Twin Cage

Fitted with polished aluminium tube electrode at the base and a twin conductive rubber ‘glans cage’ for the tip. Adjustable ‘telescopic’ length to optimise sensation. The SPT is bi-polar which means it can be used on its own and does not require another electrode to complete the circuit.

Sizes 40mm or 50mm diameter. Scroll down for sizing information.

An adaptor kit is required (+18) for use with the original Surge Milker.

Sizing:

This SPT has an adjustable telescopic length to position the electrode just where you need it. Simply choose an internal diameter.

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).

An adaptor kit is also required (+£18) for use with the original Surge Milker. This can be ordered HERE.

BI-polar E-stim:

The SPT is bi-polar and can therefore be used on its own. If you are new to Electro-Stimulation you can learn more on our FAQ page.
