      Hi all, 
      Just to change things up from all the Simplex chatter of late, I wanted to share why I still love my Impact, and a few differences compared to some of the other Nokta/Makro units. 
      Multi with 20 kHz. Nokta Makro have had a few machines running at 19 kHz, but for some reason, I can get bad interference around here, not all sites, but usually parks adjacent to houses. To be fair though, Freq shift usually sorts it out (I did run the Fors Gold+ as a shallow coin plucker for a while) but 20 kHz is a little quieter than 19 kHz which is great. Only the Anfibio Multi also offers a 20 kHz option. No real drama on the Multi Kruzer though, as I'd just use 14 kHz anyway for general coin hunting.  
      AA Batteries. While I do like the light weight of the Kruzer/Anfibio with the internal batteries, I don't always remember to recharge them. On the Impact I run rechargeable NiMH batteries, but if I turn it on and the battery bars are telling me it's low, I can just whip in some Alkalines and I'm good to go. Also, having some of the circuitry and batteries right out past the armrest provides excellent balance. Of course this can also be achieved with the optional AA pack for the Kruzer and Anfibio series.
      Now the Racer 2 is lighter than the Impact and balances nicely with the batteries under the armrest, but it's 14 kHz only, and lacks a few features that I like, so don't have one in my personal arsenal. I have thought about getting another R2 and keeping a 7" concentric strapped to the end of it, but I might wait to see what optional coils come out for the Simplex. Oops haha
      DI3/3-tone. 3 tone in the Kruzer and Anfibio series is lightning quick, but sacrifices a bit of depth, unless you get the Sens on 90 or higher. I like that the Impact doesn't have this dual recovery split, it may be a touch slower, but it is still more than fast enough in my sites. I can also set the Sensitivity where it suits the site, and don't have to worry I may be losing depth if the Sens is below 90. The next logical step for Nokta Makro (on their higher end machines at least) would be a user adjustable recovery. 
      Night search light! Again a feature on the Racer series, but not present on the Kruzer and Anfibio line. I do most of my beach searches at night, so having a unit with a built in search light is a real bonus. Another plus to the Impact, and re-introduced on the Simplex, arghhhh I just can't not mention it 😊



      Concealed cable! The only unit in the Nokta/Makro line-up to have a concealed coil cable. Just gives the Impact that sleek look, and also don't have to worry about the cable getting scratched up in scrubby terrain, or accidentally hitting it with my digger!  The draw back though is you can't really interchange coils between the Impact and Kruzer/Anfibio as the Impact coil cables are a little shorter. But I love not having to fiddle around with velcro wraps. Just slide the cable up the shaft, screw it on and you're away. 
      More modes than you can poke a stick at! The Impact has the full suite of search modes. Actually is doesn't have 5-Tone mode as found on the Anfibio (Multi & 14 models), but it has both Gen and Gen Delta modes as well as another Impact exclusive......VLX modes. These are lower gain modes, for a quieter detecting experience. I have found they also perform well in mineralised soils. Even some of the suburban areas have heavy clay soils, and VLX1 works great. VLX2 is a low gain 4-tone mode, but is slightly deeper than VLX1 but still offers improved stability, and target ID's are very stable as well. VLX2 mode is probably the best all-round mode on the Impact, particularly if you have mineralised soils. 
      Wide armrest. Just another one of those personal things which I don't envy manufactures on, trying to make a detector to suit everyone out there! The Impact armrest feels great for me. It is also nice and thick, so doesn't flex like many other plastic armrests found on other detectors. 
      Trigger switch! When you get used to a detector with a ground balance/pin-point trigger, it is so hard going to a panel controlled one. It's not the end of the world, but the trigger is so natural. You ground balance more often just because it is so easy. 
      Anyway, I better stop there, as this is getting quite long. If you've got this far, hopefully you've learnt something you didn't know, and at very least, got you thinking about what you like or don't like on your current detector.

      There is a previous thread with a lot of speculation about just what is going on with a couple of the Nokta Impact all metal modes, the Gen(D) and Sta(D) modes. The thought was that they are mixed modes - in other words modes that are running both all metal and disc in parallel.
      The speculation garnered attention and we have now been provided this explanation directly from Nokta Software Team Leader Alper Tozan regarding these 2 modes: 

      ''I read a lot of comments about Gen (D) and STA (D) modes in some forums and firstly, I want to thank you about all your positive thoughts. On the other hand, I want to clarify one thing. In some forum discussions, these modes are defined as ‘’mix modes’’. These modes are not mix modes as mix modes typically result from at least two different software algorithms or hardware circuits working at the same time for decision making to discriminate and detect metals. These mix modes also show characteristics of two or more different modes at the same time including handicaps of each signal processing. 

