Extra Lengths - Electro ConstrictionAdditional lower lengths are available to help in finding the perfect fit, or for use with multiple players. Additional lower stages complete with liner. Sizing: Internal diameter (40mm or 50mm): The size refers to the internal diameter of the lower section. 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

The V2000/Tremblr connection hose also has a small automatic air expulsion valve - this helps to keep the SPT receiver in position

Adjustable ‘telescopic’ length to optimise sensation

The three electrodes allow a choice of contact – or tri-phase stimulation

Having an adjustable height glans cup or sound and an adjustable height ring electrode allows accurate positioning for optimal sensation

So measure the erect penis length to the groove around the base of the glans

Unfortunately

The fluid itself is the electrode – there are no physical contacts in the upper section

The ring electrodes have the same diameter as the lower stage

When using the SPT it is possible to adjust the length of the penis by varying the vacuum strength and also by adjusting the balance between constant and pulsating suction
