I've been looking at them on e-bay.....so I sent the dealer a message asking how much one would cost if I didn't get the subscription..... I was told was told the subscription was only for watching / checking your times on an "I" phone or computer........
They messaged me back and said I needed a subscription to send the signal to the wire at the track........
Can someone with knowledge fill me in on the straight poop with these things.......Thanks for any accurate help !!!!
