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.

Fig.1 / Metal detector BLISSTOOL LTC48 – construction For easy assembling and disassembling of the device, in the standard pack: – the carrier rod, the fixing ring, the electronic control module, the handle, the armrest and the power supply module are combined in a single component; – the small fixing ring is mounted on the intermediate connecting rod; – the lower connecting rod and the search coil are assembled together with the plastic bolt and nut. Fig.
The intermediate connecting rod is made from duraluminum. At its upper end it is connected by the large fixing ring to the carrier rod – it fits into it, while at its lower end it is connected to the lower connecting rod. The lower connecting rod is made from carbon, so that it does not interfere with the normal working mode of the metal detector.
. Device assembling and disassembling The metal detector BLISSTOOL LTC48 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.
. Control, adjustment and indication appliances The control, adjustment and indication appliances lie on the front (Fig.3) and the back panel of the electronic control module. Description of the particular appliances: 1. VOLUME/POWER knob: - It serves for both switching on/switching off the metal detector and adjusting the audio volume control. The chosen position from the knob scale (usually between the 3rd and the 5th level) should correspond to pleasant sounds made by the metal detector, i.e.
balancing process of the device according to the above description. The balancing should be carried at an area with no metal objects near the search coil (otherwise they would interfere the balancing process). This is easily established, if the GROUND knob is turned to a middle position and the search coil is moved horizontally above the terrain, i.e. without changing its distance towards the ground. When there are no metal objects, the predefined from the THRESHOLD knob sound would not be changed.
6. Loudspeaker: - It serves for producing a sound when an object is detected. The sound is deep-toned and non-pausing for non-ferrous metals and recurring (repeating) for ferrous metals (iron). The loudspeaker lies on the back panel of the electronic control module. 7. PHONES jack: - If necessary, the stereo headphones with 3.5mm jack could be plugged in the PHONES jack.
9. Device adjustment and preparation for work The metal detector is ready for use when the battery is charged (the BAT LOW indicator is not lit up). Before the initial usage, please charge the battery for minimum of 8 hours, by using the automatic battery charger available in the standard pack, according to the description in 11. The built-in battery ensures up to 48 working hours without recharging.
10. Search method The metal detector searches while being moved, i.e. it reacts to a metal object buried in the ground only when the search coil is swung above it. Searching for metal objects is actually moving the search coil above the ground surface. While doing this, the search coil has to be held parallel towards the ground surface and at a minimum distance above it. The more lifted the coil, the less deeply the search.
11. Battery charging The metal detector BLISSTOOL LTC48 has 12V/2500mAh NiMH battery that is placed inside the power supply module. The battery has around 500 charging/discharging cycles (battery “life”), after which its capacitance drops sharply and must be replaced with a new battery. The battery charging has to be done only by the automatic battery charger BLISSTOOL DA12250 (~220/12V, 250mA) that is included in the standard pack.
12. Practical recommendations One of the most important components of the metal detector is the search coil, which to a great extend determines the device’s sensitivity. When the metal detector is carried, for example in a rucksack or a travelling bag, an exceptional care should be taken to avoid the bending of the coil cable near the muff at the base of the search coil. That may result in tearing the cable connecting cores and damaging of the search coil and the metal detector.
13. Technical maintenance and service support during warranty The metal detector BLISSTOOL LTC48 has a 3 Year Worldwide Warranty for the quality of the produced components and in case of any factory flaws.
