Delay accessories are stored in a MS Access database with
a default name of Stock.mdb. The database can be modified
with the MS Access software
The downhole delays dialog also allows the user to edit
some of the delay connector and primer properties assigned
to a particular design.
The downhole delay mode allows the user to insert
downhole delays one hole at a time, all holes at once, a
group of marked holes or a group of unmarked holes. These
options can be accessed via the downhole delay mode icon
selection in the tool bar.

Surface delays
Once holes are primed and downhole delays inserted, the
next step is to place surface ties between hole collars. The
placement of surface ties is carried out by activating the
surface delay mode function via the Mode+surface delay
menu item or alternatively by clicking on the surface delay
mode icon.
Before tying begins, the user must select the type of surface
delay element and the type of connection to be used. This is
done by accessing the surface delay dialog (Figure 2.16)
via the Parameters+surface delays menu item or
alternatively by clicking on the current mode parameter
icon.
Depending on position, surface delays are referred to as
inter-row ties or inter-hole ties, in addition the connection
of each surface delay can be specified to be bi-directional
or uni-directional (Figure 2.16).
