Buck Finder
It puts legal light, sun, rut, wind, and calls in one plan.
Use your state rule for legal shooting light. See sunrise and sunset. Follow the rut phase for your county. See the movement windows, wind, scent path, and calling plan.
WHITETAIL FIELD PLANNING
Hockline puts rut data, legal light, wind, maps, and sit notes in one place.

THE FIELD PLAN
Each tool starts with a plain answer. Each evidence claim shows its label.
It puts legal light, sun, rut, wind, and calls in one plan.
Use your state rule for legal shooting light. See sunrise and sunset. Follow the rut phase for your county. See the movement windows, wind, scent path, and calling plan.
It explains the saying without pretending a hock can score a hunt.
Tarsal glands sit inside the rear leg at the hock. Deer scent glands help carry social and breeding information. A dark hock can also show urine, mud, or wet hair. MU Extension source Hockline labels the visual read as expert opinion, not a peer-reviewed rut meter.
expert opinionIt brings the field layers together before you leave the truck.
Plan with satellite, topo, public land, rivers, trails, wildfire, radar, wind flow, and offline maps. Map layers are a product feature, not a promise of a harvest.
It shows solunar majors and minors, then tells you what the evidence says.
Deer feed in cycles every 4-6 hours: at sunrise, around midday, at sunset and twice at night. Source Moon data is logged for comparison. GPS studies found moon phase does not predict movement, so Hockline never uses it to rate a day.
agencyIt turns each sit into a record you can inspect later.
Log wind, moon, rut phase, stand pressure, calls, deer, and what happened. My Patterns keeps your own notes separate from published evidence.
It compares two grunt sits, two bleat sits, and one silent sit.
The data uses a 2:2:1 allocation. The grunt script is six short grunts and one drawn-out grunt. The bleat script uses three can inversions. The silent arm makes the same motions without sound.
inferenceIt helps you read the plan and its limits before a sit.
Coach can explain rut, wind, light, maps, and logs. It is not a hunting authority. Check the agency guide and use your own judgment.
It helps the people at home know the plan and the check-in.
Use a hunt plan, safe check-in, and live share. A share page shows the last location received. Call 911 if you cannot reach someone.
It gives hunters a place to compare notes without hiding the source.
Contacts, tagging, posts, messages, and sharing to Facebook are planned community tools. Do not post another person's location without permission.
EVIDENCE HONESTY
Every claim is labelled peer-reviewed, agency, expert opinion, inference, or computed. Moon data is logged, never used to rate a day. Phase calendars are inference when the data supports a movement anchor.
What the evidence says
Deer movement peaks within about an hour of sunrise and sunset, in every season and rut phase. Source
Moon phase has a negligible effect on deer movement. Source
No peer-reviewed controlled trial of grunt calls, estrous bleats or decoys, and no head-to-head comparison of call types, was found. Source
RUT DATA
Hockline publishes the tables it has. It keeps agency methods, source links, and verification flags beside the dates.
STATE PICKER
30 states with published rut data in this build. The picker includes every state data folder. Some pages say the agency does not publish rut timing.
QUESTIONS HUNTERS ASK
Georgia's DNR map gives a county-level peak movement window. Ware County is Oct 20 to Oct 26; choose your county because the date changes across the state. Georgia DNR source
Tarsal glands sit inside the rear leg at the hock and help carry deer scent information. A dark hock can also show urine, mud, or wet hair. MU Extension explains the scent-gland biology. Hockline labels the visual read as expert opinion, not a movement score.
Moon phase has a negligible effect on deer movement. Read the cited agency summary. Hockline logs moon data but never uses it to rate a day.
Using electronically amplified sounds or recorded calls to hunt game is unlawful, except for listed species such as bobcats, crows and foxes. It is not legal for deer. Check the Georgia rule.
Deer movement peaks within about an hour of sunrise and sunset, in every season and rut phase. Midday movement rises in peak breeding, but the data says it does not match the early and late windows. Source
No peer-reviewed controlled trial of grunt calls, estrous bleats or decoys, and no head-to-head comparison of call types, was found. The tending grunt is documented, but the 2:2:1 Call Test is labelled expert opinion or inference. Source
