Best Waterproof Handheld Ham Radio: Retevis RA89

The best waterproof handheld ham radio is the Retevis RA89, an IP68-rated dual-band handheld that weighs 0.65 lb and charges over USB-C. If you spend your time on the water instead, the Uniden MHS75, a JIS8-rated marine VHF with a 3-year warranty, is the safer buy. Here's the misconception worth clearing up first: most shoppers compare wattage, and wattage is not what decides this. The sealing standard is. A 6W radio that drowns after one wave beats a 10W radio that survives it exactly never.

How I screened these five down to the shortlist

I lined up five handhelds and compared their published specifications side by side. Two of them, the Cobra BlueBound 350 pair, are the same radio in different shells. That matters when you read the table, because their capability is identical and only the colour changes.

Here's how the criteria fell out, in order of weight:

1. A stated waterproof standard. A radio without a published sealing rating cannot be trusted in rain, let alone a river.
2. Weight and size, because a handheld you leave at home protects nothing.
3. Charging and battery, since a dead radio is not waterproof or anything else.
4. Warranty, as a proxy for how long the maker expects it to last.

Only one radio here carries a true IP68 claim: the Retevis RA89. The Uniden MHS75 lists JIS8, a marine submersion standard. The two Cobra units float but publish no ingress rating in this data. The TIDRADIO TD-H9 lists no waterproof standard at all, which shapes exactly where it lands below.

Best waterproof handheld ham radio at a glance

Ham, GMRS or marine VHF: which one do you actually need?

These five radios split across three service types, and the right one depends on who you want to talk to. Buy the wrong service and the licence, channels, and even legality shift under you.

• Ham (amateur): the Retevis RA89 is a dual-band ham handheld and needs an amateur licence in the US. It reaches the widest set of frequencies here.
• GMRS / ham switchable: the TIDRADIO TD-H9 lists a three-in-one model that switches between ham, GMRS, and unlocked modes. GMRS needs its own licence but no exam.
• Marine VHF: the Uniden MHS75 and both Cobra units are VHF marine radios built for channels 16, 9, and NOAA weather. They are the right call on the water and the wrong call on a hiking trail.

A quick way to decide: if you're on a boat, buy VHF. If you're licensed for amateur radio and want dual-band range on land, the RA89 fits. If you want the most flexibility across services in one body, the TD-H9 is the switch-hitter.

1. Retevis RA89 Ham Radio — Best overall

The RA89 is the only handheld here with a true IP68 claim, and it pairs that seal with the lightest ham body in the set.

Best for: hunters and preppers who want a sealed dual-band handheld Skip it if: you need a radio that floats

The RA89 wins on the one specification that defines this whole category. Retevis lists it as IP68 waterproof, dustproof, and dropproof, which is the strongest sealing claim among these five. It's also compact at 4.96 x 1.69 x 2.44 in and just 0.65 lb, so it disappears into a pack or a chest rig. That's the best waterproof handheld ham radio profile: sealed, small, and ready for weather.

Retevis says the 2500mAh battery pushes standby time to 75 hours and charges over USB-C, so you top it up with the same cable as your phone. The maker also lists VFO mode and CHIRP support, meaning you can program frequencies from the keypad or a computer. An intelligent noise-reduction claim rounds out the sheet.

The trade-off is service and buoyancy. This is a ham radio, so you need an amateur licence, and unlike the Cobra units it does not float. Drop it off a dock and IP68 helps only if you can reach it. Against the marine picks, it gives up NOAA-first channel layouts.

Pros:

• Only IP68-rated pick in this group
• Lightest ham body at 0.65 lb
• USB-C charging, no proprietary dock
• Longest published standby, 75 hours
• 2-year body warranty, the longest ham coverage here

Cons:

• Requires an amateur radio licence
• Does not float if dropped in water
• Only one seller lists it
• Marine channel workflow is less turnkey than the VHF picks

2. TIDRADIO TD-H9 GPS/APRS 10W GMRS Radio Handheld — Runner-up

The TD-H9 is the most feature-dense radio here, with GPS, APRS, and text messaging, but it publishes no waterproof rating.

Best for: buyers who want GPS, APRS and text messaging in one handheld Skip it if: you need a published waterproof rating

If you rank features over sealing, the TD-H9 is the pick. TIDRADIO lists GPS that shares your location for rescue, APRS, NOAA weather monitoring, and an SMS text function for quiet or private messages. It also lists a three-in-one model that switches between ham, GMRS, and unlocked modes, plus Bluetooth programming and VOX. That's a wide toolkit for one handheld.

The maker rates it at 10W, the highest power figure in this set, and lists spectrum analysis on the sheet. The listed weight of 25 g reads as an accessory figure rather than the full radio, so treat it with caution. This is the second-cheapest pick here.

