What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
The largest common ocean drum size. Longer bead travel means a deeper, slower wave sound but two hands to control it.
Detail 02
Shallow enough that beads stay in one plane, so tilting produces a smooth continuous sweep instead of rattling.
Detail 03
You watch the beads move as you tilt, which makes it easy to learn and useful for teaching and therapy.
Detail 04
Heavier than plastic pellets, so the wave sound is denser and carries further at low volume.
Detail 05
The opposite head can be struck like a frame drum for thunder hits between wave sweeps.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Hold it flat and tilt in slow circles so the beads roll across the head. Speed and angle change the wave from gentle surf to a heavy crash. You can also strike the head.
It is the largest standard size. Bigger means a deeper, longer wave, but you need both hands and a place to set it down between uses.
Yes. There is no technique to learn — tilting makes sound immediately. The clear head lets them see what they are doing. Size and weight mean supervision helps.
Yes. It is quiet, so it needs a close mic. Position off-center where the beads travel, and expect to record it separately from louder instruments.
