SpraySense Anti-Bark Collar quickly conditions dogs to stop unwanted barking. • Harmless burst of spray distracts the dog and effectively redirects behavior without painful consequences. • Clinically proven 2x more effective than shock. • Improved durability and reliability…better quality, vibration-resistant, high-impact nylon casing; better performing electronic components. • New microphone that more effectively filters ambient noise for fewer ‘false’ sprays. • Longer battery life…a more efficient spray mechanism operates at a lower voltage thereby extending battery life an average of 35%. • Rigorous testing to guarantee optimal performance… successful completion of >80,000 cycles (the equivalent of 5 years actual use) and proven real-life reliability of all production runs to date (more than 10,000 units). • Fewer defects…higher quality components and stringent QC testing has reduced out-of-the-box failure to <1% and in-the-field failure to <2%.
