The Uniden GMR1838-2CK handie talkie offers an extensive list of features (including an emergency weather alert) that will make your afternoon hiking trip, cross country road trip, or family outing to the amusement park much more enjoyable and possibly even safer. Imagine this: It's a sunny morning and you decide to take the family on a hiking day trip. The weather report looks good as you head up the mountain. A few hours into the trip you notice a few clouds off in the distance, but think nothing of it – until your walkie talkie emergency weather alert goes off. Since you didn't pack for an unexpected rash of bad weather, you grab the family and head back to the car. As you reach the end of your hike, a downpour hits. You are so thankful you chose the walkie talkie with the emergency weather alert.

The GMR1838-2CK comes equipped with 22 different channels and also offers 99 different privacy codes, making it much easier to find a channel free from other's conversations. Be aware, however, the Federal Communications Commission requires that you be licensed to use some channels, specifically those labeled as the General Mobile Radio Service (GMRS). This cuts down the number of channels that anyone one can use, known as the Family Radio Service (FRS), to approximately seven. This device is also equipped with auto channel scan which will search for the clearest channel that is available. This can save you time because you won't have to test out each different channel before finding one that will broadcast clearly.

This is an added bonus for those who may be camping and do not have access to an electrical outlet in order to re-charge the walkie talkies. The estimated battery life is approximately 12 hours with low usage. This is for both the NiMH rechargeable battery pack as well as the 4 AAA batteries. Battery life will definitely decrease with the amount of use. In order to be prepared, plan to have at least one set of AAA batteries on hand for each unit.
