Ellon-based Impact Subsea has released the lite version of its recently launched ISA500, a 500kHz underwater altimeter which provides heading, pitch and roll.

The new ISA500-L provides solutions for underwater altitude and distance measurement applications.

The unit, which can be upgraded to a full ISA500 with heading, pitch and roll features, is provided with an in-field firmware update feature to add new output strings and capability.

Alastair Mclennan-Murray, Technical Director of Impact Subsea, commented: “The ISA500-L is based on the ISA500 hardware, which has been designed from the ground up to lead the market in terms of altitude measurement technology. The unit achieves exceptional stability and range capability while at the same time being very flexible.”
