Features to Look for Before Buying Caliper
Without the proper knowledge or idea on what factors make good digital calipers for reloading, you might end up with a product that will not perform the way you want it to, and it will just be a waste of time and money.
To help you in preventing that from happening, here are some points you should consider before you make your purchase.
Precision and Accuracy
Without a doubt, precision and accuracy are the most important factors to consider. This is why you are purchasing a caliper in the first place. For you to be able to take the measurement you need for reloading, your caliper should have an accuracy of 0.001 inches or 0.02 millimeters.
To get the best out of your digital caliper, it should feature different measuring modes. When reloading, you mainly measure your materials by millimeter, but sometimes, you also need to measure by fractions or inches. No one wants to take a pad or calculator and convert, right?
Quality of Materials Used and Overall Construction
You want your caliper to last you for years. This will be determined by what materials were used and how it was put together. Always choose a model that is made from top quality stainless steel.
One downside of digital calipers is that they need a source of energy to work. That said, look for a model that is equipped with long-lasting battery power. The last thing you want is to replace your battery every month or for it to stop working in the middle of your reloading activity.
Ease of Use
If you have decided to go for a digital scale, maybe it’s because you want something easy and quick to use. Look for a model that generates measurements quickly and has a large display that can easily be seen in a glance.
Digital Calipers vs. Dial Calipers for Reloading
Still, contemplating on whether to upgrade to digital calipers or not? For us, dial calipers are good, but considering digital caliper’s advantages, we’ll choose digital over dial calipers. Let us list them one by one.
Advantages of Digital Calipers
Much Easier to Use
They can show you the measurements in almost an instant. No need to read the small figures in the dial that can take too much time, especially for those with poor eyesight. It saves a lot of time, and of course, little to no effort is needed.
The large LCD screens that most models are equipped with are even bigger than your digital watch, so even those who don’t have a perfect vision can use it.
Another thing is that it’s very easy to convert measurements. Most digital calipers feature a button for this very purpose.
Very Easy to Calibrate
One of my favorite features of digital calipers is that you just need to press a button to zero it out. No need to perform any calibration! Talk about saving time!
Accuracy and Precision
Digital calipers are very sensitive and will offer you high accuracy readings. What’s more, do you know how hard it is to rely on a dial caliper’s measurement after it was accidentally dropped?
The rack and pinion on the inside will most likely be misaligned, making it difficult to calibrate.
Since digital calipers do not use the rack and pinion system, you don’t need to worry about it. We must say that digital calipers are shockproof in this case.
Disadvantages of Digital Calipers
Needs Battery to Work
Like any other product, digital calipers also have their cons. Although we must say that the only advantage of a dial over digital calipers is that they don’t use batteries.
No Weather Proofing
Unfortunately, they can be vulnerable to being destroyed when used in extreme weather conditions.
