1. Introduction

BLISSTOOL LTC48 is a contemporary professional metal detector, designed to be used on any 
type of terrains. It features perfect depth and discrimination and is outstanding for its high 

quality, easy user’s adjustment and minimal maintenance need. That makes it appropriate for 
both the experienced seekers and the beginners in the field.
It is equipped with a recharging 12V/2500mAh NiMH battery, ensuring up to 48 hours 
continuous work with a single charge. 
It mobility is complemented by light and robust detachable carrier construction made of 
duraluminum and carbon, light and robust ABS boxes, and 28cm (11") DD waterproof search 

coil.
BLISSTOOL LTC48 features an adjustable audio threshold, an adjustable discriminator and two 

working modes for eliminating the ground interference:

Manual Ground Balance, 

appropriate for terrains with a homogeneous soil. In this working 

mode, the metal detector could reach its full potential by a fine manual adjustment, made by 
the user;

Automatic Ground Balance,

 appropriate for terrains with heterogeneous soil. In this 

working mode, a special part of the metal detector’s electronics automatically eliminates the 

ground interference.
