If you’ve ever shopped for a fly reel and wondered why one costs $200 and the other $700—even though they look pretty similar—you’re not alone. One of the biggest factors in that price gap comes down to the construction of the reel; it’s either cast or machined. So what does that actually mean, and does it really matter? Let’s break it down.

Cast Fly Reels

Cast reels are made by pouring molten aluminum into a mold. It’s a quicker and more affordable way to produce reels, which is why you’ll see cast models at lower price points. Plenty of reputable brands like Redington, Sage, & Lamson make solid cast reels that work great for everyday fishing, especially in freshwater.

The downside? Cast reels are not as durable as their machined counterparts. If you drop your reel on a rock or hard ground, there’s a higher chance it cracks or bends. They’re also a little heavier, and because of how they’re made, they can’t be quite as precisely engineered as machined reels.

Machined Fly Reels

Machined reels start as a solid block of aluminum that gets carved into shape using a CNC machine. It’s a slow, exact process, but the result is a reel that’s lighter, stronger, and built with tighter tolerances. These reels tend to feel more refined and usually hold up better in the long run, especially in saltwater or rugged environments.

If you’re traveling, fishing hard, or putting your gear through hell, that extra durability can be worth the higher price.

So… Which Should You Get?

Here’s the simple answer:

If you’re new to fly fishing, or mostly fish for trout in freshwater, a cast reel is probably all you need.

If you fish a lot, target bigger species, or spend time on saltwater, a machined reel is absolutely worth the extra money.

At the end of the day, it’s about matching your gear to how and where you fish. Cast reels are great for getting started or building a backup setup. Machined reels are what you want when reliability and toughness matter most.
