+  #### `Enable_Velocity_Detection`
+
+  - **Description:**
+
+    Enables bite detection using the fishing bobber velocity packet.
+
+    This improves reliability when bobber X/Z movement is constrained (for example by blocks near the water surface).

+
+    Velocity Y threshold in blocks/tick for velocity-based bite detection.

+    Values below this threshold are considered a bite. Keep this value negative.
