My air test depth and in ground actuall depth is like night and day! I'll say one thing, the Kruzer loves nickels.
Carolina would you say in ground depth is deeper ? I've just been testing with different gold rings set at different orientations in air to see how the detector performs. I really need to get to a beach and see how it does in saltwater down here in the Gulf of Mexico. Watching the pre release videos in wet sand and in saltwater the detector appeared to perform really well. I just hope I can get the same real world results that we witnessed in the videos.
kajunman: My experience so far is air test are twice the distance as in ground test or more. My first experience in saltwater and damp sand I used the number of scoops required to retrieve a target as a judgement of depth. This seems to be inaccurate. Possibly pin point issues required more scoops and target in sidewalk may have slid to the bottom of hole?
My second test was actual coins buried and scanned in damp sand. Also in two feet of water I placed coins on the bottom and raised the coil to see depth in beach mode. to say a US clad coin would give a audible signal at 6" is a stretch. In damp sand 8". My settings were as follows in 19 kHz. Beach mode, GB 00, disc. 00, notch 15, T break 16, iron off, volume 3, gain on damp sand 75 to 77. gain in water at two feet 80. At a depth of 3' gain could be raised to 99 if sweep speed was kept around 3' per second.
I will be interested to hear your report from the gulf.
