How to Determine if a Golf Ball Is Good

By Spencer Lanoue

That golf ball you found in the woods might seem like a free treasure, but playing a questionable ball can absolutely sabotage a good round. A ball with even minor damage won’t fly correctly, costing you distance and accuracy. This guide will walk you through exactly how to determine if a golf ball - new, used, or found - is good enough for the course, using the same simple checks trusted by coaches and seasoned players.

The Essential Visual Inspection: First Clues to Performance

The first step is always a quick visual check. Your eyes can tell you a lot about a ball's history and its potential to perform. It only takes a few seconds, but it can save you from a shot that mysteriously sails offline. Look for these three main culprits.

1. Scuffs, Scrapes, and Deeper Cuts

This is the most common form of damage and arguably the one that has the biggest impact on ball flight. The dimple pattern on a golf ball is a masterpiece of aerodynamics, designed to reduce drag and create lift for a stable, penetrating flight. When you introduce a scuff or scrape, you disrupt that pattern.

What to look for:

  • Minor Scuffs: These are slight abrasions on the surface, often from hitting a cart path, tree, or a particularly sandy wedge shot. A light scuff may not be a round-breaker for a casual game, but anything significant will affect consistency. Think of a deep scuff as a tiny rudder or air brake on one side of the ball - it creates unbalanced airflow, which can lead to unpredictable hooks, slices, or a noticeably shorter, lower flight.
  • Deep Gouges or "Smiles": This is a clear deal-breaker. If a ball hits a rock or cart path forcefully, it can create a cut that looks like a caved-in "smile". A ball with a slice this deep is completely aerodynamically unstable. It will not fly true, period. Relegate this ball to the shag bag for chipping practice, or just throw it away.

The Coach's Advice: If you run a fingernail over the ball and it catches on a scrape, that scrape is significant enough to alter the ball’s flight. For your scorecard rounds, use a ball that is as smooth as possible.

2. Severe Discoloration

While a slightly off-white ball may not seem like a big deal, its color can be a strong indicator of its age and how it’s been stored. The cover of a golf ball, typically urethane or ionomer, will degrade over time when exposed to UV light and the elements.

A yellowed or brownish tint tells a story. It suggests the ball is either very old or has spent a great deal of time out in the sun. This exposure can make the cover material more brittle and less responsive. The feel off the clubface won't be as crisp, and you'll likely see a small reduction in spin and distance. More importantly, this is a major red flag for golf balls found in water.

3. Cracks and Dents

Unlike scuffs, which are on the surface, cracks and dents compromise the structural integrity of the entire ball. These are rare but are an immediate sign that the ball is done.

A crack can be a very faint line on the surface, but it runs deeper into the mantle or even the core. If you hit a cracked ball, the energy transfer will be completely inefficient, leading to a dead-feeling, low-launching shot that goes nowhere. An obvious a dent or flat spot means the ball is no longer round, and it’s impossible for it to roll or fly predictably. Any ball with a visible crack or dent belongs in the trash.

Beyond the Visuals: Simple Tests for Hidden Damage

Sometimes a ball looks perfect on the outside but is damaged on the inside. This is particularly common with water-logged balls or those that have suffered a major impact without showing an external crack. Here are a couple of brilliantly simple tests to uncover these hidden flaws.

The Saltwater Float Test for Balance

A golf ball needs to be perfectly balanced to roll true on the green and maintain a stable flight path. An imbalanced ball has a heavy side, which will cause it to wobble slightly during flight (costing distance) and, even more frustratingly, fall offline during the final few revolutions of a putt.

Here’s how to check a ball's balance:

  1. Find a clear container (like a glass or a jar) and fill it with warm water.
  2. Stir in salt until a brand-new, known-good golf ball just begins to float. Epsom salts work wonderfully here. This saline solution is dense enough to suspend the ball.
  3. Place your test ball into the solution and let it settle.
  4. Give the ball-a gentle spin or two and wait for it to stop moving.
  5. Observe which direction lands "up." A perfectly balanced ball will stop randomly, with no one side consistently facing up.
  6. If the ball repeatedly settles with the exact same spot pointing to the sky, it's out of balance. The heaviest part of the core has sunk a bottom, forcing the same light spot to the top every time. Mark the top "up" spot with a Sharpie and spin it again to confirm. If that dot comes back to the top, the ball是不好的练习。

This legendary test is the single best way to identify a ball with a compromised core, something you'd never be able to see optically.

The Bounce Test for Liveliness

The core of a golf ball is its engine. Over time and after many hard hits it can lose its "compression," or elasticity. A ball with a "dead" core won't rebound off the clubface with as much energy, which means less ball speed and less distance. A simple bounce test can reveal the state of a ball’s core.

  • How to do it: Take a brand-new golf ball (or one you know for a fact is good) and the ball you want to test. Stand over a hard, flat surface like a garage floor, patio, or tile. Hold both balls–one in each hand at shoulder height, and drop them simultaneously.
  • What to look for: Pay close attention to the height of the first bounce. A good ball will have a crisp, high bounce. A ball that is dead or water-logged will have a noticeably duller sound and a significantly lower bounce. If the test ball only bounces 70-80% as high as the good ball, its core has lost its life.

Understanding Golf Ball Lifespan: Are Water Balls a Good Deal?

A common question is, "How long does a golf ball actually last?” And what about those temptingly cheap bags of "refurbished" or "lake" balls? The truth is, while it might seem like a bargain, you're often paying for compromised performance.

How Many Hits Can a Modern Ball Take?

Today’s golf balls, especially those with durable urethane covers, are incredibly resilient. For the average golfer, a ball is truly usable until it's lost or gets a significant scuff or cut on the cover. Under normal play without major impacts (like hitting a cart path), a premium ball can easily last for several rounds - even 72 holes or more - without a substantial drop in performance. The key factor isn't a set number of hits, but the quality of those hits. A single shot thinned into a rocky creek bed can ruin a ball, while 50 perfectly struck iron shots might leave it looking pristine.

The Truth About "Water Balls" or "Lake Balls"

A golf ball sitting at the bottom of a pond is not in a preservative. While the cover of a ball is water-resistant, it isn't completely impermeable over long periods. Given enough time an - anywhere from a day or two onwards moisture will gradually seep through the cover and into the core.

This absorbed moisture does two bad things:

  1. It reduces COR: "Coefficient of Restitution", a fancy term for the ball's elasticity. A waterlogged core is essentially dead and doesn't compress and rebound efficiently, robbing you of significant distance. Those bounce and float tests? A water ball will often fail both miserably.
  2. It affects balance: Water may not seep in perfectly evenly, leading to the internal balance issues we discussed with the float test.

What about "refurbished" balls? "Refurbished," is a tricky term. Some companies simply clean lake balls and grade them. Others go a step further, stripping the original paint and logo and repainting them to look new. The problem is paint can hide serious scuffs and cuts, and it does absolutely nothing to fix a water-logged core. You might be hitting a premium-branded ball that has the performance of a wet sponge. It's almost always a better investment to buy a new, lower-priced model than to take a chance on a "premium refurbished" one.

Final Thoughts

Putting it all together, a good golf ball is one that is visibly clean of major scuffs and cuts, free of any cracks, and internally sound. Taking just a few moments to inspect your ball and occasionally testing suspicious ones can eliminate equipment as a variable, so you can focus on making a great swing and trust the result.
