The UNIDEN GMR5089 is robust, durable, and waterproof. It boasts a huge maximum range of 50 miles, and is bursting with features. Add this four pack of two-way radios to your outdoor gear or emergency kit, be prepared for any eventuality, and stay in contact with your team members at all times. It doesn’t matter if you’re hunting, hiking, participating in extreme sports or survival exercises, or getting prepared for real emergencies, the GMR5089 four pack is an essential piece of outdoor gear.
Here’s what’s in the box:

  • 4 Uniden GMR5089 radios
  • 4 NiMH rechargeable battery packs
  • 1 multi-radio charging station
  • 4 headsets
  • 4 carabiner belt clips

Stay in Contact

The Uniden GMR5089 is a smart choice for both long and short range communication. You’ve got 7 FRS channels with a maximum range of around 5 miles for clear, crisp short-range communication. For long range contact, you’ve got 15 GMRS channels, with a maximum range of 18 miles. This range increases to an impressive 50 miles when these channels are used in conjunction with the boost feature.

No Eavesdropping

As well as the 22 possible open channels, the GMR5089 from Uniden offers 142 privacy codes, giving you a huge number of potential combinations, so you can easily find an empty channel.
If you want even more privacy, simply activate Group Mode. If your whole community has radios with Group Mode functionality, you can converse privately, without worrying about eavesdropping.
For those times when you need to talk one-on-one with a member of your group, use Direct Call. Choose the four letter string of the user you want to call, and their radio emits a call tone, just like a cellphone. Then you can talk in absolute privacy.
And, when you want to listen into your group’s channel, but you don’t want lots of noise, simply plug in your included headset, complete with mic, and listen (and talk) away, without being overheard and without disturbing the wildlife.


When you’re near water and your two-way slips through your fingers, that “splash” fills you with dismay. But with the GMR5089, you don’t have to worry. It’s waterproof. In fact, it’s even better than that – it’s submersible up to 3 feet for 30 minutes. But wait – it gets better. Let’s face it, if you’re in open water and drop your two-way in, even if it’s waterproof, it’ll be lost beneath the water – you’re not too likely to jump in and find it – but if you drop the this Uniden two-way, it bobs back to the surface. That’s right – it floats! So you can just scoop it off the surface.

Light it Up

So you’re camping and you need to answer a call of nature. Or perhaps there’s a power outage and you need to go fire up your backup generator. But it’s dark. As long as you’ve got your Uniden close by, it’s all good. The radio features a high-intensity LED flashlight. And, if you need assistance, you can set the light to flash S.O.S in international Morse Code.

Get the Latest Forecasts

7 NOAA weather channels allow you to stay up to date with all the latest weather conditions and get prioritized alerts if the radio detects a warning in your area.

Long Battery Life

With the rechargeable NiMH battery pack, you can expect around 10 hours of battery life on average. It’s easy to recharge, as it comes with a charging cradle and cable that you simply plug into an outlet.

More About Uniden GMR5089-2CKHS Submersible Two-Way Radio FRS/GMRS Walkie Talkie 4 PACK

The Uniden GMR5089 four pack is an all purpose two-way radio system meant for individuals looking for a rugged but easy-to-carry device for camping or emergency situations. This radio set is also perfect for people going on boating trips, because of the durability of the design and the inclusion of waterproofing. Everything you could want and/or need with a two way radio set is included in this package for an affordable price. No need to make extra purchases for headsets or accessories either, they come with the bundle.

The maximum range for the Uniden GMR5089 is 50 miles. For channels 1-7 and channels 15-22, the maximum range is 18 miles. With the use of the boost function, however, those two ranges expand to the full 50. Channels 8-14, the FRS channels, have a maximum range of around 5 miles (the boost function is not utilized by the FRS channels).

The radios come with rechargeable NiMH battery packs (with a 5/5/90 duty cycle) which are recharged using the charging cradle (included). The average battery life for these batteries is around 10 hours, assuming the boost function is not being used. It should be noted, however, that this radio set does not accept loose batteries as some radios do. This is because of the inherent design of the unit.

This radio system includes 22 possible operating channels. Six of those channels (8-14) are FRS channels. The others are all GMRS channels, meant for longer range communications. There are also 7 NOAA weather channels which are included. These weather channels are extremely useful in keeping you up to date on changes in the weather or for emergency communications which may be taking place. With the addition of the 38 sub-audible tons and 104 DCS codes, the functionality of these radios for private communications is expanded even further.

Due to the way these radios were designed, they are able to float on water. Better still, they can be submerged for up to 3 meters for a time limit of up to 30 minutes before sustaining any serious damage. With the included rubber seals and the jack cover, you never have to worry about water leaking on.

The GMR5089 also includes an emergency strobe functionality. On the face of the unit is a small LED which can be activated when necessary and which will function as a strobe during emergency situations or to alert others to your location.

This radio set also comes with a standard 3 year warranty from Uniden. If there are any inherent flaws or functional damage resulting from the design of the units, Uniden will either fix or replace the units at no charge to you for up to 3 years. Just keep your purchase information. This warranty is void if the units are modified or programmed by anyone besides a qualified Uniden employee.

Regardless of your needs for a two way radio set, the GMR5089 is a great choice. Given the additional functionality without an added cost, it is great for a variety of situations. Better yet, the fact that the radios are submersible in up to 3 feet of water with no damage (and float) means you won’t have to worry about them falling overboard and getting lost on your next boating trip either. The GMR 5089 is a great choice, especially at the price point it is listed at, and it is a be-all end-all radio for individuals who are on the market looking for one.
