This is the Triple Horizontal Egg. Each of the 3 sections is balanced, the conductive area is similar across all 3 zones, at about 2100 mm². The size at ~ 40x60mm is large, but not overwhelming, and fits very nicely. It turns out the egg shape works extremely well with the prostate, and is very easy to insert and remove.
One use example - this is a wonderful, easy setup that hits the prostate hard, and requires only 2 parts. You will need a R3B and this head.
Wiring: ChA: Corona side (bigger) of the R3B, and the base of this head (base is the one without green circles).
ChB: Frenulum side of the R3B, and tip of this head (the tip is marked with those small triangles).
This setup is intense, and incredibly nice — hitting the prostate very deep, lighting up the perineal nerves, and is just amazing.
There are tons of variations of this. If you have never tried tip-to-probe stim, order this head.
Note: like all 25 series multiconductor heads, the clearance for cables is small — the max diameter of the 4mm banana plug is 8mm. The PlaStim cables are this size; instructions to make them are here: DIY Cable. They are also available in the store — you need the vertical versions of the cable.
