Clear, bright red LED displays
In baja or offroad rallies, it is important not only to measure distances accurately. W he appropriate presentation of the measured values is essential. The display should provide visibility during the day and at night. When driving on uneven terrain, the readability significantly decreases, small signs blur.
The 4×4 H-101 metrometer has three independent display sections with a digit height of 14 mm. The red color provides excellent readability of the measured parameters. Many pilots (they’re the ones who use 4×4 metrometers) find the red displays most readable. Adequate red color, high brightness and considerable dimensions allow you to take readings even while driving in the wilderness. You can decide for yourself the parameters displayed in each section of the display. As befits a real off-road metrometer, the display is protected by a film to protect it from moisture and dirt.
The metrometer has a backlight brightness control, which allows you to adjust the brightness of the metrometer screen to outdoor conditions.
The metrometer’s buttons have backlighting to help you work on the metrometer at night. Along with the displays, the backlighting of the buttons is adjustable.
Quick long ODO correction for off-road rally computers
The rally computer features a useful long ODO distance correction function. Should the measured distance not align with the distance provided by the organizer, you can perform a quick correction using the arrow buttons. Each press adjusts the correction value by 10 m.
Holding down the button will repeat the correction.
Alternatively, you can perform a full long ODO distance correction by manually entering the value into the rally computer.
Resistance of the metrometer to external factors
The presented model is characterized by exceptional durability, which is not provided by other devices, such as Terratrip metrometer or Monit metrometer. Off Road Rallies is an environment in which “metrometers” can suffer serious failures. When driving on unpaved roads and in inclement weather, you expose the metrometer to great challenges, but the H-101 will not be impressed.
The iTrip H-101 metrometer’s resilience is due to its good quality materials and proper construction. The outer casing is made of steel, and the individual parts are welded – so the structure has the right rigidity. Tightness is ensured by double seals made of two different materials. There is no question either of mechanical damage or of dust or water getting inside. Off Road rallies are very demanding in this respect, but the H-101 metrometer will cope flawlessly – nothing will disturb its operation during the ride.
Azimuth routing function or “azimuth driving”
The metrometer can be equipped with an “azimuth driving” function. This involves piloting the rider through a metrometer, to a point that is specified in the roadbook using the course and distance to the destination. Metrometer for piloting indications of the direction to the target, the distance to the target, and the course to the target expressed on the display as direction.
The metrometer can display the course to the destination on the connected Garmin device which then works as an external display .
You can enter the waypoint routing data before the start of the rally / stage. You can do it with the buttons of the metrometer or upload with a flash drive a file prepared on your computer.
Waypoint routing is done in a fraction of a second. There is no need to stop or reduce speed during the moment of routing.
Built-in GPS module in the metrometer
The metrometer can have a built-in ultra-fast GPS module to enhance the functionality of the 4×4 metrometer. The GPS module is responsible for supporting the road measurements or is completely responsible for the measurements. By using GPS exclusively, you exclude the need for speed sensors.
When installing a metrometer, you can choose the best option for you. You can completely dispense with sensors, or choose a solution in which you have sensors mounted and a built-in GPS module. This solution gives you a choice during any situation you experience during the rally.
When using measurement using only GPS data, there is no need to calibrate the metrometer.
Time and Distance Control from TC to TC
The H-101 rally computer for 4x4s features a function that allows you to monitor time from TC to TC. You can also track the ODO (TOTAL) distance. When starting from a TC, input the time and distance to the next TC. This data is provided on your time card and in the roadbook. During a single rally section, between TCs, you can repeatedly activate measurement modes. The rally computer will continuously monitor the elapsed time and distance to the next TC.
Emergency switchover to count the distance traveled from GPS
Rallies held on unpaved roads are more demanding, so the driver and pilot should be prepared for any eventuality – including major breakdowns. The H-101, an advanced off-road metrometer, has a function for emergency switching of road calculation to GPS data. Without using the configuration menu, you can switch the metrometer to counting from GPS. This situation can occur in case of failure of the measurement sensors. After switching, the road measurements will continue from the values that were measured until the sensors failed.
GPS-based metrometer time synchronization (H-101 metrometer with GPS)
A clock synchronization function is built into the metrometer with GPS module. With this solution, the time is automatically synchronized with GPS time.
Configuration of measurement parameters
You can adjust the H-101 metrometer to your preferences. The metrometer has a function that allows you to set the parameters that will appear when each measurement mode is activated.
Precise measurements from speed sensors
The iTrip metrometer allows connection of 2 speed sensors of any type. The sensor signal can be used in 3 ways:
- works one input with one way sensor
- works one input with one way sensor, a backup sensor is connected to the second input to make a change in case of failure
- two inputs with two sensors work simultaneously. The metrometer takes simultaneous measurements from two sensors mounted on the right and left sides of the vehicle.
