I actually sign all my Pro V1's with my signature. I figure it will be a unique marking that nobody else will have.

I'm amazed at how many people do not mark their balls, I see it virtually every weekend where someone accidentally plays someone else's ball b/c they're unmarked.

I've always marked mine the same, 3 black dots around the ProV1x red number on both sides of the ball. I've never had an issue with someone trying to play mine.

Two black dots either side of the number for me.

Very simple, very quick to draw on

I either order mine customized with the #72 & Jarhead on them or if I have to buy some off the shelf I put a line on them. I’m typically the only one in my group playing a ProV1

I play ball #8 a put three blue dots beside it. Simple and clean.

I use my father's initials. When I get a HIO will burry it next to him. RIP!

I get mine stamped with my initials in blue. I usually add a blue line for putting. Not necessarily unique but gets the job done.

I like keeping my pro v1 clear of markings. I feel like it’s one less thing to be distracted by when hitting.

1 dot under the number on the ball. Usually green.

Navy blue lines and dots!

3 red dots just under the numbers.

I put a red dot both sides of the Titleist word

I use the pro v wording to line my putt up

Hahaha, I use a red dot and a black line with arrows at the ends!!

Seriously (and I hope everyone picked up on my attempt at humor!), blue dot left and slightly below the number and a red dot right and slightly below the number, both in dimples, plus a black line across the parting wave seam on the high side of the ball (hold the ball so you are looking at the Titleist logo; the black line is across the upper half of the parting wave seam).

Usually I either underline the capital "T" in Titleist or put a cross over the "T" in Titleist.

After an eventful weekend i've decided to start marking my ball. I was always too OCD to do this but lets just say I had a heated discussion with a mate.

After hitting a super clean drive, over the trees we couldn't find my ball so I played another. Walking up to the green I found my original ball in the bunker which was about 351 yards. He didn't believe it went that far so now we don't have to argue anymore.

I bought a $12 ball marker with a bunch of accessories off Amazon which I got today. Just doing the normal putting lines like Cam Smith etc use.

I just put "red dots" on both sides of the ProV1 number, but I have a friend that writes "not your ball" on his which is hilarious when he loses one.

I use a stamp to mark mine with my initials.. never seen anyone else with it so its certainly unique

Custom # + Daughters initials for ball customization. Keeps it pretty unique.

I’ve only ever seen another player match my marking one time. Oddly enough it was a srxn Tri-something about a dozen years ago and we both drew green shamrocks on the same ball. I tried not marking a custom number ball, but some haughty member at a club I had just joined chewed me out for not marking a number 50 ball. Seriously…
I now just add 1 green dot and 1 red dot, and carry one ball with just a green dot should I need a provisional. Too often the provisional will track to the first.

Depends...if anyone in my group is using a ProV1 with my number and then I will mark it with a red dot on the right side of the number. Other than that, I don't mark my ball.
