Machined reels are milled out of a solid block of metal. This process leads to a lighter and stronger reel; machined reels will last a lifetime and offer the best performance over time; not surprisingly, they are also more expensive than pre-cast reels.
Another thing to consider is the finish on the reel. An anodized finish will stand up to salt water, which is very corrosive, and this is essential if you’re planning on fishing in the ocean.
