I just got mine today. Metal does not seem to play a factor in the detection. It appears to be vibration Does anyone know for sure?

It's definitely metal. I've had mine for 2 years and even carrying a shovel down the driveway will trigger the alarm.

The plastic conduit you bury is simply a coil of wire. When a metal object passes near enough to it, it induces a current which is detected by the black box and a signal is sent to the receiver. So yes, it is metal that sets if off, not vibration. If for your equipment it is vibration setting it off, and waving a metal shovel over the top does nothing, I'd suspect you may have a broken wire someplace.

Mine never worked. You are better off with the Mighty Mule 231 (on Amazon) - I have one for 2 years now, no issues, no false alarms. My buddy also got one - also no issues. Good Luck.

It detects a metal object of sufficient mass. Vibration is not a detection. Could be a loose connection is closing and opening due to the vibration. I returned mine, it seemed cheaply made, worked only sporadically and I was confident it not last.

Unless they have made a MAJOR change, it is definitely metal related. You can test this by passing a sledge hammer or similar metal object close to the sensor pipe. I see another answer mentioned using a shovel.If you have to fuss with juxtaposing the the gray transmitter box and the little white receiver, the hammer is much more convenient than driving you car back and forth. A helper and cell phones is a must unless your hearing is a lot better than mine.

I've used mine well over 100 times and the metal prongs are still solid. Must be defective, I'd send it back

I didn't pay any attention when I installed mine. But it has lots of mineral rocks so I can see whyit would make noise when you shake it.

hello . yes it will certainly detect the ring if it were me i would run the all metal mode first . if the ring is in water dont let the control box get in the water. it must stay dry. not sure about salt water searching though, probably not the best choice for the wet side of the salt water beach . hope this helps and good luck !

HI! it only makes a sound over metal! =-) It is a really great little detector. In time my son (12 years ole and brilliant) LOL does want a more professional one that will actually filter out junk from the good stuff . Those are a few hundred dollars so that will be when he is much older. For now he LOVES this thing and when we bring it to the playground or beach he has a ton of little followers that are intrigued beyond belief. SO far my son has found an old belt buckle (1800's) old medicine bottle (again (1800's era) tons of coins. =-)

The vibration is not bad or bothersome. You will feel a slight vibration on the higher settings.

That happened to me once. I heard what sounded like a diseased bird every few seconds while I was in another room. I remember that I touched the product the previous time I'd washed my hands, but I must have touched on the sensor in such a way that it constantly detected something. Clean off the sensor, and see what happens.

I used them for several weeks and didn't notice much noise. There was some metal tapping sound.

Haven't had that problem. Only thing I can think of other than it is just broken is maybe the batteries are too weak to trigger the vibration feature?

If close enough, it will alert to metallic presence. Not the best choice thou for searching larger areas, as you must be very close to the object you're searching for.

Yes mine did, I was wondering the same thing but after a wile it answered my question. I don't know why or how but I guess once the metal gets carbon on it or something it becomes louder

@ Norma, yes you can feel the vibration. You can also set the intensity of it. 0-100.

Yes. It is very sensitive. I like it, no problems as of yet. I use the vibration without sound alert to save battery life. You can't miss the vibration, you'll feel it.

We went through a scanner without it being set off. I would imagine they are set rather low on the metal detection ranges. That was at a courthouse. That part of it is good. I just don't care for the durability of the plastic clips.

I have not discovered a vibration and neither has my dog. That being said, the "nick" on low power does not cause the dog any noticeable discomfort but doesserve as a warning. I have used the collar for about a month and I seldom have to "stimulate" any more. I would not worry about the pager. This is my secondcollar and it is far superior to the product I attempted to use before. Hope this was helpful.

It's metal of some kind. I just flicked it with my fingernail and it makes a "ding"

You should be able to actually feel it vibrate. To feel the shock you have to touch BOTH tips on your fingers. This is not true with the vibration. You can feel it just by holding it. Send it back but if it is too late to return to Amazon then call the company. I think they have a year warranty. For the little extra money I bought the 2 pack then I always have one charged.
