Pick the HB-10 when you are firing small construction shots and want a compact, hand-held electric initiator. 50-ohm capacity, 9V battery, fits on your belt. Roughly 20 caps per single series.
Pick the HB-55 for mid-sized electric shots that need built-in circuit continuity verification. 135 ohm capacity, fires roughly 62 caps in single series.
Pick the S-355 when you need 230-ohm capacity in a compact form factor. Continuity indicator built in, rapid charge, fires roughly 110 caps per single series.
Pick the HB-SBS when crews switch between electric and shock-tube circuits. Auto-detects what is connected. 250-ohm electric capacity, fires roughly 120 caps single series.
Pick the HB-320 for large production circuits and harsh environments. 220-ohm capacity, 19-joule output, AA-battery powered, CE approved. Roughly 105 caps single series.
Pick the S-412 for large electric shots where pre-fire continuity verification is critical. 240-ohm capacity, continuity indicator, fires roughly 115 caps single series.
Pick the HBR-20P for underground coal and gassy metal/non-metal mines. MSHA-approved permissible unit, auto-shunts output 4.5–8 ms after firing. AA battery, roughly 20 caps single series.
Pick the S-2 for shock-tube firing on large surface benches. Two 400-volt outputs, 12 joules each. Immune to stray current and RF energy.
Pick the S-3 when you need a high-energy dual-initiation machine. 12-joule output, 240-ohm capacity, continuity indicator. Fires roughly 115 caps single series.
Pick the S-27 as a robust non-electric shock-tube firing device. 400-volt, 12-joule output. Heavy-duty build for production benches.
Pick the HR-3 when you want a battery-free mechanical starter for shock-tube initiation. No electronics, no batteries, no charging — a reliable backup for any non-electric circuit.
