### ⭐⭐⭐⭐ Efectividad
*by J***E on April 20, 2021*

Empece comprando otros tipos de detectores, luego que encontre este inficon tekmate ya llevo mas de 15 años comprandolo. El unico defecto es la carcasa que es muy debil y tiende a quebrarse con el tiempo pero el beneficio de un buen detector me hace pasar por alto dicho defecto.
