The Trident Align Full Metal Solo is the all-metal Trident Align ball marker on its own, $19.99 direct or $18.99 on Amazon. If you already putt with a line on your ball, I like it. If you don’t, you’re paying twenty bucks for a coin.
Is the Trident Align Full Metal Solo worth buying?
Here’s how most of us line up a putt. You draw a line on the ball, you read the break, then you crouch behind it and spin the ball until the line looks right. Looks right. That’s the problem. You’re eyeballing it.
Trident’s fix is a top plate that swivels on the marker. You point the plate at your start line, set the ball down, and turn the ball until its line matches the edge of the plate. So instead of guessing, you’re matching the line to something.
The Full Metal is the premium version of that idea, with a metal base and a metal aim finder. The Solo is the cheapest way into the metal one, because you’re only paying for the marker.
Quick Overview
- It’s $19.99 at Trident and $18.99 on Amazon, and Black is the only color in stock.
- The aim finder swivels 20 degrees left and 20 degrees right without moving the base.
- The base and the aim finder are both metal. The cheaper 2.0 uses a plastic top plate.
- It’s 1.38 inches wide and 1.50 inches long, so it’s a lot bigger than a coin.
- If you buy direct, Trident gives you 30 days to send it back.

The Trident Align Ball Marker Gives Your Line Something to Match
This is the whole reason the Trident exists, so let’s start here.
A line on the ball only helps if it’s pointed where you want the putt to start. And pointing it by eye is harder than it sounds. You’re lining up a skinny line on a round ball from five feet above it. Be a little off at the ball and you’re a lot more off by the time it gets to the hole.
The Trident gives you an edge to work with. You read the putt, turn the aim finder until it points at your start line, then roll the ball until the line on it sits flush with the finder. It’s a physical match instead of a guess. And because Trident sets the center line at 90 degrees, the line on your ball shouldn’t sit tilted left or right either.
Here’s the thing, though. It doesn’t read the putt for you. Pick the wrong line and the Trident just helps you start it perfectly on the wrong line. So this is for the golfer who can read a green and keeps missing because the ball wasn’t aimed where he thought it was.

Metal Is What You’re Paying Extra For Over the 2.0
Trident makes a cheaper version, the 2.0 Solo. Same idea, same swivel. The difference is the top plate. On the 2.0 it’s hard plastic. On the Full Metal it’s metal, and so is the base.
That costs you $3 at Trident, $19.99 against $16.99. On Amazon the gap is $4, $18.99 against $14.99.
So is metal worth three or four bucks? If you already know you’re going to use this thing every round, yeah, I’d pay it. Trident’s pitch for metal is that the extra weight keeps it steadier on the green, and the aim finder is the part you’ll be twisting on every hole. There are also two little studs on the base to help it grip on hard, fast greens.
But if you’re just curious whether a line-matching marker fits your routine, start with the 2.0. It’s the cheaper way to find out.
Whether You Own a Stencil Decides Solo or Kit
This is where people waste money. To use the Solo, you need a straight line on your ball.
If you already have a stencil, great. Buy the Solo and you’re done for $19.99.
If you don’t, let’s do the math. Trident’s stencil tool is $9.99. Add that to the Solo and you’re at $29.98, and you still need a pen. The Full Metal Kit is $34.99 and comes with the same marker, the stencil, a Sharpie and a pouch. So for about five bucks more, you get the whole setup. Get the Kit.
A generic stencil runs about $5 or $6 on Amazon, and the Solo works fine with one of those too. My guide to golf ball stamps and marking tools covers a few.
And if you don’t putt with a line at all? You don’t need any of this. A flat marker does the job. My own brand, MagnetOwl, makes a magnetic ball marker for $4.95, so yes, I’m biased there. But honestly, the coin in your pocket works too. The Trident is only worth $15 more than a plain marker if you’re going to use the aim finder.
If you’re all in on putting with a line, Trident builds more gear around it. I break down their practice ball in my Tri-Roll Tour golf ball review and their mirror in my Transform putting mirror review.
What I Don’t Love
I haven’t seen a single controlled test proving it holes more putts. And Amazon has it at 3.9 stars on just 11 ratings. That’s not a lot to go on for a product that’s been around since about 2021.
It’s also big for a marker at 1.38 by 1.50 inches. If it’s anywhere near somebody’s line, swap it for a flat coin. A putt rolling into a chunk of metal that size isn’t going anywhere good.
And it adds steps. You mark the ball, set the finder, turn the ball, then pick the marker back up. If you like to walk up and hit it, you’ll probably quit using it by the back nine.
Who It’s For
Buy it if:
- You already draw a line on your ball and use it on every putt.
- You can read a green, but your putts keep starting off your line.
- You already own a stencil and just need the marker.
- You want the metal version and don’t mind paying $3 or $4 more than the 2.0.
Skip it if:
- You don’t putt with a line. A coin, or a $4.95 MagnetOwl, does the job.
- You don’t own a stencil. The $34.99 Kit is the easy way in.
- You want the quickest routine on the green.

Frequently Asked Questions
How do you use the Trident Align ball marker?
Put it down behind your ball like any marker. Read the putt, turn the aim finder until it points at your start line, then set the ball back down and turn it until the line on the ball sits flush with the finder. Pick up the marker and putt.
Is the Trident Align ball marker legal?
Trident says it conforms to the Rules of Golf. I haven’t seen the USGA’s ruling on it myself, so if you’re playing a tournament, check with the committee before you use it. If you’re fuzzy on the basics, here’s my rundown on what a ball marker is and why it matters.
What’s the difference between the Trident Align Full Metal and the 2.0?
The top plate. The Full Metal has a metal base and a metal aim finder. The 2.0 has a hard plastic top plate and costs $16.99 at Trident, $3 less. The swivel works the same way on both.
Does the Trident Align Full Metal Solo come with a stencil?
No. The Solo is just the marker. If you need a stencil, Trident sells one for $9.99, or you can get the $34.99 Full Metal Kit, which comes with the stencil, a Sharpie and a pouch.
