Note:
It is best not to deliberately tease the dog with the dog drive, because it is not surprising that the dog listens more. When the light in the dog drive is obviously dim, replace the battery in time.
 The effect is better when using alkaline batteries. After a comparative test with special instruments, the ultrasonic output power and efficiency of this product have been the best among similar products. Due to the current power limitation of the ultrasonic head, if the output power is further provided, the ultrasonic head will be damaged quickly. Only in the future will a high-power ultrasonic head be developed (there is no higher ultrasonic transmitting head before the world).
