In short: Training markers are not all the same tool. The right choice depends on what you're marking (agility grids, zone boundaries, full court lines, or drill-coded sequences), the surface (outdoor grass or turf, gym floor, sand), and how many you need for your squad and session structure. Get those three right and the rest follows.
We're Eco Walker, by TAY Sports — a manufacturer of flat disc markers, shaped training markers, and court boundary markers for clubs, schools, PE departments, and academies. Here's the buying framework we'd hand any coach building a kit from scratch.
The four marker types — which does what
1. Flat disc markers (the coach's foundation)
Flat disc cones — typically 23–28 cm diameter, 2–3 mm thick — lie completely flat on any surface. Because they have no height, players can run directly through or over them without risk of tripping, and they don't blow across the pitch in wind the way a tall cone does. That makes flat discs the most versatile marker in the kit: boundary lines, grid squares, drill start and end points, zone markers, and touch-line substitutes for small-sided games.
A flat TPE disc on grass or artificial turf stays exactly where you placed it. A dome cone blown into the next grid corrupts the drill. For any session that involves footwork, small-sided boundaries, or drills where players pass through the markers, flat discs are the correct choice.
Best for: Grid drills, zone and pitch boundaries, agility setups, general-purpose use on any surface.
2. Dome (tall) cones
The classic 15–23 cm tall cone is visible from distance and still earns its place as a landmark or slalom reference point. The trade-off: height means a trip hazard at pace, wind instability, and a bulkier stack to transport and store. For sessions where you need a visible reference point 40 metres away — a goalkeeper's starting cone, a relay turning point, an end-zone marker — the dome cone works. For close-contact footwork and agility setups, flat discs are safer and more stable.
Best for: Slalom lanes, high-visibility distance landmarks, relay turning points.
3. Shaped markers — the drill-coding layer
Shaped markers (stars, arrows, targets, numbered discs) don't replace flat cones — they add a coding layer on top of a flat disc layout. An arrow tells the player which direction to accelerate. A numbered marker defines a sequence. A star or target designates the finishing point of a drill pattern. You use shaped markers alongside flat discs, not instead of them: lay the flat discs as the grid, then drop shaped markers at the decision points.
Best for: Drill sequencing, direction cues, reaction training, SAQ sessions with complex patterns.
4. Court boundary markers
Court boundary markers are a distinct product category: longer strips or linked sections laid end-to-end to outline full court lines — pickleball, badminton, volleyball, basketball — on any surface without tape or chalk. They're not interchangeable with drill discs; they serve a completely different function.
Best for: Temporary court layouts on gym floors, grass, and multi-sport surfaces without tape, paint, or chalk.
Surface compatibility
| Surface | Flat disc | Dome cone | Shaped marker | Court boundary |
|---|---|---|---|---|
| Natural grass | ✓ grips | ✓ stable | ✓ | ✓ |
| Artificial turf | ✓ best | ✓ ok | ✓ | ✓ |
| Gym / hardwood | ✓ non-slip TPE | ✗ may scratch | ✓ | ✓ ideal |
| Sand / beach | ✓ | ✓ | ✓ | limited |
| Concrete / tarmac | ✓ | ✓ | ✓ | ✓ |
The critical variable for gym and hardwood use is the underside material. A flat marker with a textured non-slip TPE base stays put on a wooden floor without scratching it. A dome cone's hard base can scratch or leave residue. If your markers will be used indoors, confirm the underside is smooth, flexible TPE before buying.
How many markers do you actually need?
The most common buying mistake is underestimating quantity. A coach buys a 20-piece set, gets mid-drill and realises the next grid needs 12 more discs, and spends the rest of the session improvising.
| Context | Minimum | Recommended |
|---|---|---|
| Backyard / home practice (1–2 players) | 20 | 30–40 |
| Small group coaching (4–6 players) | 40 | 50–60 |
| Full squad practice (10–15 players) | 60 | 80–100 |
| Full club (multiple simultaneous sessions) | 100 | 150–200+ |
| PE department (multi-sport, multi-group) | 80 | 120–150 |
Colour variety matters almost as much as count. A 50-piece set in five colours is more useful than 50 identical orange discs — colour-coded zones, team differentiation, and drill-phase coding are how coaches run complex sessions efficiently.
Material and durability — what to look for
Most flat disc markers are made from TPE (thermoplastic elastomer) or PVC. Four things to check before buying:
- Thickness: 2–3 mm is the working standard. Thinner becomes brittle in cold; thicker is harder to transport in volume.
- UV stability: Markers used outdoors regularly fade and crack without UV stabilisation. Cheap unbranded discs often degrade within a season.
- Underside grip: A textured non-slip base for outdoor surfaces; smooth flexible TPE for indoor hardwood.
- Edge profile: A gently rounded or rolled edge is more durable than a sharp flat edge, which can crack under repeated footsteps or freeze-split in winter storage.
Use cases at a glance
Agility and SAQ training — The flat disc's primary domain. Lay out ladder-style footwork grids, T-drill courses, reaction boxes, and shuttle run stations without trip hazards. Add arrow or target shaped markers at decision points.
General training and drill sessions — For any coach building a kit from scratch, flat discs are the foundation; shaped markers and dome cones are the layers you add on top.
PE departments — One marker kit can serve every sport across a term: football grids, basketball zones, multi-sport playing areas, and temporary court lines. PE departments typically need higher total quantities (120–150 flat discs minimum) plus a court boundary set.
Small-sided game boundaries — Flat discs laid along touch lines and goal lines create clean small-sided game pitches during training without permanent marking. This is often the highest-volume use at club level.
Buying for a club or institution
For clubs, schools, and multi-team programmes, the per-unit cost of markers drops significantly at volume. A 100-piece pack is substantially cheaper per disc than ten 10-piece packs, and having enough markers for two simultaneous sessions removes the logistical problem of re-splitting a shared kit between coaches.

Putting it together
- Start with flat discs as your foundation — they work on every surface and every drill type.
- Buy more than you think — use the quantity table above and add a 20–30% buffer for simultaneous drills.
- Choose multi-colour — the marginal cost is low, the coaching flexibility is high.
- Add shaped markers when your drills need coded direction or sequence cues.
- Add dome cones only if you need high-visibility landmarks at distance.
- Add court boundary markers if you run multi-sport or PE sessions.
- Check the material for your surface — non-slip TPE for indoor, UV-stable for outdoor.
