The Pet Life Crescendo LED 5-Level Automated Vibration Sound and Stimulation Anti-Bark Dog Collar features a smart 5-Mode automated anti-bark reaction system or smart triggering mode that methodically delivers 1-3 levels of Beep, Vibration and light-grade Electronic Stimulation. This automated system activates every 30 seconds following the sound of a Bark. This safer alternative to standard E-Shock collars is designed to automate corrective actions while limiting usage for Electronic Stimulation by prioritizing Beeping and Vibration. This device features a battery-saving auto-off mechanism. Battery lasts 10 Days of usage and takes 1-Hour to fully charge. Equipped with a waterproof LED Display Screen with a Durable and Adjustable Nylon collar that fits neck-girths from 6.5 - 24 Inches. Includes a USB Charger with Short and Long-hair contact points. Available in Multiple Colors.

5-Mode Automated Reaction System:
First Mode provides a 1-Level Vibration + Beep (30 Sec pause). Secondary Mode provides 1-Level Beep + 2-Level Vibration + 1 Level Shock (30 Sec Pause).
Third Mode provides a 2-Level Vibration + Sound (30 Sec Pause). Fourth Mode provides a 2-Level Vibration + 2-Level Shock + Beep (30 Sec Pause). Fifth Mode provides 3-Level Shock + 2-Level Vibration + Sound (1 Min Pause). If the device doesn't detect Barking the cycle reverts back to the First Mode.
