Excellent and easy to use product

I've purchased this product for my track bike and what a product it is, very easy to wire onto the battery, very easy to use, instructions are very clear. Used it at snetterton and all you have to do go through the settings to start and the lap timer does the rest and everytime you go over the start / finish line the clock resets by itself and also tells you if you're faster or slower than other laps. I would highly recommend this product to anyone thinking of buying a lap timer

Great little package

Easy to fit, had it wired up in minutes, and does exactly what I need from it. I do a few track days, novice group only, and this is a great fun toy to look back over your lap times and see how you are improving. Probably not enough for the big boys but super for me.

Light, easy and correct timing

I had the previous version which does not have automatic recognition of the track. This does it automatically which means that you don't need to think about anything else then what is in front of you. Perfect product, easy install and cheap compared to competition.

Good GPS

Works very well, but if you want to see your position on track then you want the non-lite version. You can upgrade the software in the unit later, but it will cost more than buying the upgraded one out of the box.

DOUBLE CONSTELLATION GPS / GLONASS RECEIVER AND ANTENNA BUILT IN THE INSTRUMENT: The Stealth's shock-proof ABS body accommodates the new double constellation receiver which uses in symbiosis the American GPS and the Russian GLONASS satellite systems. This solution dramatically increases the precision due to the high number of satellites involved.

YOU CAN SAY GOOD-BYE TO ALL UNPRACTICAL INFRARED TRANSMITTERS ARRANGED ON THE PIT WALL: The use of the GPS and GLONASS system intended to detect the lap-time allows the Stealth GPS-4 to be completely autonomous, requiring no beacon transmitters, such as the infrared ones used by old generation systems.
Everything is getting much simpler; it is no longer necessary to arrange the transmitter and to recharge the battery, which is extremely annoying and unpractical with the risk of forgetting it on the wall or having it stolen.

MANAGEMENT OF THE FINISH LINE AND 3 INTERMEDIATES: You can set up the coordinates of 4 trigger lines (main finish line and 3 optional intermediates). Whenever you cross a finish line or an intermediate, the lap-timer will indicate the relative split time and store its value. You can therefore quickly evaluate your own performance even if you are riding along a part of the track far from the main straight stretch, which would be expensive and unpractical if you used any other type of lap timer.

INDICATION OF THE ACHIEVABLE IDEAL TIME: By managing intermediates, the lap-timer can calculate the time a rider can ideally achieve for every single session. This function is obtained by adding the best sector times. This will help you understand the lap time you might have achieved if there had been no traffic in a specific point of the track or if you had done a lap on top of your absolute performance.

DOUBLE FUNCTION BEST LAP LED: The 'BEST LAP' will turn on if you have improved your previous lap and it will blink if the lap you have just done is the best of the session. This solution will supply the rider with all the information necessary for performance without any distraction. If you have set up intermediate finish lines, the LED is also enabled whenever you cross an intermediate. This means that this instrument is extremely useful to monitor without any distraction whether you are improving compared to the same intermediate time of the previous lap or whether you have just accomplished the best intermediate time of the session.

GPS SPEED MEASUREMENT: The advantage of using a GPS and GLONASS system is that you can measure the vehicle speed with the highest degree of accuracy without having to install any sensor on the vehicle. No user setup is required; and all measurements are always accurate, not altered by the inclination of the vehicle or wheel spinning.

DOUBLE HOUR METER FOR THE PERFECT PERIODICAL MAINTENANCE OF THE VEHICLE: The Stealth GPS-4 Lite has also got two hour-meters that can be separately reset for the periodical maintenance of the vehicle. Hour-meters are activated to receive the GPS speed signal. This solution can operate the hour-meters without any connection to the vehicle harness.

LAPTIMES AND MAXIMUM SPEED DOWNLOAD TO USB PENDRIVE: The Stealth GPS-4 Lite has a wired USB socket that can be easily positioned into the fairing, you can plug any USB memory stick ti import data. This solution makes the system totally free from the computer, at the end of the track day you will just need to plug the USB pendrive and Stealth GPS-4 Lite will download the acquired laptimes and maximum speeds for each lap, that will be then analysed directly into the Digirace-MMX software.

999-LAP MEMORY WITH AUTOMATIC MANAGEMENT OF 99 TEST SESSIONS: The Stealth GPS-4 Lite will automatically create a new session whenever you access the track. This means that you can analyse the times you have stored during the various sessions even at the end of the day without having to delete memory whenever you access the track. You can store the date and time of every single session as well as the total time, the intermediates and the maximum speed for every single lap.

CYCLICAL MEMORY MANAGEMENT: With the Stealth GPS-4 Lite you will never face memory full issue; because in order to allow continuous usage, it manages the available space by erasing the oldest sessions automatically when the memory is almost full.

STORAGE OF THE FINISH LINE COORDINATES OF THE TRACKS MOST USED: You can store the coordinates acquired for the finish line of the tracks you are using most frequently. You can store up to 16 tracks and easily select the finish line of the current track without having to reset it every time.

STEALTH GPS-4 LITE IS COMPLETE WITH A BACKLIT LARGE-SIZE GRAPHICAL DISPLAY: This solution has provided the development of a software unit that can analyse all stored data and set up all required functions in a user-friendly and immediate manner. The display is transflective, which means maximum visibility also in the sunlight when the back-light is off.

EXTERNAL SUPPLY: Supplied with a 12V vehicle battery lead, you can hard-wire the unit to the bike; or you have the option of powering up the unit by purchasing a 9V external battery pack or Lithium-Ion battery. Moreover, the Stealth GPS-4 is complete with a powerful energy saving and self power-off function that the user can set up to make the best use of battery performance.

WATER-RESISTANCE: The Stealth GPS-4 is water resistant and can therefore be used in the wet.

Starlane S.R.L. were established in 1998 with the sole aim of developing innovative electronic products for motorcycle racing; their initial development projects being electronic systems for 2 stroke Grand Prix bikes. It was this testing ground that fuelled their creation of an engine management & data acquisition System, completely integrated inside the dashboard of the motorcycle. Such a solution had never been implemented before, even on the very best factory bikes, and it was soon after their implementation in 2000 that the racing results arrived. This in turn led to the very largest of bike factories opting for a very similar method, inevitably helping to forge Starlane's reputation, as a leader in performance electronics.