      Gen (D) mode, on the other hand, is a true threshold based all metal mode with motion that can discriminate metal without needing any other hardware or higher order software process level. So it always behaves like a classical true threshold based all metal mode but with iron tone and tone break.''
      Frankly, for me that raises almost as many questions as it answers. Is an all metal mode that discriminates an all metal mode? Is it not instead a different kind of ferrous/non-ferrous discrimination mode? Whatever it is, it is unique, and that's enough for me! So I will do what I normally do and ignore what is going on under the hood and pay attention to just what it is these modes actually achieve by way of useful results in the field. More on that at a later date.
      From Nokta Impact Owners Manual, pages 12-13:
      Static Mode (STA)
      This is a non-motion mode. In other words, the device will generate an audio response when you hold the coil stationary without swinging over the target. The audio response increases in volume as the coil approaches the target. This mode is recommended for larger and deeper metals.
      In the STA mode, the device will generate the same audio tone for all metals and it will display the target ID on screen. At the same time, the ID scale will fill up to the right in proportion to the signal strength.
      Target ID range is 00-99. 00-40 are ferrous and 41-99 are non-ferrous metals. You can discriminate out all IDs below a certain ID by using the Disc. setting and simply avoid these metals in the field.
      When the device detects a discriminated metal, it will not produce an audio response or an ID. However, the ID scale will fill up to the right in proportion to the signal strength.
      The threshold in this mode is internal and cannot be adjusted by the user. Changes in the ground and temperature may lead to drifts in the threshold. Threshold drifts will be reflected in the ID scale either in the positive way (right side) or the negative way (left side). The device may emit an audible response in the positive drifts but not in the negative ones. When the threshold drifts, pull the trigger once to retune the detector. Retuning periodically while searching in this mode is recommended.
      IMPORTANT! For a more stable operation, try keeping the coil consistently at the same height above the ground where you retuned the detector.
      IMPORTANT! If you retune the detector over a target, the threshold will drift to the negative side and the device will no longer detect the target until the detector is retuned. In addition, the depth of the detector will also decrease.
      If the drifts are substantial and retuning does not improve the situation, increase the iSAT setting in the Expert Settings to a level where the drifts are eliminated (for detailed information on iSAT please refer to page 24). As the iSAT is increased, the device may detect weaker signals but will not be able to detect the targets anymore if you hold the coil stationary or sweep back and forth over the target. If the drifts still continue frequently, drop the gain to 39, decrease the iSAT and re-ground balance.
      Static Delta Mode (STA (D))
      In principle, it works the same as the static mode. The difference is that the static delta mode will generate the same tone for ferrous and non-ferrous targets at fringe depths but it will discriminate the shallow ferrous targets by emitting a low iron tone. Also, Disc. setting is not available in this mode.
      Please refer to Table 2 at the end of the manual for different settings used in STA and STA (D) modes.
      General Search (GEN)
      Different than the other modes, this mode features a threshold tone which is continuously heard in the background.
      General Search (GEN) mode is used in 2 different ways in the IMPACT: 1) with the Disc. setting disabled at 0 2) with Disc. enabled (non-zero). When the device is first turned on, Disc. setting will be off. When the Disc. is set at 0, the device does not discriminate targets and detects all targets (metals, mineralized rocks etc.). ID of the detected target is shown on the display (except for negative hot rocks) and the same audio tone is provided for all targets. The audio tone increases in pitch as the coil approaches the target. This is the typical All Metal mode found in most detectors.
      When using the Disc. Setting in this mode, the device will emit a low ferrous tone for all targets below the Disc. Setting, and a higher tone for all targets above the Disc. setting which changes in pitch as the coil approaches the target. Let's say you set the Disc. to 20. The device will generate a low iron tone for all metals with 0-20 ID and a higher tone for all targets with 21-99 ID. Upon target detection, the threshold will momentarily go silent and only the target audio response will be heard. The duration of the threshold's silence is directly related to the level of the iSAT.
      Gain, threshold and iSAT settings in this mode are optimized to provide the best performance on different terrains. You can modify these settings based on ground conditions.
      We recommend using the GEN mode when discrimination is not important and not using it in heavy trash areas or areas containing many hot rocks.
      Audio Boost in the General Search Mode
      This feature is not included in the settings on screen. Boosts the sound of weak signals received from small or deep targets making it easier for you to detect those uncertain targets. It is recommended that audio boost should be used on a temporary or as-needed basis because it will not only boost the target signal audio but it will also boost the volume of ground noise and false signals along with the threshold hum.
      Audio Boost consists of 5 levels (b1-b5). At start up, the Audio Boost level is set to low (b1). To increase the Audio Boost level, pull the trigger and press the minus (-) button simultaneously. Audio Boost will only work in the GEN mode.
      General Search Delta (GEN (D))
      In principle, it works the same as GEN mode. The difference is that the Gen (D) mode will generate the same tone for ferrous and non-ferrous targets at fringe depths but it will discriminate the shallow ferrous targets by emitting a low iron tone.
