The NONEL® Shot Pattern Guide is designed to assist the blaster with surface timing sequences. It is not designed to illustrate
the connection of surface delay units to downhole units but rather is intended to offer surface timing sequence suggestions. Proper
training, the correct use of NONEL® products and using the most appropriate shotpattern for the application greatly reduces the
NOTES
probability of shot failures. Common shot failure causes include shovel cuts or nicks during stemming, shrapnel from surface
detonators, kinks or knots in shock tubing, cuts or nicks caused by stepping on or driving over shock tubing and improper shock
tube connection in connection clips.

These diagrams illustrate the "best practices" forconnection of surface delay units with down-the-hole units and other surface delay units in the blast. They are intended to
help the blaster eliminate potential misinterpretations of the diagrams on the following pages. Timing patterns and proper hook-up procedures are two separate things. The
enclosed timing sequence patterns are suggestions only. Not all information and/or field situations can beillustrated to cover every application or variation of conditions under
which the products are used or a blaster may experience.
