The Golden µMax is getting a new and improved tone change, starting with serial number: 190900. The manual will have "Rev 2.0" on the front. All Golden µMax detectors that are currently being shipped have this change.
Some Customers had difficulties separating the tones, so we separated them further. By changing the pitches, we have made it easier to identify all 4 tones clearly, making it easier to identify targets.
The order of the has also changed...with lower tones to identify potential trash, and higher tones reflecting valuable targets like silver and nickels. See the chart below.
| New Tones, Conductivity Range | |
|---|---|
| Ferrous/Iron/Foil | Low |
| Nickel | Medium High |
| Pull Tab/Zinc Penny | Medium Low |
| Silver | High |
| Old Tones, Conductivity Range | |
|---|---|
| Ferrous/Iron/Foil | Low |
| Nickel | Medium Low |
| Pull Tab/Zinc Penny | Medium High |
| Silver | High |
The notch-width control must be adjusted while air testing a nickel with the discriminate control turned completely down to "min". With the notch switch in eitherwide or narrow position, adjust the notch-width to obtain a good target sound on nickel. This will give you four target tones. If the notch-width is NOT set correctly, you will only hear three tones. This is the correct way to setup a Golden µMax, regardless of whether it has the new or the older version.
If you have a NEW (still in the box) Golden µMax detector, you can have the tones changed for $25.00. If your detector is USED, the tone change will cost $50.00.

The µMax detector that you have been waiting for is here - The Golden µMax. This is a detector that only Tesoro could build. Full size depth, sensitivity, Four Tone Audio ID and a user adjustable Notch Filter Discriminate all placed into the lightest detector housing on the market. At less than 2 ½ pounds, the Golden µMax lets you control what you want to find. Our adjustable notch window lets you, not the engineers, decide how to pick through the pull tabs to find the nickels and gold rings, while the ED 120 discrimination knocks out all of the nasty iron. The tone ID will also give you a great idea of what your target is. The Golden µMax will help you define your targets and make better use of your detecting time.
