Track Timing & Stopwatches

The Ultrak 460 Rainbow Set is the go-to timing solution for programs that need more than one stopwatch working at once. Six individually colored watches let coaches assign a specific color to each lane, drill station, athlete group, or event — eliminating mix-ups during fast-paced sessions and making data recall faster and more organized after every timed set.

• • Six Rainbow Colors in One Set – Includes one each of red, blue, yellow, green, orange, and purple Ultrak 460 stopwatches, making it simple to color-assign timing responsibilities across lanes, stations, or coaching staff without watches getting confused or mixed up during multi-group sessions
  • 16 Lap or Cumulative Split Memory – Each watch stores up to 16 recallable lap or cumulative split times, allowing coaches to capture a full set of athlete performances and recall any individual split both during and after the timed event without losing data
  • 1/1000 Second Resolution up to 100 Hours – Measures timing events to one-thousandth of a second across a full range up to 100 hours, making each watch equally capable of timing short sprints, long-distance events, and extended fitness assessments with the same precise accuracy
  • Lap Counter to 99 – Built-in lap counter tracks up to 99 laps independently of the split memory function, supporting distance running, swimming, cycling, and any repetition-based drill that requires separate lap count tracking alongside elapsed time
  • Extra-Large Display with Water Resistance – Oversized LCD display keeps time readings clearly visible from a distance during outdoor and gymnasium use, while the water-resistant casing protects each watch through sweat, rain, and typical athletic environment exposure
  • Lithium Battery with 5-Year Warranty – Each watch runs on a long-life CR2032 lithium battery and is backed by a 5-year manufacturer warranty, with a lanyard included in every unit for secure, hands-free carry during active coaching sessions

The Ultrak 460 is the go-to stopwatch for coaches who need more than a basic timer. It stores and recalls 16 splits mid-session, displays both lap and running time simultaneously, and runs up to 100 hours — all in a water-resistant, lanyard-ready package.

• • 16 Recallable Lap or Cumulative Splits — Stores up to 16 lap or cumulative split times that can be recalled both during and after the timed event, with each reading held on the display for 10 seconds before the automatic split release returns to running event time
  • Dual 2-Line Display — Two-line LCD shows both the current split and the running event time simultaneously, so coaches can read lap data without losing track of overall elapsed time during active timing sessions
  • 1/1000-Second Resolution to 100 Hours — Times events to one-thousandth of a second across a full 100-hour range, covering sprint intervals, distance runs, swim sets, and extended fitness assessments from a single watch
  • Lap Counter to 99 — Independent lap counter tracks up to 99 laps separately from the split memory, supporting distance running, swimming, and repetition-based drills alongside elapsed time tracking
  • Water-Resistant with Extra-Large Display — Water-resistant casing handles sweat and outdoor conditions, while the oversized LCD remains clearly readable from a distance during fast-paced practice sessions
  • Lithium Battery, Lanyard Included, 5-Year Warranty — Long-life CR2032 lithium battery, included lanyard for hands-free carry, and a 5-year manufacturer warranty; available in black or as part of the 6-watch rainbow color set

Built for coaches who run interval and shuttle work, the Ultrak 480 pairs eight recallable splits with a presettable pacer and a dedicated 30-second shuttle countdown.

The Ultrak 598 combines a 2000-event memory professional stopwatch and a built-in thermal printer in a single compact unit — no separate printer, no extra cables at the timing station. For officials who want recorded, printed results without assembling a multi-piece setup, it's the streamlined all-in-one answer: time the event and print the results from the same device.

Key features & specs

• 2000-event memory for high-capacity recording
• Built-in thermal printer — all-in-one design, no separate printer needed
• Prints instant results directly from the device
• Multiple-event memory with event segregation
• Lap and cumulative split modes

Usage tip: Reach for the 598 when you want the simplest possible printing station — one unit to carry, set up, and operate — and keep spare thermal rolls in your kit. Store it indoors away from heat and humidity, keep thermal paper cool and dry, and wipe the housing clean with a dry cloth between meets.

The Ultrak 599-SET bundles everything a timing crew needs for professional printed results in one package: the legendary Ultrak 499 stopwatch paired with the updated 599-P thermal printer. It's the best-value route to a complete timing-and-printing station for meet directors and officials who want recorded, hard-copy results without sourcing the pieces separately.

Key features & specs

• Includes the Ultrak 499 stopwatch and the 599-P thermal printer
• 2000-lap memory stopwatch with multiple-event segregation
• Thermal printer for instant, ink-free printed results
• Direct stopwatch-to-printer connection for station-side output
• Best value for a complete 499-plus-printer setup
• Everything a timing crew needs in one purchase

Usage tip: Set up the 499 and 599-P together at the finish line so laps and splits print as they're recorded, and keep spare 499-PAPER thermal rolls on hand so you never run dry mid-event. Buying the two as a bundle guarantees the stopwatch and printer are matched and ready to connect out of the box, which saves setup time on meet day. Store both units indoors away from heat and humidity, keep thermal paper cool and dry to preserve print quality, and wipe the housings clean with a dry cloth between meets.

