Why C-3 D Circuit Continuity Indicator
Ultra-compact design
Fits in your shirt pocket. Weighs almost nothing and takes up zero space in your kit.
Why it matters: You actually carry it because it's not a hassle. A tester that stays in the truck doesn't test anything.
Bright LED indicator
Green LED lights up the moment you have continuity. Visible in direct sunlight or underground.
Why it matters: No squinting at a dim display mid-round. You get a clear go/no-go in one glance.
Secure contact testing
Spring-loaded contacts grip the wire firmly. No fumbling to hold a probe in place.
Why it matters: Frees up a hand and eliminates false readings from loose contact. Test faster, trust the result.
5-year battery life
Single battery lasts years of daily use. No recharging, no hunting for spares.
Why it matters: The tool is ready when you need it — not dead in your pocket because someone forgot to charge it.
Easy clip attachment
Belt clip keeps it on your person all shift. Grab it, test, clip it back.
Why it matters: Stays with the shot-firer instead of floating around the blast truck. Less time looking for gear.
Blasting-safe signal
Low-energy test current well below initiation thresholds. Safe around all standard detonators.
Why it matters: You confirm the circuit without adding risk to the bench. Compliance built into the tool.
Built for the bench.
Confirm before you fire
Quick visual continuity check on the entire shot circuit.
Safety-rated
Test current well below any detonator initiation threshold — safe to use on a live circuit.
