Those extreme depth ranges on medium sized and bigger metal objects make frame mounted search coils unnecessary in some cases. Small items can be eliminated by increasing the distance between the coil and the ground. This 45 cm coil covers much more ground than a 26cm coil does and therefore makes very effective searching possible. Coins with a diameter of less than 15mm should rather be detected with smaller search coils.
