The 2015 and 2016 are the same current model, introduced in 2015. The arrowhead itself is separate from the short alignment line on each side, and the lines/arrowheads are gray, not black. The Pro V1 lettering is in black.

On the previous model (2013/14) the alignment line/arrow was also in gray, but the line and arrowhead were not separated by any space.

Hi,

I normally play with DT solos. However I was given a Velocity and decided to make it my ball of choice for teeing off a once in a lifetime family golf game at the Old Course, St Andrews. I’m off 22 and shot a 91. Net 69. A lifetime best (at 66 years old). It’s a Velocity numbered 00 in orange numbering. How can I find what year the ball is from? Is it 2016 or 2018. I’ve kept it as a souvenir but would like to buy some similar.

The side stamp changes every two years. It looks like the 2019 ball will have the 2017 side stamp, but in gray.

lot of times if someone playing same ball ass me. I will put a black dot near the number. but I like to draw a line over the model of ball ik playing since lot of my friends dont use a line while putting.

Here is a link that shows the years and Pro V1 and V1x models.
