transmit power and practical range
The radio supports user-selectable 3W or 1W transmit power, which can help you balance stronger transmissions against longer battery life depending on your situation. The device is rated for VHF marine use with a listed maximum talking range up to about 15 kilometers (conditions can vary widely in real life).
Battery system and charging setup
The unit uses four AAA cells (NiMH rechargeable batteries are included) and includes a DC charging cable. Battery runtime is frequently described as lasting several days for regular use, but a recurring theme in the feedback is that performance can depend on using the right kind of rechargeable AAA NiMH cells.
Pros and cons in plain English
Why it works well for many buyers
- Easy to get going: the setup and channel navigation are frequently described as straightforward.
- On-the-water usability: the screen, lock function, and compact handheld design help reduce friction when you are busy managing the outing.
- Weather-aware monitoring: NOAA coverage and alert features align with a safety-first use case.
- Manageable power choices: switching between 1W and 3W transmit power supports different tradeoffs.
What could be annoying or limiting
- Scan or watch audio gaps: some buyers report that scanning does not always pause for incoming signals, which can make transmissions harder to follow.
- Charging expectations: if you prefer charging from a standard wall outlet, you may want to plan around the included DC charging approach.
- Accessory durability: there are mentions of belt-clip weakness or looseness, which matters if you plan to rely on clip-on carry during active use.

Is the Uniden Atlantis 155 worth it?
The Uniden Atlantis 155 is worth considering if you want a floating, IPX8-rated handheld VHF radio with a bright dual-color backlit display and NOAA weather alert support, and you value ease of use for regular channel monitoring. It may be less appealing if you depend heavily on scan/watch listening and strongly prefer that the radio pauses scanning when a signal appears, or if you need a specific charging setup (like mains charging) and a very robust belt-clip for active movement.
Alternatives to consider (how to choose)
If you are comparing options in the handheld VHF category, focus on these decision points rather than brand alone:
- Water rating and floating design: prioritize submersible ratings and whether the radio floats.
- Display readability: look for dual-color or high-contrast backlighting for night use.
- Weather alert capabilities: confirm NOAA weather channel coverage and how alerts integrate with scanning/watch modes.
- Battery and charging flexibility: consider whether the model charges from USB/DC, a wall adapter, or both.
- Audio behavior during scanning: if you rely on watch/scan, check how the radio handles incoming signals during scanning.
