PROBEROS Spherical soft baits are versatile

PROBEROS Spherical soft baits are versatile, durable silicone or plastic lures designed for slow-sinking or floating presentations, commonly used for trout and catfish in both fresh and saltwater. These flexible, often scented balls (8mm–14mm) attract fish through realistic, subtle movements, providing a high-visibility alternative to traditional baits. 
Key features of spherical soft baits include:
Action & Design: Designed to slowly sink, these baits enhance strike rates by mimicking natural bait drifting in the water column.
Material: Made from durable, flexible silicone or soft plastic that withstands multiple catches.
Attraction: Many, such as the floating ball baits found on Walmart, are infused with fish-attracting flavors.
Versatility: They are suitable for various rigs, including as a floating bait for trout or suspended catfish rigs, and are available in multiple sizes.
Alternatives: Specialized acoustic versions, such as Bayou Rattler SoNaR Ballzz on LandBigFish.com, feature inner chambers to create sound. 
These lures are popular for anglers needing a durable, scented, or high-visibility option, according to products sold on proberos.com
