Makro Racer and US coins

Someone told me that the Makro will never be hot on US coins because it's calibrated for European coins, unlike detectors from US manufacturers. I know the alloys of coins from different countries does vary so it makes a kind of sense, but have never heard any solid technical discussion of this topic. Just wondered if anyone had heard that or had any further insight into it.

Don't know where you heard the Makros aren't hot on U.S. coins.-----My Racer 2's hit U.S. coins hard & deep, seperates in iron like a dream to with small coil on board.----What's not to like??------Was it a U.S. manufacturer dealer telling you this? (perhaps pushing what he had to sell)

I personally don't believe it since my Racer 2 hits very hard on US coins IMO. But there were some know-it-alls in one of the Facebook groups saying that. I've seen it from time to time on different forums as well.

Scott, there are good reasons why I never do

Remember that visual Target ID got started here in the gold old :usaflag: back in 1983 when George Payne designed the then-new Teknetics CoinComputer 9000 and 8500 models. He then added Tone ID to the mix with their 'B' version upgrade. Back then we had more-or-less a segment or coin name reference for USA coins and other countries had to learn to adapt to what we called a Penny, Nickel, Dime, Quarter, Half and Dollar.

Within a short time we had noteworthy advances in TID technology to incorporate the VDI (Visual Discrimination Indicator) numeric reference, and that worked much better for everyone in every country. At least it works well for those of us in the countries that use a more noble metal in our coins. Once it was 90% silver for when we now call 'clad' with the sandwiched copper core. Out nickels (the 5¢ coins) are still made as they have been for the bulk of their duration, and the cents / pennies have gone from 95% Copper to Zinc with a copper wash.

Not necessarily the best metal comparison, but all of what we use here in the USA is more of a noble, durable metal as they are non-magnetic metals in nature. So many foreign countries, such as Canada to our North, use Steel, Nickel, and other magnetic-based metals, as do many foreign countries in their current or more recent coinage. That makes TID more challenging as the VDI numeric read-out can be more prone to instability, spanning a broader VDI range, and edge-pass sweeps generally reject those types of coins and produce a ferrous or iron audio tone and visual displayed report.

So in conclusion, countries with non-ferrous metals used to make their coins like here in the US are going to be able to have a more consistent and more reliable visual TID response. It doesn't matter if it Is an American coin or one from another country made of a good, non-ferrous metal, they will respond with a tighter, more consistent TID. All the operator needs to do is learn what numeric read-out their coins produce. The Makro Racer 2, its earlier sibling the 'original' Racer, and the sister company, Nokta's, CoRe, Relic and Impact are all excellent detectors that perform exceptionally well and give us very decent lock-on numeric TID's.

Most detector makers today have eliminated any named-coin reference, such as Nickel, Penny, Dime, etc., and have relied on the simple and efficient numeric read-out because that form of VDI is universal to all countries and any coinage.

As always, Monte, thank you for your input.

I might be showing my electronics ignorance here, but is it part of the process (or even possible) to "tune" or "calibrate" detectors to the metallic characteristics of a certain set of coins? I'm thinking along the lines of old Roman coins vs. old US coins, etc. I know that old European coins have been made up of different metal alloys over the years, and European manufacturers might quite naturally design their equipment for those metals. Quite possibly I'm overthinking it (which would not be rare for me...).

And I know what you mean about social media sites. Some of them are so biased toward one detector or another--as in if you're not swinging an E-Trac you don't know what you're doing.

A practice I used on all my detectors, even the ones without tid is to test it with the target to see where it rings in.
The issue with this is you need one to test.
But where forums like this come in is others can post where their machines rang in on certain targets so you'll know.

But I agree with Monte and companies getting away from coin denominations as target IDs because with our world getting smaller many people around the world use the same detectors and having the screen say penny and nickel doesn't help others in other countries

I agree with Stoofs, "test the targets", air tests and in ground.

My Red Racer and Deleon both give consistent tid numbers, on different coils. EXCEPT: Nickels. Nickel numbers can vary by 3 or more, up or down . This has happened on my new 7" concentric coils, on both detectors.

Even the "old antiquated" original Red Racer, like I happily own, is a killer on US coins. Hugely accurate vid.

Might have been luck, but used a Red Racer at beach (Ocean City, NJ) back in August 2017 and we did very well on finding US coins. We left in all metal mode so we could clean up beach as well!!

My daughter was using and this was the first time she could see results. She loved it. So good I might buy another one. Yes, it is 'old' technology, but it done worked good!

Very happy with the Red Racer on US coins.

I have had very good " luck" results with the Red Racer. The Red Racer has found me some very nice old coins and artifacts. Still use one today. Great lil machine. Put a small coil on Red and hit the iron dense sites.......will still run circles around most machines.

I pulled out a 1898 V nickel, in an area that I had been over with my XP Deus. No VDI #, but a good consistent soft tone. About 8 inches deep. Using a Red Racer. I have only had the Racer out a few times, but it locks in on coins.

Inho, hard to beat a Red Racer, for Jewelry and coins. The Deleon is right there with it, especially for simplicity. It's a lot of fun using both of these superb machines.

As noted by Monte, detecting modern cladded coins is particularly challenging in Canada where the coins are generally 95% steel. For me, I have had to listen for both the low tone and the high hiccup which is now indicative of a modern coin. US coins generally come up in a specific TID but modern Canadian...I have pulled my hair before I started to get the sound it makes.

Gregg, while I love the small coil you write of, I love the new 7" concentric even more.

I really like the 7" coil as well...great coil and can handle a good amount of iron etc. But for the worst of it I like the little coils.

As a matter of fact I just got home from a quick hunt with the R2 at one of our tot lots that has been hit hard for years. Take note of the color of the coins. Especially the two nickles. All were pulled below 8" of wood chips and in the mud below. All missed by every other detector that had been over the same spot until the R2 came thru.





The real treasure is in the hunt...
