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 f
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 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. 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. 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

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
I've heard mixed reviews about these but I played around with one at a race a few weeks back and it seemed great. So I got one. And its surprisingly good. It seems some have range issues with theirs but I do not. Right out of the box on a half charged battery I was able to maintain connection and count laps at 60 yards. I actually purchased an external antenna and built a mount to maximize range, but it seems to have plenty of range without them. And its super cool. I connected it to my phone, then connected my phone to a bluetooth speaker and it calls out laptimes loudly over the speaker just like a real race. Even says my name. You definitely need a lap timer to push yourself when you practice. I'm super happy with this one. I don't deny anyone else's experience with it, but my experience has been great. Definitely get one of these if you're thinking about it. I love it!
I expected a useful lap-timer based on his well-known brand. When I synced, the distance (Bluetooth) that works is like 4 or 5 meters no more than that, for that reason I think is useless because you probably lay down the gadget in gate 1, and the spot where you flight - for sure - is more far away. The app is really clumsy and no polished.
