XFR Adapter, Black, V3 or Sporter Chronographs

I saw the reviews that the app doesnt work, took a chance and got the thing anyway. Everything works just fine. I guess the app is fixed now or it just works with my phone.

Small and compact. Easy to plug in and to download the recorded shots.

I use it for my speedo chronograph

I was debating selling my magnetospeed sporter and getting a V3 but after getting this adapter, there is no need to. I'm running this on a Samsung Galaxy S7 and it works perfectly. This allows you to run the magnetospeed app on your phone which streamlines reading the data off of the sporter. You can save your strings on your phone and you no longer have to hit the buttons on the chronograph going through the data of your shot strings. Just plug this into your phone, and the data is downloaded in seconds. The app also allows you to make changes to the chronograph much easier than it is using the chrono itself. I would highly recommend this as a add on to the sporter. Totally changes how user friendly the chrono is.

For all the people that can't seem to get it working I did notice I had to take my phone case off. Magnetospeed gives you an extra long 3.5 Jack but it wasn't long enough. Make sure you plug the brick part of the device into your phone and not the Magneto speed "computer". You also need to make sure that you're up to the latest version on your Magneto speed "computer" (2.1.04)and the app for that matter. I have a Samsung Galaxy S8 and everything's working just fine. Although I do think this device is a little overpriced for what it does but so is everything from magnetospeed.

I spent the $25.00 for this and totally wasted my money. When I tried to call Magneto Speed support, there was of course, no one home.It simply doesn't work.

This works great and does exactly what it says it does, displays shot info on your phone via the app...that said I rarely use it. I purchased the Sporter and because of the smaller display I thought I needed the XFR to view all the data but the Sporter display has all of the same info on it and it's easy to cycle thru to get your Average, Standard Deviation, Extreme Spread and each individual shot data in your group just by pressing the button you cycle thru this data. The XFR works great if you want to use your phone to view the data though, all on one screen but you do have to unplug it from the MagSpeed and plug into your phone to view each shot series so consider if that's what you want to do!

Unit seems as described and recognized my iPhone SE v1 but could not transfer data to the phone.Cannot give a full review but be aware of iPhone compatibility with the unit.
