Review: How to use this tester. - It worked well. The instructions were not helpful. Quick breakdown of how to use this: 1: Take what looks like a white clored pencil (cleaner) and rub it on the surfaces where the alligator clip comes in contact and where you intend to touch the test piece to the machine. 2: there is a liquid that comes with this machine in a small dropper. Fill up the cound test area on the machine to create a small puddle (about 3 to 4 drops) 3: press the button that corresponds with the type of gold being tested. Once the machine lights up wait untill the lights on the carot indicator go dark. 4: place the part of the gold test piece you cleaned earlier to the little puddle of solution in the test area and hold it there. If it's real gold, the test light will flash or be solid for a brief moment, then the corresponding carot light will show. If it's not gold the red "not gold" light will light up. Hope this helps.
Review: Garage - Didn’t work!!! What if way too long for a machine that could be considered to me accurate in these time. Garage and some how making me pay for rerun shipping? Haha wrong person!

## Questions & Answers

**Q: Does the solution leave a mark on the gold?  Thanks for your help.**
A: It does not on real gold, however when testing plated or other metals it will, hope that helps

**Q: Does this come with the solution?**
A: It depends on where you buy it.  The solution is getting more expensive lately.  It used to be less than $20 and now it is close to $27.

**Q: Can you test gold bullion and coins with this**
A: Yes both can be tested with the M24, I no longer own my M24 as I sold it and purchased a KEE Gold Tester, check them out as I believe you will like the KEE Gold Tester over the M24 as I prefer it 10 to 1 over the M24.Regards,Terry L. Shookof Carolina Coins and Detectors

**Q: What kind of battery?**
A: I bought for a friend. I have the ET18 it uses 9V battery. So maybe this is the same.

### ⭐⭐⭐⭐ Couldn’t figure out how to get a true reading
*by J***E on November 25, 2023*

It seemed as though my tests could not get accurate reading. I think the machine is probably a high quality machine. I think the issue was my own lack of knowledge on using this device.
