The material sets of group 3 are divided into two parts. Part 1 comprises material
sets 12 and 13. Part 2 comprises material sets 14, 15, 16 and 17. In part 1, all the
depths of detonation are detectable certainly between points 1 and 22. For both
material set deflections, the point 1 and point 4 deflections increase for each
detonation depth up to 11.354 m and then decrease until the depth of 18.354 m is
attained. Points 8 and 12 similarly increase but only up to a depth of 10.354 m,
