Olde field tests the Mac1 turbo

The Mac1 Turbo plus is produced and sold in Florida by Florida American Electronics. This detector was tested in Texas to determine if the mineralization and the iron particles would prohibit it from functioning here. This detector was unlike many of the other detectors that I have used so I was learning all over again how to use the detector correctly. When it arrived at my door we were having our spring high tides and rough surf so it was difficult to find a day when I could get in the water to test it. Finally The day came when the tides subsided some and the big breakers calmed down where I could venture into the water and I was prepared to deal with balancing problems with our beaches here but to my amazement the detector seemed not to be bothered by our beaches and I adjusted it back and forth to set the detector to the beach here and it seemed not to make a lot of difference. Perhaps we are luckier than I thought and our beaches have very little mineralization.

I entered the water using the weighted 10 inch coil and set the threshold to a low tone. At first it seemed strange to me but I noticed after a bit that the detector would go over iron and the signal was clearly discernable as iron. I dug every object that I thought was iron and sure enough it turned out to be iron. This was a big improvement over using the pulse unit here as I have been spending much of my time digging iron and now the Mac1 seemed to work like it was supposed to and I began looking for good targets.

It was early spring and the beaches had been hunted bare in the winter so I knew that very little could be found at this time of year. Before long I got a good signal that really sounded off! I dug down and located a nickle that was about 8 inches deep exactly under the pinpoint spot. Well as loud as the detector whooped when I found the nickle I knew right then it would find gold very deep. The detector seemed very sensitive and before long I started finding quarters. Boy! this thing was fun. It would find quarters very deep and sound off very loud and clear. I found one quarter two shovels deep in the edge of the water and that is deep for any detector. I also tested it on my buried silver quarter in the back yard and was pleased to see that it not only picked up loud and clear but I could hold the coil about five inches over the ground and it would still pick it up good. The coin is buried at a measured seven inches. While I returned several times to the beach looking for better conditions I was largely disappointed in the rough surf and could not go out deeper. I recovered a number of good coins and one silver ring. By the way, you should have heard it whoop when the coil was moved over the silver ring!

At times when I was hunting the water I was sure that I could tell the sound of a pulltab as slightly different than coins. Every time I tested my hunch I was correct and I wish that I had been able to test the detector in the productive summer to see how much gold I could find.

I took a gold ring at the waters edge and buried it at ten inches and was able to pick it up with the detector. I also took a half dollar and buried it a foot deep and it picked it up fine. The ten inch weghted coil seemed just a little difficult for me to manage in the surf but I am a little guy and I don’t think anyone else would have a problem. I also noted that the sound was somewhat loud for my ears so I cut out pieces of sponge and placed them in the earphone recesses which greatly improved the problem that I had with the sound setting. One thing that I might mention. If you are fortunate enough to use one of these fine machines please do not put the earphones on your head and then turn on the detector as the sound made by charging the capacitor will be far too loud for your ears. Once this has charged and stabilized then put on the earphones and set the threshold to the low tone.

My overall impression was positive and I enjoyed moving over the iron targets that I would have dug with my pulse machine and realizing I was saving a lot of time using this detector. The detector has an internal rechargeable nicad battery in a waterproof box. The marine balance is a single turn precision potentiometer and the threshold audio pitch is 200 hrz. The transmit power is 18vac at 14k hertz.

The MAC 1 Turbo Is a very stable single phase three coil detector, it operates in the one foot depth range has tone ID (in the effect) a ferrous target (iron) gives a bong response and a nonferrous target (gold) gives a whoop sound, by not nulling or blanking on iron makes it possible to hear a pieces of gold on top of a piece on iron in salt water no other detector can do that. The salt water effects on the electronics of the detector are completely eliminated so the threshold is very smooth and stable which makes it possible to find the smallest targets.
