Tim Healy's Review of the Velocitek Shift
We really like the Shift. In the J/70 we use the option to keep track of the upwind angles. It's really nice feature. It gives you up and down readings tack-to-tack, and you can reset it anytime.
In the J/24 we don’t use the shift tracking. The compass is easy to read - big display, and simple design. I was driving the boat in Ireland (Worlds 2013) and could see it easily. I was doing tactics for John Mollicone at the NAs and I was substantially further forward in the boat; I could still read the compass easily.
In Newport there was really steep chop, the bow was coming up and down and here (J/70 NAs in Annapolis) it has been smoother water. It worked well in both sea states.
