The bottom line It states the 2,5 mm socket, which is the two-character fact that decides whether your swinger will plug in — and it is the only listing here that does.
What the maker puts in writing
9 LEDs
T button volume · V button tone · S button sensitivity
2,5 mm plug, works with any fishing swinger
Red light band, rolls up and down
White LED power switch, pressed twice for anti-theft
Snap-on ear bar against rod slip · waterproof
The specification that makes the shelf work
2,5 mm.
This shelf sells alarms and it sells swingers. They connect through a jack plug, and if the sizes disagree nothing works. One listing out of seven states the size.
It is a two-character specification that costs nothing to print and decides whether two purchases go together.
The button names
T, V and S — volume, tone, sensitivity. Named individually, so you can find the right one without a manual and without light. Compare that with five listings here that say « adjustable » and leave you to discover which button is which.
Anti-theft
Ein weißer LED-Einschalter, der zweimal gedrückt werden kann, um die Diebstahlsicherungsfunktion zu aktivieren.

Questions that come in about this one
Why does the 2,5 mm socket matter?
Because that is how a swinger with a light plugs into an alarm. Seven items sit on this shelf and four of them involve a swinger; exactly one names the socket size. Without it, matching a swinger to an alarm is guesswork.
What does the anti-theft function do?
Pressing the white LED power switch twice arms it. The listing does not say what happens when it triggers — presumably it sounds — but it is the only security feature on this shelf, and on a public bank the rods are left alone for hours.
What is the ear bar for?
It snaps over the rod so it cannot slide off the alarm head. That is not about comfort: a rod pulled off its rest by a running fish goes into the water, and the listing names this as damage prevention.
Who this one is for
Pairing with a swinger you already own, and leaving the rods unattended on a busy bank
