No wasted power, no unnecessary disruption to your space. Dual High-Power Emitters - 20m Max Coverage2 High-Power Ultrasonic Heads: Equipped with two large-output ultrasonic emitters (vs. single-head models) - boosts signal strength and expands maximum coverage to 20 meters (75ft). Covers large yards, patios, sidewalks, or apartment complexes, ensuring even distant barking dogs (yours or neighbors') are targeted.3 Adjustable Working Ranges: Choose from 25ft (7.6m), 50ft (15.2m), or 75ft (22.9m) - the higher the range, the more sensitive the device is to barks and the farther it works.
