Philippe Dhont, an electrical engineer, has independently and voluntarily written an article about tests he performed investigating the electric signal produced by commonly used electronic collar brands.
In the article, he examines the signal and the quality of the signal and makes a comparison between the brands. Here you can find the Conclusion of the Article.
After analyzing the results of this test, it is clear that there is a big difference in the electrical signal between the vendors. There are several important parameters in e- collar devices. You have the waveform of the signal, the amount of levels you can apply, the power of the device, the width and the duration of the impulses. The combination of those parameters make it a good or a bad device! Having 100 or 127 levels of stim doesn’t mean you have a better e-collar!
E-collar technologies told me that the signal in their products is wide and comparable with a muscle stimulator. Because of what they told me I expected another waveform so I am disappointed in the outcome of the e-collar technologies equipment. For me, the waveform is important and based on what they told me, I bought a PE-900. The PE-900 is not a bad device but the waveform looks like the Dogtra waveform so that difference is too small and it is not what I wanted or expected. I didn’t want to buy a new e-collar just to have the same e-collar in a new jacket. It looks like Martin System has the most sophisticated technology, they are also more expensive but maybe there is a reason for that and that is that quality is something that needs to be paid (For your information, I don’t own a Martin System e-collar –yet-)! If Martin System would have had detailed papers available on their website and a better explanation about their “constant stimulation sensation” (S.S.C.) and their “new high voltage” (N.H.T.), I might have bought the PT-3000 with finger kick. There is also a lot of marketing chit-chat going on about e- collars and it is not always easy to make the right decision because you rely on the explanation, knowledge and experience of somebody else if you want to buy an e-collar. With this report, you have extra information that can help you make a good and wise choice, in favor of your dog. That doesn’t mean that everybody has to buy a particular brand because everybody has his own reasons why he/she should buy a device (good support, looks nice, easy to work with, cheaper, more features, etc...) but remember that if you go cheap, you will end up with crap and that’s not good for the dog or the public opinion about e-collars. As a dog trainer and dog lover, I want to train & rehabilitate dogs and make use of the technology to do so. I trained my shelter pitbull with an e-collar –as a tool in my training plan- and he is doing great.
About the Garmin I have a mixed feeling, it has a real AC waveform in the lower levels but it’s a device with a lot of power so you need to be cautious with sensitive dogs and/or inexperienced handlers. With the Garmin, I like the fact that they have a different waveform without the pinprick in the lower levels but I would like to see a same waveform in the higher levels and with this amount of power it would be better if there were much more levels on that e-collar (like 100) so you can gradually go up. There is also a bark control feature on that e-collar but I wouldn’t use that because for a good bark control device, you have to measure the sound AND the vibrations in the dog’s throat.
There is one e-collar that I would have liked to have too for this test and that is the Chamelon® II. The Chamelon® II, designed by Bart & Michael Bellon has Martin System technology under the hood and is improved with another design. You can charge it via induction, has contact feathers and a bungee collar so you really can’t compare it with any other e-collar.
So finally, if I have to choose a winner based on the waveform and the quality of the signal, it would be Martin System since they can keep that same stable waveform in the different levels without going high in power and they have the most features (PT 3000). Because of the combination of that stable waveform, most sophisticated signal (they change the width and the height of the amplitude) and advanced features, you have the ability to get the best training results with your dog.
If you want to train with an e-collar, buy a quality product and pay a good trainer to help you and keep in mind that the e-collar is only a tool in your training plan. First, you need to understand how you need to communicate with your dog and how you need to treat him to establish a rock-solid relationship. Good luck!"
