A review from me, a person who actually owns one and been out testing it on volcanic soil, beach soil, highland mountain ovals and river beds.
The next thing to do is learn the target numbers, nobody wants a machine and learn only by digging hours of rubbish in the ground. So i took the F44 down to the beach, why a beach? well for a few reasons, one the sand is clean compared to the winter mud and second the sand has salt in it, a mineral which i want to know that the F44 can handle. Yes machine is good on salt without a issue.
The target id number list is on the video, but will repeat it here for you as well,
target id reads as follows
29 for a 5 cent coin
36 for a 10 cent coin
42 for a 20 cent coin
44 for a 50 cent coin
56 for a 1 dollar coin
52 for a 2 dollar coin
Next few days when the winter storms are gone i will do the target numbers for the older out of date Australian coins. How does she handle Aussie coins? very stable, hint being if you want a 20 cent coin, then make sure it is a steady 42, the beaver tab pull tabs that were popular in Australia in the 1970s and 80s comes up at 42 but that tab is a jumpy number 41 42 43 etc, it does not stay stable on the trashy pull tab.
Adjustable audio tones is the next point to explain, i have owned dozens of machines but this is the first one that has let me move the tone around on the machine. You put the machine in custom mode, hold custom mode for a few seconds and then you can move the high pitch sound to the 5 slot on the machine. The 5 slot is all target id from 50 to 59, is where the $1 $2 can be found and you want a high pitch, put the slot 4 to pitch level 2 and FE level turned down to 1. Then you set slot 6, 7 and 8 to either a high pitch or level 3, if hunting for $ coins leave all slots from 6 to 9 as a level 3 pitch.
Voltage Controlled Oscillator, VCO for short and it might take a month to explain VCO, it is the same as proportional audio used on Garrett machines, a small deep target has a weak short sound, a larger shallower target has a higher pitch, longer tone. This allows you to work out the depth of the target and the size by the audio. What sets the F44 and Fisher out from other brands using VCO is you can put VCO on one slot in the custom programmable tones, so if you hunting a threepence which depending on the silver content (they changed content once in 100 years) the number comes up around 60, so you set the 6 slot to VCO to find the small coin and the 5 slot to 4 (high pitch) to find the $ coins. Is just nice to be able to program the codes the way you want them.
Backlight is a must here in Southern Australia as winter nights kick in before dinner time, F44 back light has 5 settings from bright to just right.
