Onshore make up of 12 1/4″ Bit (Smith MDi813) to a Smith designed sleeve stabiliser specifically for Sperry’s GeoPilot tool. Sperry used to be very strict regarding the degree of spiral, or wrap on their sleeves and many decent bits/ sleeve stabs were needlessly rejected because of this.

Wonder if it did any good?

8 1/2″ SEC XS4 milltooth/junk bit.

Nail retention system for interchangeable nozzles an pin vent reservoir system clearly visible in the pictures along with tungsten carbide surf row inserts for enhanced gauge protection and a deep tungsten carbide shirt tail protection.

12 1/4″ SEC DBS ELC1, an IADC117W mill tooth bit, using Security’s ‘Energy Balanced’ concept where the cutting structure on each cone is modified and oriented in order to equalise the loads on each cone. Some argue this is a pointless goal to pursue as the loads on each cone will vary with parameters and rock type and cutting structure performance and efficiency is sacrificed in the pursuit of balance.

they look quite cool though.

This was also the subject of a large lawsuit between SEC-DBS and Smith in the last decade.
