Name: Delkim Ev-D Bite Alarm
Brand: Delkim

The Ev-D is Delkim's entry-level digital alarm and the replacement for the discontinued Ev Plus. It uses the same vibration sensing and signal processing as the flagship Txi-D, in a smaller body, but it is a non-radio alarm: it does not transmit to a receiver.

Who it suits

Anglers who fish within earshot of their rods, want Delkim's vibration sensing at the lowest price, and don't need a receiver. If you might want a receiver later, the Txi-D v2 is the upgrade path, because the Ev-D cannot be made wireless.

Worth knowing

The socket on the alarm is for illuminated hangers, not a transmitter.
For a budget alarm with a receiver, look at the Fox Mini Micron X or Sonik Herox.
