TFS is a great addition. I had a retraction issue with my unit. About 50% of the time, the tether will not retract causing my cart to keep moving even after I stopped. I'm waiting for resolution from alphard.
I was a bit skeptical at first...the idea of a physical tether reminded me of my leashed dog. In this case who (or what) was going for a walk? After multiple rounds with the TFS, it has completely changed my perception of how a "remote" cart can function. The TFS is so good that I completed a whole round with just the TFS and no remote (accidentally left at home) and no issues. With the TFS addition, golf for me is truly a nice stroll...golf as it was meant to be.
I was a tester for the V2 and TFS, and I was not sure about the whole "Tethered" part of the follow system. Alex said "just try it". Yep. That's all it took, even with the early test unit, it just took a couple holes and I was sold! Not only are you more sure of where the cart is behind you, but the tether actually makes using it more intuitive. Other systems you have to press stop and go on the remote to have it follow, or use some other method. With the TFS, it is take the tether and it starts following you, and retract and release the tether as you arrive at your shot and go for a club and it stays in place until you want it to go again. The pull from the tether is less than a pound of pressure, you don't feel it pulling against you. It really adds to the enjoyment of playing and walking.
