Pain Relief Devices: TENS 3000 vs. TENS 7000

TENS 3000 Versus TENS 7000

There are a lot of people who are in pain for a variety of different reasons, and who need frequent treatments to deal with said pain. For those who have excellent insurance coverage, getting that pain seen to is usually pretty straightforward, but for those who don’t, pain management sessions can become very expensive indeed. The people who fall into the latter group do have a solution they can turn to, though, which are the TENS units that have been specifically designed to help deal with pain. A search for these units will show that the TENS 3000 and TENS 7000 devices are the most popular, but that raises the question about the differences between the two. Let’s take a closer look.

Programs and Modes

The first major difference between the two units are the number of programs and modes that they offer. The TENS 3000 comes with 3 modes, which are Burst, Constant, and Modulation. There are a pair of dials to adjust the pulse width and pulse rate, and a pair of fixed sessions at 15 and 30 minutes. There are an additional two modes – SD1 and SD2 – with the TENS 7000, as well as greater control over timing, pulse, intensity, and more. In short, the 7000 offers a whole lot more pain relief options than the 3000, which may make it a better option for those with extreme pain issues.

Channels and Intensity Levels

Both units come with two channels, which is handy if you are experiencing more pain on one side of your body than the other. This allows the user to use either Channel 1 with one lead wire and 1-2 electrodes at a time, or both Channel 1 and Channel 2 with two lead wires and up to 4 electrodes at a time. With regards to the power of the units, the TENS 3000 has a pulse amplitude, or intensity level, adjustable from 0-80mA in 10mA increments, which is controlled by the respective knobs located at the top of the device, for both channels. This allows you to set the optimal intensity level of stimulation depending on your level of pain. The TENS 7000 features the exact same type of controls for pulse amplitude but has a greater maximum intensity output at 100mA, instead of 80 like the TENS 3000, which can accommodate the relief of more chronic pain conditions.

Ease of Use

Both machines may look a little complicated at first glance, but both are actually very easy to use. Both units come with a clear, concise user manual that shows you how to adjust all of the main settings and controls. The TENS 3000 is an analog unit, with dials and buttons that may be a little on the small side, but not to the point where they are impossible to adjust, whereas the TENS 7000 is a digital unit where all of the parameters can be viewed through an LCD screen. Both units run on 9V batteries that deliver a pretty long life, and which are also very easy to replace. Both units are highly portable, as they are lightweight, and are a little smaller in size than the average smartphone. The units also come standard with a belt clip for added convenience. That makes them an excellent option for those who want some pain relief when they are on-the-go.


If you shop around a little, you can find both of these units at very affordable prices. The TENS 3000 can be found for under $20, while the 7000 comes in at around $30 or less. Both are exceptionally good pain relief devices, and arguably two of the most popular stand-alone portable TENS units available on the market, both commonly purchased by both end users and doctors/clinics alike. The final purchase decision really does come down to personal choice.

I'm not sure how I could live without. My tens 7000. I've had this device for over 10 years now. First of all the longevity of it impresses me most things give out before 10 years. However this machine has been a lifesaver literally. My friend bought it for me many years ago when I first started experiencing severe back problems. It helps some but then the pain got to the extreme that I couldn't deal with it and had back surgery. I had my tree lower vertebrae fused didn't do a lot of good and even with the use of tens had been a problem until I finally had an electronic stimulator inserted in my back in October. At that point my neck and despite the efforts of my pain Physicians I still suffer a lot of pain. My family lives 7 hours drive away and I cannot drive however this summer I took my first trip home in 3 years and found that by using the tens the trip was comfortable for me and enjoyable. Since then I have been back 3 X. I haven't given myself but I'm going to try that next time. I now carry the tens with me at all times. I've been thinking about getting another unit to carry in the car so if for some reason I forget my unit I will have a spare. Matter fact I purchased another unit with basically the same capabilities however it was much thinner so it was easier to hide under my clothes. Also it was rechargeable. Well it wasn't the same unit I sent it back real fast. It kept turning off in my pocket there was no protection for the buttons. It didn't seem to have the same power intensity either and it had to snap on pads which I didn't like. Live on a fixed income therefore I have to wait a while before I can purchase another one but I will eventually do that. This is the greatest unit going and if you have pain it really works. I can't say enough good about it and I will never buy another one that is not the tens 7000.

I find it so hard to believe that a Ten's Pro would last 10 or has been out for 10 years. I've owned 2 of the 3000, I loved them, but both broke down within months. I've read the Amazon reviews on the 7000, and many people have had the same problem, even if they don't last long I'm purchasing another one due to how well the 3000's I owned were great.

I have two of the TENS 3000 units; bought in 2012. Both are still doing great. They have been spot on tools for the low back problems I have and have worked for wife's shoulder issues. Would not trade for anything.
