You can easily communicate up to a distance of 7 kilometers, using the Alecto FR-10. You can choose between 8 frequency channels, so there's always a free channel for uninterrupted communication. The walkie-talkies will scan for the most suitable frequency themselves, thanks to their channel scan function. The walkie-talkies need to be recharged after 3 hours of talking. The battery level is shown on the illuminated screen, so that you'll promptly know when the FR-10 is out of power. Don't want to hold the devices continuously? Simply use the included belt clamps.
