1. Line of sight is not required
The range is very long, even when there are object or walls blocking the wireless signal. These will reduce the range, but often times not enough for you to notice.

2. The "unlimited" range hack
The Receiver is designed to hang beside the blast pot, but it doesn’t have to! Simply connect your existing deadman cable between the blast pot and the Receiver, then move the Receiver anywhere you’d like. Now you can have all the benefits of wireless blasting, even in the toughest situations

3. Optimize your setup
Range will decrease depending on interference and obstruction. For best results, mount both devices far from the ground or any metal objects and orient them vertically facing each other.

4. Protective enclosures are not necessary
Placing the Receiver in an enclosure is fine, you won't notice much of a change in range, however it is certainly not necessary due to the robust design
