Setting a Redrill Tolerance in SHOTPlus™

A step-by-step guide to specifying Redrill Tolerance(s) in SHOTPlus™


A Redrill Tolerance is an amount of underdrill that, if exceeded, should result in a hole being marked as requiring redrill. Tolerances are defined per hole type, and holes may be checked against them after a Dip Length (also known as Actual Length) measurement is recorded.

For information on how the Redrill Tolerance setting may also be used by BlastIQ™ Mobile, see Loading rules for BlastIQ Mobile.


1. Navigate to Edit > Design Data


2. Set a Redrill Tolerance for each hole type


3. With the tolerance(s) set, any hole in the plan that exceeds the set amount of underdrill will automatically be marked as requiring redrill in the Hole Table