How to connect the H-101 4×4 rally computer to a car?
In the Support section, we provide a user manual and connection instructions for the rally computer. It contains a description of all functions, a wiring diagram for the rally computer, installation method, and much additional information.
In brief, to connect the rally computer, please:
- connect the ground to the brown wire and the positive power supply to the red and yellow wires (from 10 V to 30 V). For the GPS rally computer version, this is sufficient for operation.
- connect the speed signal from the sensor to the white wire. Perform calibration. The rally computer will operate independently of GPS.
Full Speed Sensor Operation Control
All iTrip tripmeters feature a speed sensor failure warning system. Each sensor is associated with a two-color LED on the front panel. This LED indicates the sensors’ operation and activity. A red LED signal indicating a loss of speed signal while the vehicle is in motion indicates:
- impending problems with the speed sensor
- errors in matching the speed sensor type to the tripmeter.
Sensor monitoring is performed continuously. No other tripmeters possess such features. This functionality is absent in Monit and Terratrip tripmeters, and was not present in the 4×4 Explona tripmeter.
What is the price of a 4×4 rally computer with the features of the H-101?
A 4×4 rally computer, such as the H-101, which is durable, sealed, and functional, costs from 1,500 PLN to 3,000 PLN, depending on the version. The price should be weighed against the benefits:
- the rally computer is durable and will last a long time
- the rally computer is reliable, meaning, for instance, that its failure will not lead to a poor start or withdrawal from a rally
- it comes with support and a 5-year warranty
Considering the benefits, the price of a rally computer used for several or more years seems low. We are talking about annual costs of 200–400 PLN, which are negligible when competing during the season. We know this because we also participate in rallies.
As the manufacturer, we welcome customer inquiries. The overarching idea during design was to provide users with a rally computer that ‘just works.’ iTrip rally computers are not toys; they are professional tools. They must work. If they don’t, we will help find the cause and ensure stable measurements under all conditions.
Three resolution options for measured distance and ODO correction
Each off-road rally computer we produce displays short distance (TRIP) and long distance (ODO) measurements in one of three resolutions, selected by the competitor using the rally computer.
- TRIP distance: 1 m, ODO distance: 1 m
- TRIP distance: 10 m, ODO distance: 10 m
- TRIP distance: 10 m, ODO distance: 100 m
The ODO distance display resolution also affects its correction value.
- ODO distance: 1 m, correction: +/-1 m (each press of the correction button)
- ODO distance: 10 m, correction: +/-10 m (each press of the correction button)
- ODO distance: 100 m, correction: +/-100 m (each press of the correction button)
Trip Meter Application in 4×4 Rallies
Cars, custom vehicles, trucks, SSVs. For motorcycles, we recommend the H-51 motorcycle trip meter. For classic cars, we recommend the i-102 or Classic.
Reversing Distance Calculation Direction
The reverse counting mode enables distance measurement in the opposite direction, effectively counting the distance backward. In practice, this function can be used, for example, if you get lost. When returning to the point where you got lost, activate the reverse counting function. The distance measured by the tripmeter will not include the distance traveled on the incorrect route.
You can activate this function using a switch connected to one of the harness wires labeled: Reverse Drive.
Competition for iTrip Rally Computers
In the realm of 4×4 rally computers, or off-road odometers, the H series stands unrivaled. This product is specifically designed for off-road use, challenging terrains, and all forms of 4×4 applications. We are familiar with rally computers from other manufacturers. However, devices like Terratrip and Monit odometers are not particularly suited for 4×4 use. Furthermore, there are various domestic products sold on Allegro, which we do not recommend for such applications.
Working with external reset buttons
The rally computer can operate with external reset buttons. It also works correctly with an external, sealed remote control. In many situations, operation via an external button is faster and prevents errors caused by accidental presses of incorrect buttons.
The remote control can be a three-button version, which allows for: resetting the short TRIP distance, and adjusting the ODO ‘up’ and ‘down’ by a set value. A single reset button only allows for resetting the short TRIP distance.
Working with a Garmin add-on device
When you use the waypoint routing function, you can use the Garmin as an additional display. The Garmin along with the route to the waypoint displayed on the map will make the route clear as never before.
Stable 4×4 Odometer Mount
The H-101 odometer, also known as the 4×4 odometer, can be securely mounted anywhere in a car, truck, or SSV. It features 8 built-in M4 threaded mounting points, guaranteeing the odometer remains firmly attached to the vehicle during driving.
