Read the Full Story & Testing Notes

Lollipop shaped, and one of the two heads that ships on a probe. It is not my primary head, but it is good - and it is a genuinely different feel from the Cylinder.

Because of how the contact area is laid out, the Sphere is a little sharper in sensation and you feel it a bit more. It moves well with muscle contractions.

Pick your series and head size above. Heads are series-locked: you get the head built for that shaft diameter, and it fits that series only. A 25 Series head will not go on a 32 Series shaft.

Sphere or Cylinder?

Honestly, they are very similar, and both are good. The difference comes from the contact area layout:

Sphere - lollipop shaped, a little sharper, you feel it a bit more.
Cylinder - larger flat area, so it hits more evenly.

Both move well with contractions. Sometimes you just want to mix it up - and at $17 you can, instead of a couple of hundred dollars for another big-brand probe. That is the whole point of a modular system.

How to run it

Single conductor, so the whole head is one pole and the other end of the channel goes somewhere else on you. You want the current flowing through the prostate, not just near it - so the one to start with is a channel from the head out to a ring, like the Pinnacle or The One. Head to the probe base works and gives the contraction feel, but keeps the current up top. Head to perineum pad is another good one.

Cables

Clearance in the head is tight: the cable head has to be 8mm or under. If you already have 4mm cables, measure them first. Being a single conductor, one cable does it - a 90/straight is ideal, straight end into the head, 90 on the ring. 2.5mm ends if you are on a Coyote, 3.5mm for most other boxes.

Details

M2×40 screw hole at the port - the screw cuts resistance about 30% and strengthens the neck. Locks into its shaft with a 90° PlaLok™ turn - check the lock indicator before use.

Care: consumable part - inspect before every use, disassemble to clean with warm water and dish soap, and follow the Care and Safety Instructions.
