2. Introduction
The rapidPro has been developed in two forms for the fast collection of sound velocity and CTD profiles.
Designed to optimally operate with the Teledyne rapidCAST underway profiling winch the rapid collection of
accurate sensor data is key. The Pro version of the rapid profiler is further developed with a new optimised shape
and removable ProLogger module that combines a rechargeable lithium ion battery, data logger, a GPS receiver
with Bluetooth comms.
2.1. rapidPro SVT
rapidPro SVT
The rapidPro SVT has been developed for the specific collection of sound velocity Profiles, at high fall rates
through the water column. Now further developed with a new optimised shape and removable ProLogger module
that combines a rechargeable lithium ion battery, data logger, GPS receiver and Bluetooth comms module.
ProLogger
The world’s most accurate Sound Velocity sensor with virtually instantaneous response time, high specification
thermistor temperature sensor, data acquisition rates of up to 32Hz housed in a low drag housing result in the
highest quality profiles at drop rates over 5 m/s.
Optionally, the rapidPro SVT is designed to operate with the Teledyne OceanScience rapidCAST underway
profiling winch to deliver the highest quality SVT casts. While the vessel is underway profiles up to 450m at 6
knots are expected.

2.2. rapidPro CTD and rapidPro CTDplus
rapidPro CTD
rapidPro CTDplus
The rapidPro CTD and the rapidPro CTDplus, with an optical sensor, has been developed for the collection of
conductivity, temperature and depth during fast drop rates through the water column. Now further developed
with an new optimised conductivity sensor shape and removable ProLogger module that combines a rechargeable
lithium ion battery, data logger, GPS receiver and Bluetooth comms.
ProLogger
Setup and data download is controlled with Valeport Connect software for PC.
As an option, the rapidPro CTD is designed to operate in conjunction with the Teledyne OceanScience rapidCAST
underway profiling winch to deliver the highest quality CTD and optional optical parameter casts. While the
vessel is underway profiles to 400m at 6 knots are expected.
