Any disadvantage with older reels?

[Regor]

Hello all, First time poster here.

If an older reel (and gear) is still in good working condition, am I disadvantaged because I may not have some new technology?

Why? I was left my father-in-laws old gear when he passed 13 years ago. 4 tackle boxes full of gear, and an old 6-pack cooler with 4 reels stored in it.

I have used an abundance of the freshwater lures/etc over the years, but I am just now getting into fishing from the yak in Saltwater.
