The black receiver is not like the old version or any imitators with fixed mode of vibration and shock. The new bone will deliver vibration/shock truly under your control. If the button is pushed once, the receiver will vibrate or shock once, not three or four times in a row. The intensity of the low level(L1 or L2) is TRULY low level shock(NOTE: other competitors' low shock is NOT LOW, is very powerful and is the same level as HIGH.Just the high level repeats 3 times of the "low" shock).
Our product delivers the true low shock is for small dogs or sensitive dogs while the high level with noticeably more powerful jolt for a large dog or more headstrong/insensitive dogs.
This 300 meter range remote control dog training shock collar system has shock and vibration corrections for each dog. This collar has the most intuitive operation and simplest button layout for fast access and instant control of your dog's unwanted behaviors such as excessive or aggressive barking or or chasing cars or for obedience training. This collar has 3 vibration command buttons:V1 for dog 1, V2 for dog 2 and V for both dogs. This two vibration setting will serve different training purposes. For example,V1,V2 serve as warning before shock and V as attention call for two dogs . This is to make your training easier yet more efficient.
