ImmersionRC LapRF Personal Race Timing System

The LapRF is a personal race timing system for FPV quads using 5.8GHz video feeds.
The passing of a quad through the start/finish gate is precisely measured using the energy emitted by the 5.8GHz transmitter on the quad.
Custom fully-programmable timing receivers, coupled with ImmersionRC's timing antennas ensure that the performance of this system is on a different level than competing products. Video power levels from 10mW through 600mW supported.
Super-precise with one pilot, but also supporting multiple pilots for smaller events without purchasing multiple units (up to 8 with lower gate speeds as found in the micro-quad world).
Bluetooth connection to Android and iOS devices, with free applications downloadable from their respective app. stores.
Fully integrated with the industry standard LiveTime event management software. Integrated 2600mAh Li-ion battery, with integrated USB charger gives 8 hour race time.

Features:
1.Easy To Use
It doesn’t get much easier. Power on the LapRF, drop it in the start/finish gate,
select its ID in the free Android/iOS app, select the number of pilots, and video channels used, and start racing.
The LapRF will run all day, measuring lap times and speaking the results. There is no better tool to allow pilots to measure their performance, and work to improve it

2.No More Transponders
The lapRF uses the Radio Frequency energy emitted by the Video Transmitter on the model to detect its presence within the race gate.
The current generation of racing drones have two things in common, they all use 5.8GHz video downlinks, and they all need to be on different channels to race together. This is all that the lapRF system needs to precisely time events.
No RFID transponders, no Infra-Red transponders, no complex installations. Just place the lapRF system in the start/finish gate, and start racing.

3.Bluetooth Link to Phones and Tablets
The LapRF Personal Timing System includes a bluetooth module which can quickly link an iOS or Android device to the gate.
Enter pilot names, start the race, and the lap times will be spoken along with the pilot’s name.
All lap times will be shown in a table, along with average, and best lap times.
Any loss of Bluetooth connection will not result in loss of lap times. When Bluetooth is reconnected, all missed lap times will be transferred to the app.

4.Personal… but Sharable
The LapRF Personal Timer was designed to be used by one pilot, that is where it is the most precise. But if you want to invite a few friends along for a quick race around the park, we support that too, out of the box.
No need to figure out how to interface your mates timers together, or run multiple apps, just share yours.
Timing resolution (which is more than enough with one pilot) decreases as you add more pilots, but when you start with more than enough, and share, you end up with just enough