The Ultrak 599-P is the updated thermal printer built to pair directly with the Ultrak 499 stopwatch, turning stored timing data into instant printed records at the timing station. Its refreshed internals deliver faster, more reliable printing during competition — essential wherever officials need hard-copy lap and split results in hand rather than transcribing from a screen.

Key features & specs

• Updated printer model designed for the Ultrak 499 stopwatch
• Thermal printing — no ink or ribbon required
• Instant printed results of lap and split times
• Uses standard 499-PAPER thermal rolls
• Connects directly to the 499 for station-side printing

Usage tip: Keep spare 499-PAPER rolls in your meet kit so you never run out mid-event, and print results as you go to speed up scoring. Store the printer indoors away from heat and humidity — thermal paper and rolls should be kept cool and dry to preserve print quality — and wipe the housing clean with a dry cloth.

The Ultrak L10-B is the individual lane button that lets your multi-lane timing system grow with your program — add capacity one lane at a time or replace a worn button without buying a whole new set. It works with both the Ultrak L10 and L20 systems, so it's the right spare and expansion part to keep on hand as meet sizes change season to season.

Key features & specs

• Compatible with both Ultrak L10 and L20 multi-lane timing systems
• Individual lane trigger button for a single finish line position
• Wired connection to the base timing unit
• Use to expand lane count incrementally or replace a damaged button

Usage tip: Keep a spare or two in your timing kit so a failed button never stalls a meet, and add buttons as your lane count grows. Keep the button and its cable dry, coil the cable loosely to prevent wire fatigue, and store indoors in your timing case.

The Ultrak L20-10B delivers full ten-lane simultaneous timing — the complete solution for championship track meets that run wide fields and demand a recorded finish in every lane. With Windows software for results management and compatibility with both thermal printers and FinishLynx photo-finish systems, it scales from heats to finals and integrates into a serious meet-management workflow.

Key features & specs

• Ten-lane button set for full championship-level coverage
• Windows interface software included for results management
• Simultaneous finish capture across all ten lanes
• Compatible with thermal printer for instant printed results
• Integrates with FinishLynx photo-finish systems
• Built for wide-field invitationals and championship-level events

Usage tip: Use the full ten-lane setup for invitationals and championship finals, and pair it with FinishLynx when you need photo-finish verification on close races. Because it covers every lane of a ten-lane track simultaneously, it scales cleanly from preliminary heats through finals without reconfiguration, and a thermal printer adds instant hard-copy results at the scorer's table. Keep the buttons and cables dry, coil the cables loosely for storage to protect the wiring, and keep the components indoors in a protective case between meets.

The Ultrak L20-8B is configured for standard eight-lane tracks, delivering individual finish-time capture for every lane at once — exactly what most high school and collegiate facilities need. With a dedicated button per lane and Windows-based results software, it gives meet directors and timing officials a dependable, straightforward way to record and manage a full heat's finishes.

Key features & specs

• Eight-lane button set — covers standard track configurations
• Windows interface software included for results management
• Simultaneous eight-lane finish-time capture
• Thermal printer compatible for instant printed results
• Expandable with additional L10-B lane buttons
• The standard-track workhorse for high school and college meets

Usage tip: Match one timer to each lane button so every finish is recorded independently across the full eight-lane field, and add a thermal printer for on-site results. This configuration mirrors the standard eight-lane oval, so it drops straight into most high school and collegiate facilities without adaptation. Keep the buttons and cables dry during meets, coil the cables loosely to avoid strain on the wiring, and store the components indoors in a dry case between events to protect the electronics.

The Ultrak L20-6B captures finish times for up to six lanes simultaneously, making it a practical timing solution for small-to-medium track meets where every lane needs its own recorded finish. Each lane gets a dedicated button, and the included Windows software pulls results together for meet directors and timing officials. When your program outgrows six lanes, the system expands rather than forcing a replacement.

Key features & specs

• Six-lane button set for simultaneous multi-lane capture
• Windows interface software included for results management
• Simultaneous finish capture across all lanes
• Expandable up to 10-plus lanes with additional L10-B buttons
• Compatible with thermal printer for instant printed results
• A dependable middle-tier setup for growing track programs

Usage tip: Assign one timer per lane button for clean, simultaneous finishes across the field, and add a thermal printer when you need hard-copy results at the meet. This six-lane configuration handles most junior high and small high school meets, and expands with L10-B buttons when your program moves up to full eight- or ten-lane competition. Keep buttons and cables dry during use, coil the cables loosely to prevent wire fatigue, and store the set indoors in a protective case between meets.

The Ultrak L20-XC is the entry point to the L20 multi-lane timing system — a smart first step for programs that want accurate, expandable finish timing without buying a full championship setup on day one. This basic set captures finish times for a single lane and grows with you: add lane buttons as your meets get bigger. Windows-compatible software makes recording and managing results straightforward.

Key features & specs

• One-lane button configuration for single-lane finish capture
• Windows-compatible software interface included
• Expandable with additional L10-B lane buttons as your program grows
• Compatible with thermal printer output for printed results
• Ideal for small events, practice timing, and developing programs

Usage tip: Start here for practice and small dual meets, then add L10-B buttons to scale up to multi-lane timing without replacing the system. Keep the buttons and cables dry, coil cables loosely for storage, and store the components indoors in a dry case.
