The main difference how a vibration plate feels has to do with the weight of the plate, length, and the tilt table which determines its amplitude.
The heavier gauge steel plates have a more push feel while the lighter plates have a more pop feel. Unless the machine has enough power, the larger heavier gauge plates usually don't have enough G Force at the pop of the acceleration and all you get is the G force delivered spread out over a longer time. The machines that give most people the best results have the highest G force delivered in the shortest time but only for a fraction of a second. This really depends on the type of tilt table the vibration platform is resting on.
Heavier people will want a different gauge of plate than a lighter person. Having a very heavy plate with a heavy person can offset the feel that a thin plate gives.
NOTE: I do not sell machines made of tin plates. Tin can vibrate and resonate unwanted vibrations which feel very incoherent when standing on these plates. I want the plate only to deliver the G force to my body. An 8 Gauge plate feels totally different than a light plate.
Depending on the goal you have, you may want a very lightweight plate. The Zaaz 20K and Hypervibe have one of the lightest weight plates out there and are super powerful. The Vmax Pulser is also very powerful but has a 27 inch plate and a heavier plate.
If using the vibration plate without shoes, the heavier plates do have less of a tickling feel. The shoes absorb a lot of the friction especially at high speeds. With a Hypervibe, I would always wear shoes on the high speeds.
With longer and heavier plates, more G force can be delivered at the lower speeds that makes up for lighter plates that have to go at a higher frequency to equal the same G force. Longer and heavier plates create more momentum instead of relying on a more powerful motor. The Vmax Pulser has a very heavy base to balance the momentum of the heavy plate. The Zaaz 20k has a shorter plate while its motor powers the plate with less momentum from the plate.
If trying to do lymphatic sessions, the shorter plates with a wider angle tilt table give a more pop feel which should drain more lymph per session than the heavier plates with the G force delivered more throughout the acceleration. Many of the plates weather they are light or heavy, long or short, they can still give some results but getting just the right plate for your weight and any kind of health issues or goals you might have can make the difference between a machine that does a so so job and a great job.
