Dragy works great and accurate...so I'm told. The problem w/ using one on a back road is traction.

as it seems to be semi-affordable to me, i might just give it a try.
if i go that route, i will certainly report back.
i may have a passenger along just to monitor the device, as i firmly believe in concentrating solely on the chore at hand.

You don't have to monitor anything. You just drive. It starts and stops every time you do and records it to your history. As far as accuracy, I've taken mine to the track and compared it to the time slip. 330 was the same 660 same 1000 same 1320 same , ets and mph. 60 ft showed .004 slower on Dragy. I love mine. A couple of times I've had a little trouble getting it to connect to the phone. Otherwise , no issues.

I bought a draggy last year to use on a (mid 13.s in the 1/4 mile) bracket car I bought to teach my youngest granddaughter and her Husband to learn how to do and understand drag racing. I had heard great things about all 3 versions of that unit She got pregnant so no racing for her for a while
I will use it on my new drag car next summer after it is done
It should be way faster than any of my old cars, hopefully in the mid to low 4.0 or quicker in the 1/8 mile

i pulled the trigger for one yesterday, so i'll see how it works out.
however, now i need to figure out the "smarter than me phone" i haven't got out of the box yet, so i can use the dragy.

Just ask your 12 year old grand-daughter to show you how to do it.

Me too

unfortunately, she is many states away, and if i would approach a girl of that age around here, she would take one look at me and call the police !

Follow the directions. You'll get it. Easy peesy.
