Curve Fitting & Dive Table Creation
When gravity is the primary force acting on the probe, its depth can be predicted via a ballistic dive table.
The Dive Table is used to model the probe fall behavior during the deployment. Two tail spool options are
possible.
•
Tailspool with buoyancy module is used for deployments <100m to gain greater accuracy
•
Plain tailspool is used for deployments >100m
To switch between pre-defined dive tables:
1. Start the rapidCAST Interface software.
2. Click the Dive Table tab.
3. The CURRENT DEPTH-TO-TIME COEFFICIENTS IN USE table shows the currently used dive
table. To swap tables, select the Alternate Choice in the second table and click the Activate Se-
lected Row button.
The orange buoyancy tail spool module has a maximum depth rating of 100 meters. If you are
deploying deeper than 100 meters, switch to the plain tailspool.
If you have a new probe or are operating in an environment with varying water conditions, a
new dive table will need to be created. Please contact technical support for further assistance
with this.
