Explore the depths of the next, move the electrodes on constant relationship (AB/2) 2 > 5 MN at any depth at all levels in this move the electrode spacing in Figure 55.
Exploring the depths Next. To move the electrodes to the constant relationship 2 (AB / 2)> 5 MN at all depths. In this survey, edged electrode According to the spacing in 55
The depth of the next. The move electrodes out according to constant relationship 2 (AB / 2) > 5 MN throughout all the depth in this survey electrode move according to the spacing in the form 55.
