RAC Plus I
...the standard in distance measuring instruments
The RAC Plus I brings the accuracy, reliability and productivity of using a vehicle installed distance measuring
instrument within the reach of everyone. All distance and speed information can be read directly from the RAC Plus I's
display - no software is required to view your data. This unit is a replacement for our older model RAC-100 DMI.
• Shallow Case Design
Light weight, high-impact ABS plastic case (7.8"W x 2.3"H x1.2"D) allows you to mount the DMI to the front of the dash
board or virtually anywhere inside the vehicle.
• Dual LED Displays
Dual 6-digit LED Displays are easy to read at any angle both day & night. The dual displays separate distance data
from speed, calibration number, vehicle number, time and menu selections.
• Four Brightness Levels
Select the level best suited for ambient light conditions.
• Menu Driven
Simplifies user selection for various operational capabilities.
• Automatic Calibration
Allows quick, simple calibration on all vehicles. Stores four separate vehicle calibration numbers for multi-vehicle usage.
• Extremely Accurate
Distance measurements accurate to 1 foot per mile, even at slow speeds.
• Change Distance
Pre-Distance if starting at a known point, count up/down or add/subtract distance from current display.
• Count & Display Hold
Freeze the display while continuing to accumulate distance with Display Hold or stop accumulation of distance
with Count Hold.
• Interval Distance
Display distance intervals between points of interest (i.e. Telephone Poles, Signs, Pavement, Markings, etc.)
• Distance Conversion
With a simple push of the Unit key, convert distance from Feet to Miles to Kilometers.
• Distance Pulse Output
Send calibrated distance pulses to a lap top computer or ancillary equipment. The interval and duration of the output signal are user selectable from
A power-on self test (POST) is performed each time the DMI is turned on. As part of the POST, the calibration number is displayed for your verification.

Vehicle Installed Distance Measuring Instruments
Accurate, reliable and easy to operate, our RAC units are THE BEST distance measuring instruments (DMIs) on the
market. These cost-effective units save time and money by allowing personnel to measure distance, accurate up to 1 foot
per mile, while driving as fast or slow as necessary. Results can be read directly off the DMI's display.
Much safer than the old 'Hand-Wheel', these units will pay for themselves in increased productivity in a matter of days.
Using either the RAC Geo's on-board GPS distance sensor, or an external Distance Sensor, the RAC DMIs provide you
with the best combination of accuracy and convenience.

RAC Geo II
...on-board GPS distance measuring, coordinates and data memory
The RAC Geo II takes all the benefits of the RAC Plus I and adds an on-board GPS receiver and data memory.
This allows for distance measuring without the need for an external sensor, and for data to be stored to the unit's
expansive memory for later download to a computer, creating an unparalleled combination of accuracy & convenience.
This cost-effective unit saves time & money by allowing personnel to measure distance, accurate up to 1 foot per mile,
while recording GPS coordinates of roadway features –
making it the most powerful DMI on the market.
Detailed analysis and reporting can be done by downloading to the RACPro software.
This unit is a replacement for our older model RAC Plus III and RAC-200 DMIs.
• GPS Distance Measuring
The RAC Geo II contains a built-in GPS receiver that can be used for distance measuring in place of an external sensor.
This reduces your overall cost since you don't have to buy an external sensor. The accuracy of the GPS distance
measuring is 1 foot per 1000, which is as good (and usually better)than an OBD plug-in sensor. Should you need the
greater accuracy of a magnetic or modular sensor (1 foot per mile), the Geo II does have the option to do distance
measuring with either of these external sensors.
The RAC Geo II will allow you to store up to 400,000 events in memory. Ideal for inventory applications, the Events are identified by using a four digit
numeric code (0 thru 9999) to identify signs, guide rail, pavement marking, intersections, railroad crossings or other highway features. Events are
stored in nonvolatile RAM (NVRAM). This NVRAM will hold your data for approximately 50 years, or until you clear the memory.
• Data Output
Download the stored data to your PC or laptop using our RACPro software. The downloaded data contains the memory location (0-3500), event code
(0-9999),distance, interval distance, time and speed for each event.
• Record Accurate Distances along with GPS Coordinates
Exclusive only with the RAC Geo II, you are able to store up to 30 hours of continuous GPS data, at one second intervals, while recording roadway
distance in the RAC Geo II's internal memory. Using this powerful inventory tool, you can record road features (intersections, bridges, signs, guide-rail,
etc.) along with their distance and GPS coordinates.
• Unmatched GPS Recording Accuracy
The RAC Geo II uses a GPS receiver which incorporates the Wide Area Augmentation System (WAAS) for improving accuracy of GPS signals. WAAS
uses a correction signal created by a collection of 25 land-based stations that are spread out across North America. This correction signal is then
broadcast from specialized communication satellites.
With WAAS enabled, our 12 channel GPS receiver capability allows 2D GPS accuracy of approximately 2 meters. Without WAAS, depending on the
location in the continental US and satellite accessibility, horizontal GPS accuracy is approximately 6 meters. This, along with the RAC Geo II's distance
accuracy of up to +/- 1 foot per mile provides unequaled data collection capabilities.
• Several Data Retrieval & Processing Options
There are two methods that can be used to retrieve distance and GPS information from the RAC Geo II.
In its most basic configuration, you can simply record and then read the distance and GPS information off of the RAC Geo II's display. This can be done
while the vehicle is stopped, or while it is moving, depending on the number of people doing the data collection.
Another method is to have the RAC Geo II store the events of interest, along with their distance, latitude & longitude, as you key them in. When using
this method, the GPS coordinates can be stored every second while roadway events, with their distance & latitude/longitude, are stored as you enter
them. This data can then be easily downloaded to the RACPro processing software for analysis, reporting or exporting to external software like Excel or
commercially available mapping programs.
