"stacking". Stacking improves data quality because noise, which is usually a random addition to
the trace, tends to zero when averaged.
The following diagram displays how data is stacked. At each data collection point, the trace is
collected multiple times. Traces are averaged to calculate the resulting data trace, which is
saved.
Stacking improves data quality but may slow down survey production. The more stacks, the
longer it takes to collect data at each survey position. It is important to find the ideal number of
stacks that adequately detect the target.
Press Stacks to display the screen in Figure 6-7, where this value can be set. The current
number of stacks is displayed. Press the + and – buttons to change the value. With the Model
1600 receiver, stacks can be set from 1 to 2048 but most surveys see improved data quality in
the range of 4 to 64 times. With the Model 3200 receiver, stacks can be set up to 65536,
