    Battery Details The device is supplied with 4 pieces of AA Alkaline batteries. To remove the battery compartment cover, press on the latch and pull out. Insert the batteries observing correct polarity of + (plus) and - (minus). The device can be used for approximately 20-25 hours when the batteries are fully charged.

    Quick Guide Assemble the device as per the instructions on page 1. Insert the batteries by paying attention to +/- polarity. Rotate the on/off switch located behind the device clockwise to turn on the device. This switch also adjusts the volume. When the device is turned on, it will start in the Three Tone mode.

  • Page 10: Menu

    5 search modes adapted to different ground conditions and target types are offered by RACER 2. Names of the search modes are defined as ALL METAL, TWO TONE, THREE TONE, BEACH and DEEP on the menu screen. You can easily switch between the modes by using the direction keys during your search.
  • Page 11 Menu ID FILTER is the ability of the device to ignore all metals below a certain TARGET ID. In the ID FILTER process, the filtered ID range is shown with lines on the ID scale and every 2 consecutive IDs are represented with 1 line. For example, if you set the ID FILTER to 30, 15 lines will be shown between the 0-30 ID range on the scale and the device will not produce a warning tone for any metals with IDs between 0-30.
  • Page 12 Menu NOTCH FILTER adjustment applies to the selected search mode only. The change does not affect the other modes. Since there is no discrimination in the ALL METAL mode, this setting is inactive in this mode. IRON AUDIO It adjusts or turns off the volume of the low iron tone. IRON AUDIO range is 00-10.
  • Page 13 Menu ALL METAL ONLY THRESHOLD This setting is used to adjust the humming sound, referred to as the threshold sound, which is continuously heard in the background in the All Metal mode. It is used to increase the target signal, in other words, the depth of the device. For more details, please read Gain, Threshold and iSAT section.
  • Page 14 Factory Default /Save (FD/Save) With the FD/Save feature of the RACER 2, you can save your settings or restore factory defaults. Save function saves all settings except for the ground balance and tracking. The device starts in the last mode where the save function was performed. For example, you changed the settings of both the All Metal mode and the Deep Mode and you saved the settings while in the Deep mode.
  • Page 15 Menu To restore factory defaults, select FD/Save on screen and press the minus (-) button. FD will be displayed. To confirm, pull the trigger once and release. FD will stay on screen for a short period of time and it will disappear when the process is completed. Other Settings Not Shown on Screen FREQ.

  • Page 16: Modes

    MODES All Metal It is the deepest mode of the device. Different than the other modes, this mode features a threshold tone which is continuously heard in the background. The device does not discriminate targets while in the All Metal mode and detects all targets (metal, mineralized rocks etc.).
  • Page 17 It is recommended to modify this value according to the type of target. Beach Mode It is the special mode of RACER 2 developed for conductive grounds (wet sand beach, grounds with alkali soil etc.). The feature of this mode is its ability to ignore iron and similar targets in this group and to perform ground balance on any type of ground.

  • Page 18: Ground Balance

    Ground Balance Ground balance can be performed in three ways in RACER 2: Automatic, Manual and TRACKING. If the trigger is pushed forward while performing automatic or manual ground balance, the device will switch to the All Metal mode automatically on the background without any indication to the user, regardless of the selected search mode.
  • Page 19 RACER 2 is designed to allow for automatic ground balancing conveniently on any type of ground. Therefore, it is recommended to perform automatic ground balance upon start up.
  • Page 20 Ground Balance The device will return to the main screen automatically after a moment upon completion of ground balance. To return immediately, just pull and release the trigger once. IMPORTANT! Experienced detectorists adjust the ground balance setting to little positive response (weak but audible sound is produced when moving the search coil closer to ground).

  • Page 21: Gain, Isat And Threshold

    Ground Balance Important Details Concerning Ground Balance 1) Upon start up, the ground balance value is set as 90. The device can perform ground balance automatically within the range of 40-90 in all modes and 0-90 in the Beach mode. 2) If the ground mineralization is too low, automatic ground balance may fail to work in other modes except for the Beach mode.
  • Page 22 Gain, iSAT and Threshold It is recommended for average users to leave this setting at its default value and for experienced users to adjust to the highest level where they can still hear the weak target signals. You cannot search in the All Metal mode without ground balancing. Changes that occur in the ground effect after ground balancing cause false signals or disruption in the threshold hum.

  • Page 23: Target Id And Id Filter

    Target ID and ID Filtering As explained before, target ID is a 2 digit number defining the target, produced by the metal detector while the search coil goes over a target The number is shown on the display as TARGET ID. In some cases, the device may produce multiple IDs for the same target.
  • Page 24 Target ID and ID Filtering It may take some time and experience to utilize the Target ID feature in your search area because Target IDs as well as the depths the IDs are generated by different brands and models of detectors are also different. As indicated before, ID FILTER feature is the ability of the device to perform search without producing warning tones for unwanted metals.

  • Page 25: Pinpoint

    Pinpoint is to find the center or the exact location of a detected target. RACER 2 is a motion detector, in other words, you are required to move the search coil over the target or the target over the search coil in order for the device to detect the target. The pinpoint mode is a non-motion mode.

  • Page 26: Target Distance

    ''IS'' will be displayed. Swinging Speed and Target Identification RACER 2 is a detector with very high detecting speed. When you detect a target with RACER 2, you should make wider passes instead of narrowing the sweeps and making quick sweeps over the target like in other metal detectors, in order to receive an accurate ID from the target.

  • Page 27: Magnetic Mineralization Indicator

    Magnetic Mineralization Indicator The Magnetic Mineralization Indicator consists of 5 levels. The indicator is shown empty at low mineral levels during search and at start up. In areas where the magnetic mineral level is high, the indicator level increases according to the intensity. This measurement can be summarized as the level of magnetic property and intensity of the ground.

  • Page 28: Tracking And Effects Of Rocks

    Metals Under Rocks RACER 2 increases the possibility of detecting metal targets under mineralized rocks through the proper adjustment of your settings. The combined effect created by the rock and metal together is lower than the effect that the metal creates by itself and the displayed ID will be different than the metal's expected ID.

  • Page 29: Searching In Shallow Water And Beach

    As explained before, salt water and alkali grounds are significantly conductive and cause effects similar to iron in detectors. RACER 2’s Beach mode is specially designed for such conditions. You can perform your search easily using the Beach mode without requiring any special settings.

  • Page 30: Messages

    Messages Warning messages are shown on the bottom of the display during search. Messages that may appear are as follows: Saturation It appears on the display simultaneously with the overload alarm sounding like a siren. This happens when the search coil encounters a near surface or a very large object. The device reverts back to normal operation if you lift the coil up.
