Nomad Design DTX Sinking Minnow Saltwater Hard Bait - A self centering tow point ensures that no matter how many fish you catch, the lure will keep swimming straight. Conventional lures with a fixed tow point cannot all be made perfectly centred to swim straight. The ability of the Autotune system to perfectly centre itself every time on the bib means that the tow point can be pushed as far back on the bib as possible, meaning maximum diving depth and better action combined with higher troll speeds. Hydrospeed belly eyelet for maximum trolling speed. HD ABS System, an extra strong white plastic for overall strength and durability. Diamond Armour internal mesh system, internal strengthening design for transparent colours. (110, 125, 165, 200 & 220 models) Gorilla Through Wire, welded and supported for extra strength. (110, 125, 165 & 200 models) Metal Matrix Plate, stainless steel plate system. (220 models) Heavy duty BKK hooks and terminals.
