The Topcom Twintalker 9100 lets you communicate via 8 channels and 121 sub-channels without needing a permit. Thanks to the integrated channel scan function, the Twintalker 9100 automatically finds the channel that has the best reception for you. The walkie-talkie also has noise suppression for crystal-clear reception. The lighted display shows things such as channel, sub-channel, and frequency. It also shows the battery status, which can be charged using the included desktop charger. Thanks to the IPX2 certification, this walkie-talkie is splash proof, and it can be used in the rain without any problems.
