From the ND Game and Fish website:
Deer Bow Season – A bow must be pulled, held, and released by hand. Any release aid may be used providing it is hand operated, the shooter supports the draw weight of the bow, and the release is not attached to any part of the bow other than at the bowstring. A compound bow used for hunting deer must have at least 35 pounds of draw at 28 inches or less draw length. Recurve and long bows used for hunting deer must have at least 35 pounds of draw at 28 inches. Arrows must be at least 24 inches long, tipped with a metal broadhead, with at least two sharp cutting edges, and have a cutting diameter of at least 3/4 inch (i.e., not able to pass through a 3/4 inch ring). It is illegal to hunt big game with barbed arrows. Broadheads with mechanical or retractable blades not manufactured to stay open are legal. Telescopic sights, range finding devices, battery-powered or electronically lighted sights or other electronic devices attached to the bow, or the arrow, are not permitted . Handheld range finding devices are legal. Arrows capable of causing damage or injury in excess of that inflicted by the cutting edges of the broadhead are prohibited (e.g., explosive arrow points, arrows tipped with drugs or chemicals, and pneumatic or hydraulic shafts are illegal). No firearms, except handguns, may be in the hunter’s possession while hunting with a deer bow license. However, handguns may not be used in any manner to assist in the harvest of a deer with an archery license.
