Power Hobby PHGSM020 GPS + GLONASS Performance Analyzer Bluetooth Speed Meter & Data Logger

This version is awesome and easy to use any of the tracking or telemetry features. The drag and tracking work great for boats.

I have tested accuracy against other similar devices and cellphone apps, accuracy is acceptable for what I need to know, it is not a lab precision instrument.I’ve attached a couple of pictures of what information you’ll get on a track and flying test, and that’s it, don’t expect any kind of logs files, charts of any other information.Ease to use, just follow instructions.

I originally bought this for my drag car, but also decided to put on my 1/10 scale on road car to test different performance changes and this is very easy to use and you can fit them anywhere on the car. I wish I would of had one earlier. Great tool to enhance changes on your cars.

Edit I am too impatient, device probably would’ve worked properly if I read any instructions. I am leaving my initial review to help people understand it is not the product, it’s you!Let it connect to the satellites before installing on the RC!(Loses Bluetooth connectivity within 10 ft, rarely finds satellites)

Small, simple to use, and accurate. I set it up on the dash in my car, and matched it to my car’s Speedo. It’s accurate. Battery life is good, it works well in my RC cars and boats.Definitely recommend it, if you are trying to accurately determine speed, especially in hobby vehicles, it simply works.

These seem to be the standard when used for RC speed runs but I find the software awkward where you have to do a start-stop-read just to zero out and then do a start again to start logging.I switched back to my stand alone unit because I was using my phone to record video and found it cumbersome to go back and forth between apps.It's a good unit but just not for me.

Amazing

It rarely connects, when it does it works as expected but it never wants to connect. I have tried to use it many times in many different places and it rarely works. Even if I go back to the same place it worked one day it wont work the next. I'll be purchasing another GPS to test my speed with. This one isn't worth the money.
