This Treadwall has the smallest footprint that we manufacture. But the climbing surface is exactly the same as the M4 Pro. If you've got a very crowded gym floor and the overhanging or inclined angles are not going to be as utilized by your customers the M4V might be the perfect unit for you. By changing the difficulty of the hold settings you can still tailor the intensity of the workout to your clients.
