Your objective

By the end, you'll be able to evaluate a hound's bark and GPS data to decide whether the dog is genuinely treed on a raccoon or is working a false tree or off-game situation.

Judgment ~8 min

Your dog has been chopping steadily for three minutes, GPS dot rock-solid, 200 yards out in a creek bottom. Perfect. Then you get closer and the chopping becomes erratic — faster, slower, a pause, then frantic again. Something is wrong. Is it the coon? A squirrel? A den the dog can smell but not reach? Every hunter has walked into that confusion in the dark. This lesson shows you how to read it before you arrive.

Quick recall

Quick recall — what two ear cues tell you the coon is treed versus still on the trail?

Rapid chop, not moving = treed; sustained bawl, moving = trailing Sustained bawl, not moving = treed; rapid chop, moving = trailing Both sound the same — only GPS tells you which it is

Show answer

Correct: Rapid chop, not moving = treed; sustained bawl, moving = trailing — Right. Stationary rapid chop = tree bark. Moving sustained bawl = trail bark. Both the quality and the movement of the bark matter.
Not quite: Sustained bawl, not moving = treed; rapid chop, moving = trailing — That's reversed. The tree bark is the rapid CHOP — the bawl is the trailing voice. A stationary bawl may mean a cold track, not a tree.
Not quite: Both sound the same — only GPS tells you which it is — The barks are distinctly different. The bawl is long and drawn-out; the chop is short and rapid. GPS confirms location and motion, but ears tell you bark quality.

Two tools: ears and GPS collar

Modern coon hunting relies on a two-channel system. Neither channel is complete alone.

Ears tell you:

Bark quality — chop or bawl?
Bark rhythm — steady or erratic?
Pitch changes — excited, distressed, or uncertain?

GPS collar tells you:

Dog’s position in the dark.
Whether the position is stationary or drifting.
Which dogs are together and which have split.

A dog that sounds treed but whose GPS dot is slowly moving is not truly treed — the coon bailed, or the dog drifted off-game after the tree.

Deep dive GPS collar systems used in SC coon hunting

Most SC coon hunters now run Garmin Alpha or similar systems. The handheld receiver shows each dog’s position updated every few seconds. A dog icon that is stationary with a “tree” alert (on systems with a treeing-detection feature) confirms the dog is locked up. Range varies by terrain — in thick creek bottoms with heavy canopy, real-world range is often shorter than the manufacturer’s spec. Always carry a backup plan (listen, mark your start point, and know the drainage direction) in case the collar signal drops.

What a genuine tree bark sounds like

A confirmed tree has all of the following:

Rapid chop — short, staccato barks at a fast, consistent pace.
Stationary source — the bark is coming from one spot, not tracking across the terrain.
GPS dot not moving — the collar confirms the dog is not drifting.
Steady, persistent — the dog does not stop and restart. It barks continuously until you arrive or the coon leaves.

What a false tree (off-game tree) looks like

A dog can give a tree bark on animals other than raccoon — squirrels, opossums, house cats, and sometimes nothing (slick tree). The bark may sound genuine but will often have tells:

Erratic rhythm — bursts of chopping followed by pauses and re-opening. A squirrel moves in the tree; the dog loses visual and then re-acquires it.
Slow drift on GPS — the dog is chopping but slowly following something around the base. The coon may have bailed, or the dog is on a squirrel that jumped to the next tree.
Short chopping sessions — the dog chops hard, goes quiet for 20 seconds, then chops again. A confident tree on a coon is rarely interrupted like this.
Off-game history — if this dog has a known tendency to tree squirrels (“junk game”), weight that history.

The why What 'off-game' means in coon hunting

Off-game (also called junk game or trash) includes any non-target animal a dog might strike and tree instead of a raccoon: squirrels, opossums, cats, rabbits, and occasionally deer or other large game. In UKC nite hunts, treeing off-game results in point penalties. In recreational hunting it means a long walk for nothing. Experienced hunters can sometimes read the bark quality alone to suspect off-game; beginners rely more heavily on GPS and what they see at the tree.

