The 100LX/DC3 is Hollis’s entry point into its “LX” line, built to give divers the same sealed DC3 first stage used across the brand’s higher combos while keeping cost down with a simpler second stage. It’s a common recommendation for new divers who want a sealed reg without paying for a fully adjustable second stage they may not need yet.
