1. Introduction

BLISSTOOL LTC42 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/2.5Ah NiMH battery, ensuring up to 48 hours continuous 
work with a single charge. Both the solid light aluminum detachable carrier construction and 

the watertight 28-cm Double D search coil add to the device’s mobility.
BLISSTOOL LTC42 features an adjustable audio threshold, automatic ground balance and 

improved discrimination that ensures:

Adjustable NOTCH Filter

, used to determine the detection/rejection level of contemporary 

non-ferrous pollutants (aluminum, bottle/jar covers, foil, silver-paper); 

Adjustable Discriminator

, used to determine the detection/rejection level of ferrous metals 

(iron objects, heavily corroded iron).
