Spec Sheet (PDF 1.7M)

The ESI/2 is the next generation of our electronic shock tube initiator. It uses our patented tip to provide reliable initiation of standard commercial and Mil-Spec shock tube for 10,000 shots.

Two-button operation and an under-voltage lockout assures that the unit will not fire prematurely and safely discharges in the event of an aborted shot.

Each unit has a tough rubber boot to accomodate rugged environments.

Spec Sheet (PDF 772k)

The D80/ESI is a hand-held combination electric and shock tube initiator.

The shock tube adapter contains four separate maintenance free electrode assemblies giving you three spares when the first one wears out.  Each electrode delivers 1,000 shots.

The electrodes are true zero-maintenance assemblies.   No re-carbonizing required.   No re-carbonizing with a #2 pencil required.

Adapters will fit standard commercial shock tube as well as thick-walled and Mil-Spec shock tube.   The unit comes with one fitting for each size, but can be ordered with two fittings of either size.

The D80/ESI can drive an electric breech on the PAN disruptor cannon. This PDF file contains specifications for this capability.

STSS - Shock Tube Saver System
Photo of STSS
(Click for full size image)
The Shock Tube Saver System is a kit consisting of a power pack, a single-channel shock tube initiator, and 500 feet of lead line on a spool.

The system is designed to allow the user to reduce shock tube consumption by at least 95%.

Instead of running 500 feet of shock tube downrange, you can run 25 to 50 feet of shock tube from the shot to the rugged initiator. You then use 500 feet of lead line to run from the initiator back up range. The power pack is used to power the initiator through the lead line from a safe distance.

The initiator and lead line can be recovered for reuse resulting in the use of only 25 feet of shock tube instead of the 500 feet. In this manner, the system pays for itself within 25 shots.

In addition to the cost savings, this also means that you have less shock tube that needs to be transported to a remote site, less to haul back out, and less to account for, allowing the user to fire more shots per reel of shock tube.

Over $400,000 can be saved in shock tube cost alone over the 10,000-shot life span of the system. Full details can be found in our Cost Analysis and Return On Investment.

As with all of our other commercial products, this system is covered by our No-Nonsense Guarantee. If it breaks, send us the pieces and we'll repair or replace it at no cost.
