Use any loader you like, your marker will use the beam sensor (eye) to wait for a ball before firing. If you would like to fire at a faster rate, use a faster loader.

Tap the power button to turn on. Long press the power button to turn off. Long press the scroll button to toggle the eyes on and off.

Understanding your OLED and eyes

When you first turn your marker on, the eyes are enabled. They can be disabled for dry firing by holding the scroll button until the eye icon changes. They can be reenabled the same way.

Use a 1/8” allen key to adjust velocity through the hole in the front of your grip. The arrow on the diagram is anti clockwise, which is increasing velocity. Always use a chronograph, and use small adjustments.

DO NOT ADJUST YOUR VELOCITY ABOVE 300FPS, AND ALWAYS OBEY LOCAL LAWS AND REQUIREMENTS.

Your trigger has five adjustment screws, they are located in the front face of the trigger and also on the upper face. You can easily adjust these screws to personalise the feel of your trigger. When adjusting the trigger, use small adjustments.

The adjustments in detail are:

Magnet - this is an attracting magnet. Screw the screw upwards to make the magnet snap forwards harder.

Rake - this adjusts the at-rest position of the trigger. Screw upwards to angle the trigger backward.

Spring - this is a spring behind the trigger, screw this in to make the trigger return more forcefully.

Switch - screw this in to actuate the trigger earlier.

When adjusting the trigger, you may find it useful to remove the wrap, so you can see the microswitch.

CAUTION! WHEN ADJUSTING THE SWITCH SCREW, MAKE CERTAIN THAT YOU DO NOT ADJUST THE SCREW IN TOO FAR, AS THIS MAY RESULT IN DAMAGE TO YOUR MICROSWITCH. ENSURE THAT YOUR TRIGGER IS STOPPING ON THE TRIGGER STOP SCREW OR DAMAGE MAY RESULT.

Flip open the USB charge port, and connect the included power bank, or the included cable to any standard wall charger or computer to charge the battery.

Your GTX battery should charge fully within 1 hour if it is flat, or less if you are just topping it up. 

The battery is a LiPO, without memory effect, so you can charge it whenever you like, you do not need to wait for it to run flat.

If you lose your MacDev cable, a standard USB C cable is compatible.

The marker board is equipped with a tourney lock system. When the tourney lock system is activated, the marker cannot be reprogrammed on the field - making it tournament legal. If your board is in locked mode, you can view your settings, but a lock indicator will be shown on the right hand side of the screen, indicating that your board will need to be unlocked before settings may be changed.

The lock status can be changed by opening the Right hand side of the marker wrap around grip to gain access to the circuit board. The tournament lock is a black button. Press and hold the tourney lock button until an on screen indication of tourney lock status is shown.

Entering Program mode

To program the board, hold down the trigger whilst turning the marker on. When done correctly, you will see a message on your display screen indicating that programming mode is loading. You must continue to hold the trigger until the program mode is loaded, then release the trigger.

Finding and changing settings

Once in program mode, the OLED display will show a current setting. You can advance to the next setting by tapping the scroll button. You can go back to the previous setting by tapping the power button.

Once you have found a setting you would like to change, press and hold the trigger until the setting changes to red. The setting can now be changed by tapping the scroll button to increase its value (or change to a different option), or tapping the power button to decrease its value.

Once you have adjusted the setting to a value you would like, press and hold the trigger again until the setting returns to white, it has now been saved.

If your tourney lock is on, settings that can change the tournament legality of your marker will be locked. Their setting can be viewed, but not changed. You will know if the tournament lock is blocking editing, because a red lock symbol will show in the upper right hand corner of the screen, and the setting will not change to red as usual. If you would like to change a locked setting, you must open the wrap around grip and hold in the tourney lock button. This may be done inside program or normal running mode.

To exit program mode, turn the gun off, and when you turn it back on again, your new settings will be used.

Mode - The type of firing system used, semi auto, Millenium and PSP are common tournament modes. Ramp mode allows the programming of custom ramping behaviour.

ROF - This is the maximum rate of fire allowed by the marker. This setting is only observed if the next setting, rate of f ire cap is set on.

ROF cap - If the cap is enabled, the marker will be limited to the ROF setting. Otherwise, it will fire as fast as the laws of physics (and paint supply) will allow.

Dwell - the amount of time your solenoid is given power - the Prime should be set to a maximum of 12ms. If the weather is very cold, or your marker requires it, you may set this a little higher.

Debounce - the amount of bounce filtering applied by the software. This setting may be increased to remove unwanted trigger bounce.

Ball delay - this is a parameter used to give a paintball time to settle in the breach of the gun. If you have unexplained ball breakage, then you may need to increase this setting.

Eye sensitivity - the sensitivity of the software to changes in your eyes. Please do not change this parameter unless directed (default 10).

Forced shot - when enabled, this will allow the user to force a shot by holding the trigger in - even if the eyes cannot detect a ball. Set this to off, if you would not like to use this function.

FSDO time - FSDO stands for First Shot Drop Off. If you leave your gun for some time, and the first shot is lower than it should be, then you can use this parameter to correct it. This parameter is the time that the software waits before correcting for FSDO.

FSDO dwell - this is the amount of extra dwell given to the solenoid to overcome FSDO - if directed to do so by the above parameter.

Ramp semishots - this setting (and the other three below) is only used if you are using the Ramp firemode. This is the number of semi auto shots which must be fired before ramping is allowed.

Ramp rate - this is the number of shots per trigger pull when in ramp mode. Ramp ROF - this is the rate of fire which must be achieved and maintained to stay in ramp mode.

Ramp timeout - the amount of time the user can spend below the ramp ROF before ramping is exited. Auto power off - save power by automatically turning the marker off after 30 minutes.

Sound - sound can be enabled or disabled.

Auto power off - Your marker will automatically turn off after 30 minutes of inactivity if this is enabled.

Load/Save profiles - Your marker has two profile save slots. Once you have your marker set up as you like it, go to save profile and select one of the profiles. Hold the trigger in on the profile number you would like, and the current settings will be save to that profile slot. You can reload them at any time using the load profile option.

There is an option under load profile, to load factory defaults.

Software version - this is given in the format X.XX, a shot counter is given underneath.

Tech data - This page is for technicians to troubleshoot any problems with your marker, they may check this page during troubleshooting, or ask you for these numbers if you are requesting help online.
