Smart battery tester to check your batteries.

If an EVOtagger doesn't appear in the list of taggers when you pull the trigger and you can't remember the battery status from the last time you used it, this battery tester is really handy.

Remove the 9V battery from the EVOtagger and read how high the voltage is. If the voltage is below 6V, the battery must be changed, as the bluetooth connection becomes unstable.

In addition to 9V batteries, it can also test:
Micro (AAA)
Mignon (AA)
Baby (C)
Mono (D)
Lady (N)

Dimensions: 77.5 x 34 x 14.3 mm

Note: This tester uses 1xAAA battery, which is not included in the package.
