How we calculate scores →About this gear
A straightforward, manually activated personal locator beacon. The ResQLink 400 has built-in buoyancy, GPS/Galileo positioning and visible/infrared strobes, without the display found on the View.
Consider before buying
It sends emergency satellite alerts and a homing signal, but offers neither normal messaging nor an AIS alert to nearby boats. Battery replacement is due after five years or emergency use.
Our take
Choose the 400 if you want the simpler display-free option. The View makes status information easier to read, while the 410 RLS adds receipt confirmation. For a diver, carrying arrangements and suitable depth protection deserve as much attention as the beacon itself.
