Who it suits

Anglers who want a small, light alarm with a receiver and Nash's build quality without paying for the R4's sensing modes.

Worth knowing

  • The plain Siren S5 runs on a CR2 3V battery and has no transmitter; make sure you're buying the S5R if you want a receiver.
  • Step up to the Siren R4 for wave and speed sensing and a rechargeable receiver.
