41. Airburst fuzes have to have the fuze length ( running time ) set on them. 42. The fuzes on influence mines allow many different permutations, which complicates the clearance process. 43. Bomb fuzes incorporating anti-handling devices were specifically designed to kill bomb disposal personnel. 44. By 1944 a large proportion of the American electronics industry concentrated on making the fuzes . 45. All versions have impact and proximity fuzes . 46. Four of the fuzes were conventional horns in the buoyant upper hemisphere of the mine. 47. However, since magnetic fuzes are electronic, their operational life relies on battery power. 48. Later fuzes were sensitive to pressure or pull and could be used with a tripwire. 49. British time fuzes , required for airburst shooting, were powder burning ( igniferous ). 50. It is compatible with the fuzes used with the TM-62 series of mines.