Here's the catch, and it's the reason this is a runner-up and not the winner in a waterproof roundup: there is no stated waterproof standard in the data. For a category defined by sealing, that's a real gap. The warranty is also the shortest at 60 days.

Pros:

• Highest listed power at 10W
• GPS, APRS, and SMS text in one body
• Switches between ham, GMRS, and unlocked modes
• Bluetooth programming supported
• Second-cheapest pick in this group

Cons:

• No published waterproof rating
• Shortest warranty at 60 days
• Listed weight looks like an accessory spec, not the radio
• Only one seller lists it

3. Uniden MHS75 Waterproof Handheld 2-Way VHF Marine radio — Best for pros

The MHS75 is the proven submersible marine VHF here, with a JIS8 rating and full USA, International, and Canadian channels.

Best for: boaters who want a proven submersible VHF with triple watch Skip it if: you want the lightest radio in your pocket

The MHS75 is the seasoned option. Uniden lists a JIS8 waterproof level, a marine submersion standard, and says the radio shrugs off whitecap splash and spray. It covers all USA, International, and Canadian marine channels plus all NOAA weather channels with alert, so a boater who crosses borders is covered.

Power is switchable across 1, 2.5, and 5 watts, which lets you conserve battery for close-in traffic and reach out when you need range. Triple Watch monitors channels 16 and 9 while you listen to your active channel, a genuine safety feature in busy water. The 3-year warranty ties for the longest here.

The knock is bulk. At 1.35 lb it's the heaviest pick, more than twice the RA89's 0.65 lb, and its listed dimensions of 3.4 x 6.4 x 6.2 in read chunky for a handheld. It also dates back to a 2009 release, so it lacks the GPS and text tricks of the TD-H9. What it offers instead is a track record.

Pros:

• JIS8 submersible marine rating
• All USA, International, and Canada channels
• Triple Watch on channels 16 and 9
• 3-year warranty, tied for longest here
• Switchable 1/2.5/5W power

Cons:

• Heaviest pick at 1.35 lb
• Oldest design, 2009 release
• No GPS, APRS, or text features
• Bulky dimensions for a handheld

4. Cobra BlueBound 350 VHF Handheld Marine Radio (Black) — Best minimal setup

The BlueBound 350 floats, which no other radio here does, and keeps operation simple with tri-watch and NOAA alerts.

Best for: new boaters who want a floating VHF that just works Skip it if: you want a keypad and dual-band ham use

Drop this one overboard and it comes back to you. Cobra says the BlueBound 350 has a high-visibility orange floating core for buoyancy and easy retrieval, which is the single most useful trait a handheld can have on open water. That's the reason it earns a spot despite no listed ingress rating.

It's light at 0.59 lb, the lightest here, and Cobra lists 6-watt VHF power switchable across 1, 3, and 6 watts. A Day/Night selectable LCD keeps the screen readable in any light, Tri-Watch covers channels 9, 16, and one of your choice, and there's access to 12 NOAA weather channels. Simple, marine-focused, and hard to fumble.

The compromise is scope. This is a marine VHF only, so it can't do ham or GMRS work, and there's no published submersion rating the way the Uniden lists JIS8. It's also the more expensive of the two Cobra colours by a small margin and sells slightly faster than the white shell.

Pros:

• Floats with a high-visibility core
• Lightest pick at 0.59 lb
• Tri-Watch on channels 9 and 16
• Day/Night selectable display
• 3-year warranty

Cons:

• No published ingress rating
• Marine VHF only, no ham or GMRS
• No keypad frequency entry
• Only one seller lists it

5. Cobra BlueBound 350 VHF Handheld Marine Radio (White) — Best premium

The white BlueBound 350 is the identical floating VHF in a lighter shell, and it's the most expensive pick here.

Best for: boaters who want the floating Cobra in a high-visibility white shell Skip it if: colour makes no difference to you

Everything true of the black BlueBound 350 is true here. Same floating orange core, same 0.59 lb weight, same 6-watt VHF power switchable across 1, 3, and 6 watts, same Tri-Watch and 12 NOAA weather channels, same 3-year warranty. Cobra changed the shell colour to white and nothing else in the published data.

So why the premium label? This is the most expensive pick of the five and carries a slightly higher price position than the black version. Several sellers stock it, which is a small edge over the single-seller listings elsewhere in this group. If a white radio matches your helm or you simply prefer the look, this is the buy.

The honest trade-off is that you pay more for a cosmetic change. There's no extra published capability over the black unit, and like its twin it lists no ingress rating and no ham or GMRS ability. Pick it for the colour, not for performance.

Pros:

• Floats with a high-visibility core
• Same 6W VHF power and Tri-Watch
• Light at 0.59 lb
• 3-year warranty
• Several sellers stock it

Cons:

• Most expensive pick here
• No capability gain over the black version
• No published ingress rating
• Marine VHF only

What does the waterproof rating really promise?

