Merach CV30 Pro vs Merach CV40

Same 7 to 9.6 Hz band, same 2-year warranty, same 30-day home trial. The $50 buys size: the CV40's deck is 28.3 inches wide against 22.8, with 13 mm of travel instead of 11 mm and a 440 lb rating instead of 400. A wider deck lets you set your feet further apart, which is how you make a rocking plate work harder. The CV30 Pro is the lighter one to carry (17.6 lb against 23.1), and the only one of the two with a noise figure (65 dB or less, per Merach).

Both are oscillating plates: the deck rocks side to side like a seesaw. The difference is in the range. Merach CV30 Pro lists 7–9.6 Hz with 11 mm of amplitude; Merach CV40 lists 7–9.6 Hz with 13 mm of amplitude. A wider frequency range gives you gentle settings and stronger ones on the same machine.

On November 12, 2026, Merach CV30 Pro was $119.99 and Merach CV40 $169.99, each on its brand's own store. That is $50 between them. Neither needs consumables or a subscription. Warranty: Merach CV30 Pro, 2-year warranty; Merach CV40, 2-year warranty.
