Delta 4000 tips
- Thread starter prodrigsr

Before the 'tips' let me just clarify that many will apply to most of the two-filter type, slow-motion detectors, but not all slow-sweep designs are also a "quick-response" design. Some, like most Garrett's, White's Prizm and Coinmaster (current) models, and some others have a delayed response. Models such as Tesoro's, White's Classic's, M6 and MXT's and ALL Teknetics models and many newer Fisher designs have a very quick-response design.
I state this because there will be times we hunt areas that are trashy enough that it is difficult to use a threshold-based All Metal Pinpoint function. When conditions are that tough, it is really beneficial to be using a quick-response/fast-recovery model which lets us isolate and pinpoint a target using the silent-search Discriminate mode. I guess that explains why every detector in my current personal arsenal IS a quick-response detector.
Now, a few 'tips' based upon my many years of enjoying these types of detectors:
Tip #1 .. Sweep slowly and methodically.
Tip #2 .. Remember to overlap each sweep and ample amount to provide effective coverage.
Tip #3.. If searching in a dense mineral body environment, such as pea gravel or black sand, etc., do NOT sweep too quickly as it can impair performance.
Tip #4 .. When you encounter a target and wish to use the Target ID (TID) and Visual Discrimination Indicator (VDI) numeric read-out, sweep the search coils center directly across the target, and sweep the coil so each outer edge of the coil is swept past the target. This will provide the best accurate information.
Tip #5 .. Using the numeric indication, look for a tighter span of numbers, usually no more than 2-4 numbers total, to suggest a particular anticipated target (good target sich as a coin or ring), and perhaps be more suspect of a broad-ranging or jumpy numeric readout.
Tip #6 .. Remember, however, that should you be searching a site that is densely littered with trash, especially iron type trash, you can forget Tip #3 and Tip #4 as being highly reliable. Masking trash too close to a desired target will cause both audio response fluctuations or different subtle sounds, and also torque the visual information, too.
Tip #7 .. Often, the 'standard' search coil can work reasonably well for typical hunting conditions, but never under-estimate the benefits of using a smaller-than-stock coil. In the case of using any Teknetics detector, the appropriate 5" DD coil will surprise most people at the depth and all-purpose performance it provides. Smaller coils are excellent for hunting in very brushy sites, close to metal structures, and in heavily littered areas. The Delta, and other quick-response detectors, take advantage of the smaller coil and Double-D design to excel in such challenging environments.
Tip #8 .. Appreciate the value of a good TID and VDI design, but ..... Use caution and employ those tools when necessary. An example might be to rely on a more accurate reading when coin hunting a well manicured lawn so you do less recovery and maybe cause less visible disturbance.
Tip #9 .. Also appreciate the fact that while we have certain know objects of known size, shape and alloy content (US coins), there are far more targets out there that might be desired or might be considered junk, that will produce identical or very similar TID and VDI numeric readings, therefore ......
...... we can't get rid of those ring-type pull tabs or modern rectangular pry tabs that, unfortunately, have VDI numbers that read similar to the US 5
