Whichever person you are, or whatever your need, rest assured that you will be able to buy walkie talkie units which fully address your needs. Here are some examples of the variety out there.
1. The Midland GXT 1000VP4 walkie talkie
These particular waterproof walkie talkies are described as JIS4 waterproof. What this means is that the units are merely protected against light rain or splashing water. So clearly this is not a radio which will take kindly to being submerged in water for periods of time. It offers a greater level of protection than something which isn’t waterproof at all, but the protection is limited. This would be more suited to uses which don’t necessarily involve heavy rain or heavy and constant splashes of water.
2. The Uniden GMR2875-2CK two way radio
This walkie talkie waterproof device is more for the person who really will be using it in places where it won’t just get splashed on, but submerged. It’s described as JIS7 waterproof which means that these radios can be completely immersed in water, and yet they will continue to function normally. It’s pretty obvious that these are meant to be used on or near the water since they actually have a design which allows them to float, if they ever fall into a river, lake or the ocean. These are truly waterproof two way radios.
3. The Motorola FV200AA walkie talkie
This two way radio is advertised as being water-resistant. It’s probably safe to say that you will not want to submerge these devices in water, and that you would probably be better served if you can avoid them getting wet in the first place. They’re pretty simple to operate and cost less than many other models, which makes them viable as devices to have your kids use.
Now these models are presented here, not in order to recommend them instead of their competitors, but just to give a birds eye view of the variety available out there. Again, there are many different two way radios which claim to be waterproof in some way. Be sure to go into the details before you make your purchase. Check if the unit claims to reach a particular standard of waterproof-ness.
If it claims to be water resistant, dig deeper and find out what does it exactly mean. Does this mean you can use it underwater? Or that it can survive a short plunge into water? Or will it stop working if it gets fully submerged? Make sure that the unit will be up to the punishment, if any, that you expect it to undergo, over prolonged use.
