To get a sight line added you would need to send your putter to the Scotty Cameron Custom shop. Cost of adding the line is $30, but there may be some additional costs that I'm not aware of. You should go to the Scotty Cameron website and go to the Custom Shop page.

Alan, The SC Custom Shop is the only vehicle to have this done via Titleist that I am aware of at the moment. The first sightline is $30 and additional lines are $10 more each. I would consider having some other custom options done at the same time due to the time and expense you will go through to have this done!

Good Luck!

Minimum cost is $45 to handle shipping and return services. So you may want to add a new paint job, or order a new colorful grip, etc., as well.

If you don't want to send your putter into the CS, you can do it yourself with pinstripe tape
