Are the seniors specific? I don't see any markings indicated one is for low level and one is for high

I think all the logic is done in the controller in the plug unit. It arms when either sensor is submerged and activates when the other submerges. The pump then stops when the water level drops below both sensors.

These sensors are not specific for high/low position. Either way it will work to the best performance. Works great for me.

You can use either or, but they do appear to have a memory once you start using them.

I noticed that too. I installed them and figured 50/50 chance - got them right on the first time. You can also install in a bucket to test with a voltmeter or some electrical device plugged into the socket to determine when power is there.

As far as I now there is no difference. I have changed mine for different water levels a couple of times. paid no attention to which is which, and everything always worked.

There is a card that comes with it to explain the different levels. I hope this helps...

Hey Katie! There should be a card with "norms" on it for various ages and genders. You can use those numbers to let them know if they need to strengthen or if they are at or above average!

I'm under the assumption that they're the same, just different numbers. I believe this is the newer one.

Separate for low and high can't change level of either but they are set very well

I had to turn it on and check, good question. It is one for low, two for medium and three for high.

Truthfully, I don't know. I'm a senior and my son does things like that for me. I'm sure someone else will have the answer. Sorry.

Actually there are markings, they are just verrrry hard to see. There is a sloped edge where the batteries go in and if you get the light just right you can see the + or - signs.

So far I can't tell a difference. But I have always been very active before I purchased one. I got one for my Mother and she swears by it. She is 73!

Maybe Dennis is a senior, or maybe he is just helping a senior with the selection. I am trying to find something for my parents, who are 80-ish. They had a computer a while back for word processing, but have never gone online. I know they would love it if they had a very user-friendly machine. Dennis, did you find something good? I'd love to know.

It does not ship with a level indicator. They can be purchased separately. I didn't get the indicator so I can't speak to its quality or effectiveness.

There may be two different versions. The ones I purchased DID NOT have graduations marked on the side. For my purpose, they were not needed, so for me, it was irrelevant whether they had markings on the side. If the markings are important for this purpose, and I assume they must be if you are asking this question, you should contact the individual seller to confirm. Just click on the sellers name, which takes you to their website, then click on Contact Seller. Better to ask BEFORE you buy. Ask several of the sellers for this item whether their specific product has markings.

The older ones were. I had to replace mine and low and behold it says USA on it. So I guess the answer is USA.