Using GPS and ears together — a decision diagram

Make the call

Decision

Your dog is chopping. You open the GPS and the dot is mostly stationary but moved about 30 yards in the last two minutes. The bark rhythm is choppy with a few pauses. What do you do?

Head straight in — the dog is chopping, that means treed

You push toward the dog and it is circling the base of an oak. There is nothing in the tree. The coon bailed when the bark went erratic. You burned effort and disturbed the area.

Watch the collar for two more minutes before moving

Good call. Over the next two minutes the dot stabilizes completely and the chop goes steady. The coon is up. You move in with confidence.

Call the dog back immediately — it's off-game

You may be right, but you gave up too soon. A drifting collar can mean the dog is circling the base checking for the coon's exact tree — it may still be a legitimate tree. Watch longer before calling off.

Test your read

Knowledge check

Your dog's GPS dot has not moved in four minutes. It is chopping rapidly and continuously. Which best describes this situation?

This looks like a genuine tree — stationary plus steady chop This is almost certainly a squirrel The tree is probably empty — the dog is bored

Show answer

Correct: This looks like a genuine tree — stationary plus steady chop — Right. Stationary GPS plus continuous rapid chop is the signature of a genuinely treed dog. Time to move in — but still shine the tree to confirm the animal before any shot.
Not quite: This is almost certainly a squirrel — A squirrel tree often shows erratic bark with pauses and a slowly drifting GPS. A completely stationary dot plus continuous chop is the strong signature of a legitimate tree — likely a coon.
Not quite: The tree is probably empty — the dog is bored — A stationary, continuously chopping dog is locked on something. A slick-tree dog often shows erratic chopping or drifts away. This signature looks legitimate.

Knowledge check

Your dog has been chopping for 90 seconds, then goes silent for 30 seconds, then starts chopping again from a point 50 yards from where it started. What is the most likely explanation?

The coon bailed to another tree or came down The dog was on a squirrel and gave up The dog is definitively treed — 50 yards is within normal GPS error

Show answer

Correct: The coon bailed to another tree or came down — Most likely. The coon exited the first tree and the dog followed — now chopping at a new location. Move toward the new position. The coon may have gone up again, or the dog may have temporarily lost it.
Not quite: The dog was on a squirrel and gave up — Possible, but a 50-yard drift with a re-open suggests the target moved. A bailed coon (one that came out of the tree and ran) is the more likely explanation for this specific pattern.
Not quite: The dog is definitively treed — 50 yards is within normal GPS error — 50-yard drift plus a silence gap is meaningful. GPS error in open terrain is typically 10–30 feet. A 50-yard movement with a pause suggests the coon moved, not collar error.

Take it to the woods

GPS-plus-ears tree-read drill

0/5

When the dog starts chopping: open the GPS and watch the dot position for at least 90 seconds before moving.
Rate the bark: steady chop or erratic with pauses? Log it mentally.
Check drift: did the dot move more than 30 yards while barking? If yes, treat as suspect.
Commit to walking in only when both channels agree — stationary GPS plus steady continuous chop.
Safety When you arrive: shine the tree before the gun comes up — always confirm the animal.

If you remember nothing else

A genuine tree bark is a rapid, steady chop from a stationary position — GPS dot not moving, bark not moving.
A false tree can sound like a tree bark but shows the dog slowly drifting — the coon bailed or the dog is off-game.
GPS plus ears together give you the full picture: collar tells you position and motion, ears tell you bark quality.
A dog 'stuck on a squirrel' or on a house cat will bark with the same intensity — you must get to the tree to confirm.
If you arrive and the tree is slick, trust the process: call the dog off, note the direction, and re-cast.

How ready do you feel?

How ready are you to use a GPS collar and your ears together to decide, before you reach the tree, whether your dog is on a raccoon or on something else?

Before you go — a quick look back

Distributed practice: one fast recall from an earlier lesson keeps it from fading.

Quick recall

From Strike, Trail, and Tree — what is the changeover, and what bark pattern signals it?

Show me the answer

Show answer

Correct: Show me the answer — The changeover is the shift from trailing bawl mouth to tree chop — the long, drawn-out bawl becomes a rapid, short, staccato chop. That shift is your cue to start moving to the dog.
