These examples are tested and known to work well, so if your dart is similar in color to any of the following it will work reliably:

• all heavy worker darts
• all gen3 worker darts (orange tip, any foam color)
• all gen2 worker darts (black tip, white / yellow / green foam)
• ACC (cone black tip, orange foam)
• bamboo darts (orange tip, red / green foam)
• Adventure Force Pro red tip grey foam
• Dart Zone max grey tip red foam

Utilizes two active IR sensors, and does not require you to be in a brightly lit location. Optimized for indoor use, but will also work outside with some kind of sun shade. Will function even in the pitch dark - can be used indoors, or outside at night. 

Disclaimers: 3D Printing artifacts and blemishes may be visible in some cases- up to the user to sand / paint as desired. Darts with black or grey foam AND tip will NOT work with this product. At least one part of the dart must be a lighter color. It is normal for battery % to drop rapidly during first few minutes of usage. Battery % will recover when device is turned off for awhile. A single 9V will last up to 8 hours, assuming device is used in multiple sessions, and not left on for a single 4 hour sitting.
