1. Introduction BLISSTOOL LTC48X is a modern professional metal detector, designed to be used on any type of terrains, including highly mineralized terrains, terrains with a high content of ore and highly contaminated terrains. Has perfect depth and discrimination and is outstanding for its high quality, easy user’s adjustment and minimal maintenance need. This makes it equally suitable for beginners and experienced searchers.
2. Features – Technology: Induction balance (VLF) – Working frequency: 8.
3. Versions BLISSTOOL LTC48X is available in two versions: version 1 (LTC48X v1) и version 2 (LTC48X v2). On the front panel of the metal detector both versions are labeled LTC48X, but on the box with the electronics, additionally marked is the exact version of the metal detector. LTC48X v1 is the standard version, LTC48X v2 is a version specially adapted for heavy field conditions.
4. Modifications Both versions of BLISSTOOL LTC48X are offered with 4 different options for power (capacity and type of the battery, battery charger): 1/ Rechargeable battery NiMH 12V, 2500mAh (10х1.2V, GP NiMH) and automatic battery charger 12V, 250mA (Working with a single charge: up to 50 working hours; Long battery life: approximately 500 cycles of charge-discharge; Battery weight: 330 grams.); 2/ Rechargeable battery NiMH 12V, 2200mAh, Low Self Discharge (10х1.
6. Optional accessories 6.1. Army backpacks (Kitbag) The army backpacks is soft backpack type bag in which can transport metal detector BLISSTOOL LTC48X. The army backpacks carried as a rucksack on your back. BLISSTOOL LTC48X be placed in the army backpacks after disassembling. For this purpose, its detachable carrier construction is divided into its three major parts through the unscrewed of the small and large fixing ring.
7. Device construction BLISSTOOL LTC48X consists of the following basic elements: 1. Carrier rod 2. Large fixing ring 3. Electronic block with control and indication appliances 4. Handle 5. Armrest 6. Power supply module 7. Intermediate connecting rod 8. Small fixing ring 9. Lower connecting rod 10. Plastic bolt and nut 11. Search coil Fig.
The carrier rod is made from duraluminum pipe. The large fixing ring that is mounted on its lower end is used for connecting the pipe with the intermediate connecting rod. The electronic block consists of a plastic box in which is mounted the metal detector’s electronics. The control and indication appliances lie on the front panel, the back panel and the bottom of the box. The handle is part of the carrier rod and is coated with soft and solid foam.
8. Device assembling and disassembling The metal detector BLISSTOOL LTC48X is assembled in the following sequence: 1. The upper part of the lower connecting rod is attached to the lower part of intermediate connecting rod via the small fixing ring, and adjusted at the appropriate length.
9. Control, adjustment and indication appliances The control, adjustment and indication appliances lie on the front panel, back panel and bottom of the electronic block (Fig.3). Description of the various appliances: 9.1. VOLUME potentiometer The VOLUME potentiometer serves as the on/off the metal detector (level "OFF POWER") and to regulate the audio volume (levels from "1" to "MAX").
To determine which of the three zones eliminates the best influence of soil is necessary: - choose the auto ground balance working mode (GROUND switch turned to "AUTO" position); - turn the DISCR LEVEL potentiometer to "GBS" position (Ground Balance Setting); - turn THRESHOLD potentiometer to a level, just before the level where the metal detector starts slightly zoom sound made (issued torn sound, buzzing, whiz) or one or two levels before the level of zoom (recommended for beginners searchers).
The balancing is actually finding the level (position) from the GROUND potentiometer, in which the descriptions in the way of movement of the metal detector search coil does not beeps or issue possible weak sound, or at least to preset audio threshold level did not change significantly.
9.6. DISCR LEVEL potentiometer The DISCR LEVEL serves for adjusting the detection/rejection level of iron, tin-foil and low-grade non-ferrous metals (usually pollutants), and for baseline exclusion of the discrimination (All metals mode) when it is set to level "0". In level "0" the discrimination is excluded, ie the metal detector makes unaltered sound for all metals, ie it does not distinguish them.
In light and clean terrains is advisable to work at level "NORM". In polluted terrains, terrains with hot rocks and mineralized terrains is desirable to operate at levels between: - For LTC48X v2: from „NORM“ to „4“. - For LTC48X v1: from „NORM“ to „6“. Higher levels should be set only in extreme necessity.
- If the detected signal is from ferrous metal (iron), then with increasing the levels of DISCR DEPTH potentiometer from level "0" to about level "10", at high levels will lead to the emergence of the typical for ferrous metals double pulled sound and/or to the level of total rejection, or at least pop of the signal. Actual level at which rejection begins (the pop) is in direct proportion dependence on the depth of which is buried the ferrous metal.

10. Device adjustment and preparation for work The metal detector is ready for use when the battery is charged and intact (the BAT LOW LED is not lit up). Before initial use, to the modifications with NiMH battery, please charge the battery at least 8 hours (from 8 to 16 hours) through the automatic battery charger available in the standard package, as described in 12. The NiMH battery reaches full capacity and respectively toughness, after at least about 5 cycles of charge-discharge.
The search consists of a uniform and slow swinging of the coil one side to another, while the user holds the metal detector’s handle and uses the armrest for support. Too fast or too slow moving of the coil could result in shortening the search depth, especially for deeply buried or small objects. The search coil path during the search resembles a zigzag movement, which is a result from the uniform and slow swinging of the coil one side to another while the user is moving forward.
12. Battery. Battery charging BLISSTOOL LTC48X is available in several modifications according to type, capacity and configuration of the battery. Please before you continue with this point read detailed the information available in 4. The battery is located in the power supply module and is connected to a metal detector electronics via a standard 6F22 battery connector, which creates an opportunity, if necessary, easily be on, off, replaced.
13. Practical recommendations The metal detector BLISSTOOL LTC48X is designed to find metal objects buried in the ground. It does not work well in residential areas and rich urban environment because it is highly sensitive electronic device and is troubled by surrounding electric devices, systems with electricity and metal objects (metal parts of the structure of the property, equipment and furnishings of the property).
appropriate technical support. 14. Indicative and recommended settings 14.1. Introduction. BSMD code Available below indicative and recommended settings are set from the indicative and recommended levels for adjustment of the individual adjustment appliances of metal detector BLISSTOOL LTC48X (potentiometers and switches). They aim should be to help the beginner searchers. Furthermore, they can serve as a base at learning how to set the metal detector BLISSTOOL LTC48X.
