SSND-SPEAR-A
Recommended for open bore options
The SSND-SPEAR-A is an intermediate silicone sounding rod engineered for controlled internal expansion and gradual urethral stretch. Featuring a long, smooth shaft topped with a soft, flexible spear head, this precision-molded sound transitions from a slim 4mm entry tip up to a 12.5mm maximum diameter across its 1" tapered lead section. Classified as an Intermediate urethral sound based on its 12.5mm (37 Fr) maximum diameter profile, it offers a ideal step-up option for users expanding beyond starter sizes.
Anatomical Sizing & Mechanics
-
Entry Tip: Begins at a slim 4mm (12 Fr) rounded lead tip to ensure low-friction entry into the meatus.
-
Shaft Progression: Tapers smoothly over a 1" head section from 4mm up to its 12.5mm (37 Fr) peak profile.
-
Main Shaft: Continuous, 11" sleek working length with no ridges, ribs, or valleys for an uninterrupted glide.
-
Safety Flange: Integrated base flange acts as a secure external stop to prevent over-insertion and provide an anchor point.
Anatomical Depth Guide Features a total insertable length of 12". The initial insertable section navigates through the penile urethra into the prostatic urethra and bladder region, requiring intermediate to advanced technique for careful placement along deep canal structures.

👑 Bob's Choice Recommendations:
-
Experience Level: Intermediate (12.5mm / 37 Fr peak diameter).
-
The Prime Durometer Recommendation: Recommend #10 (medium) silicone density as the primary choice for structural integrity, easier insertion without bowing, and high-definition tactile feedback.
Color Options: #18 and #30 are available in pure translucent. #00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.
