Bluetooth TrackableNock


World’s 1st Bluetooth Enabled Trackable Nock

Breadcrumb was founded on one simple thought: no one should ever lose an arrow. Hunters waste countless hours each season searching for arrows that missed their mark, and a fully loaded arrow can easily set you back $60. Our water-resistant, Bluetooth-enabled nock saves you time and money and is activated upon firing. To locate your arrow, simply open the app on your phone. It will automatically scan for the activated nock and show the distance to your lost arrow once it connects. If you’re unable to see your arrow, you can activate its flashing light or sound capability from up to 100 yards away. Spend less time searching and more time hunting.

The brightest idea in archery

  1. Precise Contact Points

    Engineered and molded for a controlled and consistent arrow release to ensure accuracy

    Easy On/Off Activation

    No magnets, pullout switches or knife points required… The Breadcrumb Bluetooth Trackable Nock is armed and ready with a simple touch of its water-resistant activation button.

  2. Ultra Bright LED

    Activated upon firing, Breadcrumb’s LED light acts as an illuminated tracer in flight, and once the arrow lands it becomes a pulsating beacon to aid in retrieval.

  3. PCB Processor

    The brains behind it all, this tiny microprocessor controls the light, sound and Bluetooth tracking functions.


    This powerful piece of hardware uses a motion sensor to activate when fired and not while in your quiver.

    Sound Chip & Speaker

    When an arrow is covered by earth and brush, this unique nock feature calls out to provide you its hidden location

    Bluetooth Transmitter

    With a range up to 50+ yards, this tech component reaches out to communicate directly with your smart phone.

  4. Replaceable Battery

    Providing more than 35 hours of continuous tracking power, the replaceable battery is controlled by the PCB to monitor battery life and conserve energy when needed.
