3.1 Introduction
The Type 8300 (and variants) series Wideband
®
2 Transponders are designed for positioning, data
telemetry, data logging functions and remote monitoring of subsea instrumentation.
The Wideband
®
2 technology uses a correlation reception technique with phase encoded signals over
a wide range of carrier frequencies. Signal coding allows for hundreds of channels enabling multiple
users to work in the same area without interference.
The 8300 (and variants) series Wideband
®
2 transponders can be fully integrated with other
Sonardyne products from the 6G
®
range.

3.2 Compatt 6 Series (Type 8300)
The Compatt 6 transponder is designed specifically for full Long Baseline (LBL) subsea deployments.
The standard transducer housing is hard anodised aluminium but it is also available in aluminium
bronze and super duplex stainless steel as well as standard, mini, midi and maxi lengths, depending
on the operational requirements.
The Compatt 6 has a depth rating of 3,000 to 7,000 metres and is available as an omni-directional and
directional transducer. The transponders are available with different sensor options and release
mechanisms. The Compatt 6 is identified by a red coloured housing label.
3.2.1 Compatt 6
The Compatt 6 is approximately 1035 mm overall length (depending on transducer type and sensor
options) with a hard anodised pressure housing approximately 135 mm diameter, protected by a red
sleeve. The sensor endcap can contain a stainless steel release mechanism for releasing an anchor
weight. The Compatt 6 can be fitted with either a lithium or alkaline battery.
