Untagged detonator

found

Test All

When the Ranger detects a detonator that still has the internally

recorded factory ID, which means that it has not been

successfully tagged, it will trigger the untagged warning.

The Tagger may be used to find the untagged detonator on a

string using the binary search technique.

Once the untagged detonator has been found, it must be tagged

with a delay or location (or both) as per the blast plan.