A waterproof rating is a promise about water and dust, and the standards here are not the same. Knowing what each one covers keeps you from trusting a spec that doesn't apply to your use.

• IP68, on the Retevis RA89, is the highest common ingress rating. The 6 means dust-tight; the 8 means it survives continuous submersion beyond one metre, to a depth the maker sets.
• JIS8, on the Uniden MHS75, is a Japanese marine submersion standard that maps closely to IPX8. Uniden calls it submersible.
• "Floats", on both Cobra units, is buoyancy, not a sealing grade. A radio can float and still take on water if a seal fails, so buoyancy and ingress protection are separate promises.
• No rating listed, on the TIDRADIO TD-H9, means you should treat it as splash-risky until the maker states otherwise.

The keyword here is waterproof, and Amazon's search stretches that word across radios that meet very different standards. That's why this best waterproof handheld ham radio comparison ranks the RA89 first: it's the only one with a full IP68 claim in the data. Read the rating, not the marketing word above it.

When a different pick wins

The RA89 is the default, but three concrete conditions flip the decision. Check yourself against these before you buy.

1. If you'll be on the water: a marine VHF wins over a ham handheld. The Uniden MHS75 is the pick, with its JIS8 submersion rating and full channel coverage. On a boat, a ham radio is the wrong tool.
2. If you might drop it overboard: buoyancy beats sealing. Either Cobra BlueBound 350 floats back to you, which no other pick does. A sealed radio at the bottom of a lake is useless.
3. If you want GPS and text in one body: the TIDRADIO TD-H9 carries GPS, APRS, and SMS text, none of which the others list. Just accept there's no stated waterproof rating.

The verdict

If you want the strongest seal on land, buy the Retevis RA89. It's the only pick here with a full IP68 claim, it's light at 0.65 lb, and it charges over USB-C with a 2-year body warranty. For a licensed ham who wants a rugged dual-band handheld, nothing else in this group matches that combination, and that's why it's the best waterproof handheld ham radio for most buyers on shore.

If you'll be on the water, buy the Uniden MHS75 instead. Its JIS8 submersion rating is the second-strongest sealing claim here, it covers all USA, International, and Canadian channels, and Triple Watch keeps channels 16 and 9 live for safety. The cutoff is simple: land versus water. Below the waterline, marine VHF wins on channels and buoyancy; above it, the RA89 wins on sealing and licence-free frequency range.

The runner-up TD-H9's exact advantage is breadth. It packs GPS, APRS, 10W power, and text messaging into one body, more features than any other pick. It loses only because it publishes no waterproof rating, and in a waterproof roundup that's the one thing you can't skip.

FAQ

Is a waterproof handheld ham radio worth it over a standard model?

A waterproof handheld ham radio is worth the extra cost if you use it outdoors in rain, spray, or dust. The Retevis RA89's IP68 claim means dust-tight sealing and submersion protection, which a standard radio lacks. For dry indoor use, the sealing adds nothing you'll notice, so match the rating to your conditions.

What waterproof rating should a handheld radio have?

A waterproof rating on a handheld should be IP67 or higher for real submersion protection. The Retevis RA89 lists IP68, the strongest here, and the Uniden MHS75 lists JIS8, a marine submersion standard close to IPX8. "Water-resistant" or "floats" alone is weaker. Read the standard, not the marketing word, before you rely on it near water.

Is the Retevis RA89 or Uniden MHS75 better for boating?

For boating, the Uniden MHS75 beats the Retevis RA89. It's a marine VHF with all USA, International, and Canadian channels, NOAA weather alerts, and a JIS8 submersion rating. The RA89 is a ham radio and lacks the marine channel layout boaters need. On the water, the MHS75 is the right tool despite weighing 1.35 lb.

Do these waterproof handheld radios float if dropped in water?

Only the Cobra BlueBound 350 pair floats if dropped. Cobra lists a high-visibility orange floating core for buoyancy and retrieval. The Retevis RA89 is IP68-sealed but will sink, and the Uniden MHS75 is submersible but not buoyant. If you boat or fish, buoyancy matters as much as sealing, so weigh both traits.

What is the biggest mistake buyers make with waterproof radios?

The biggest mistake buyers make is comparing wattage instead of the sealing standard. A 10W radio like the TIDRADIO TD-H9 looks powerful, but it lists no waterproof rating at all. Power means nothing if water kills the radio. Check the ingress rating first, then the service type, then power, in that order.

Start by answering one question: land or water? On land with an amateur licence, the Retevis RA89 is the clean default, because its IP68 seal is the strongest promise in this group and it weighs just 0.65 lb. On the water, the Uniden MHS75 or a floating Cobra makes more sense. The RA89 earns the top spot not because it's the most powerful radio here, but because it does the one thing this category is named for better than anything else on the list: it keeps the water out.
