Detailed Description
(U.S. imports) to detect the depth of deep treasure-hunting instrument 8M,Total class and the battery life: 6 AA1.5-volt battery, continuous working time of about 20 hoursFeaturesAutotune automatically adjustAutomatic adjustment is an automatic adjustment of the beginning.When the time of operation of the device automatically adjust the sound signal can be maintained stable.Some early models only through the continuous press the button to control the appropriate intensity of the sound signal.The signal will sound or high or low, because the process of searching the earth mineralization reaction changes as the location is different.But if it is a great change in mineralization reaction, if needed to balance device regulation, small changes can be automatically adjusted.If the sound is not normal, then the instrument detection depth will be reduced.Ground reject the earth mineralization reactionTF900 a major feature is that it can rule out the earth mineralization reaction.When the probe to have the earth mineralization reaction, you will find the instrument how useful this feature.Because the earth in a capsule where mineralization reaction, TF900 can increase detection depth.Dual modes dual-modeTF900 In addition to All Metal mode, there is a TR / TRACE mode.TRACE model of the soil conditions are not in balance control and influence.This allows the instrument can detect underground space and caves.Different from earlier detectors, TF900 meaningless without some special operation.Those tedious and puzzling action often leads to incorrect operation of equipment.The instrument is adjusted in the production process before.When the selector transferred to TR / TRACE mode when the device can automatically work.TR/TRACE- fourth mode switch is specified by TRACE.Shimoji balance in this model does not work, the equipment will be affected by the earth mineralization reaction.Because there are no obvious holes or cave earth mineralization response to the sound equipment will rise.Under normal circumstances, the earth will cause changes in the density of the significant change in the sound equipment.If the sound decreases statement reflected in the increased mineralization.In this mode, the instrument can detect hidden in caves or other cavities in the metal.This role of the model need to be very careful planned search method, need to pay particular attention to the sound change significantly.Changes in the instrument where the sound for the next token can help determine the location of metal.
