I just bought the digicue blue (dcb) which arrived yesterday, so I have about 2 hours on it. So far, so good - I like it. Setting it up was fairly straight forward. I do recommend watching the youtube video on how to get the device into the silicone sleeve as it makes it easy. The new dcb in my opinion is a better choice because you get to see what the device detected as a fault versus just getting a buzz and not knowing what for.
The dcb measures the following:
1. finish - time you stay still
2. finesse - speed / power (off by default)
3. straightness
4. tip steer
5. follow through - smoothness/acceleration
6. jab - deceleration
7. backstroke pause (off by default)
8. shot interval (off by default)
There are 4 modes, beginner-intermediate-advanced-custom. I started out with the beginner mode which only had 1-3-4-5-6 in use, finesse/pause/shot-interval are off. I guess I was within the tolerance levels so the dcb hardly buzzed. Right now I'm on the intermediate setting. Suffice to say, my flaws are showing. The dcb is buzzing quite often, lol. The same monitors are used (1-3-4-5-6) but the levels are up a notch in the app/menu system. For example, on finish you had to stay still for 1sec in beginner mode, intermediate mode is 1.5s, advanced 2s.
Personal opinion / review:
I have a home table and not really into performing drills. I just spread 10balls out and go at it. Initially I was looking at the phone after each shot to see what was the issue and try to adjust. After awhile when I got the idea of how to keep the dcb silent, I'll just keep going without reaching for the phone regardless of result. I'm using every ounce of will power to follow-through and stay still for 1.5sec. I have to adjust my stance which affects my view / alignment, all that, because if I didn't - it was not easy to stay still. I had a tendency to pop-up or move my bridge, still do, but it's work in progress.
It is a good aide for me, so I'm a believer.
