The new digital gold standard in weatherstations for professional and sportsman racers. The AltaCom 4xR is trailer-based, fan aspirated, remote sensing professional weatherstation with weather paging, weather texting, weather logging, live ET and TS predictions for drag racers, and extensive tools for improving your racing. Our Digital Sensor measures Temperature, Barometric Pressure, and RH, and converts that data into a digital signal. It also logs weather data on a regular basis for your convenience. Sensor data is captured by Merlin software, which calculates 8 values to give you a full range of information in your preferred format.

Merlin Weather Display
Merlin can display Current Readings updating every minute on screen. Merlin also can be set to show Trend Weather updating every 5 minutes and accumulating readings on screen. These data can be viewed as text, as a graph, and saved for later use, such as overlaying different days weather to anticipate daily trends.
Weather and Prediction Paging
One pager comes standard with the 4xR. Additional pagers can be programmed to match. Weather variables can be selected to show/not show in the pager to simplify the data you see in each transmission. Up to 5 separate ET and or TS predictions can be created and transmitted with weather information. Merlin has powerful tools for ET and TS Prediction. Manage multiple users, fuel and jetting changes, reveal mechanical inconsistencies, spot bogus runs, refine predictions and more.
Weather and Prediction Texting
If you have a hotspot at the track, Merlin with the 4xR can text and email weather and predictions to your smartphone.
