An adaptor kit is required (+18) for use with the original Surge Milker.
This SPT has an adjustable telescopic length to position the electrodes just where you need them. Simply choose an internal diameter. O-rings on the lower section are removed or added to adjust the length.
Internal Diameter (30mm, 40mm, or 50mm): The size refers to the internal diameter of the SPT. 40mm is by far the standard size. Due to the way the milker works the sizes are not that critical - as long as the penis will fit inside the acrylic tube when erect. Diameter is calculated by dividing the circumference by 3.142 (π).
The Three Ring SPT has three separate connection options allowing for a choice between bi-polar and tri-phase E-stim.
An adaptor kit is also required (+£18) for use with the original Surge Milker.
