The S.701 SART from SevenStar Electronics Ltd is the result of many years experience in the specification, design, manufacture and use of SARTs and related marine safety equipment. It brings together the ultimate in high-reliability design and modern manufacturing techniques.

It produces an instantly recognisable .12 dot. radar return to alert & direct passing vessels and aircraft.

It is EU MED .Wheelmark. approved, and has been specifically designed with life-raft fitment in mind, as well as conventional carry-off use, is capable of auto activation in liferaft installations, and is the smallest SART available today.

Its exceptionally low power consumption makes it unique, in that it is the first SART that can use non-hazardous batteries . safer, cheaper and easier to ship, deploy and stock.

Its unique digital design brings new levels of sophistication, with guaranteed lifetime performance, reduced component count and increased reliability.

GMDSS rules state that all vessels above 300 gross tonnes must carry at least one SART, and those above 500 gross tonnes at least two SARTs.

SARTs have been proved to be invaluable in rapidly locating survivors - so much so that SOLAS requirements now specify SARTs to also be fitted to life rafts in Ro-Ro ferries.
