I use one with a beep and a shock. One side of remote beeps then shocks the other side just beeps. It has power settings to give you differant powerd shocks and I test it on my self before dog.After a couple shocks the beeb is all I need, it does not takes long to get results.
I think I use the same one as you. Mine has beep, vibrate, shock and a light.
I beeped didn't work, vibrate didn't work, shocked at 75% and bang did the job lol. Used to be dead against shocking them but it's the only thing that's worked. Now he knows if the collars on he may not bark so he's quiet even with the feel
