Thanks I need to create coil for 350 at 450uh for delta pulse or sniffer xr71 do you have recommandation for the type of wire needed?50 stranded wire 0.07 plated wire are good choice?please
Ask Dave as he has the measurements, I have not made any coils for years and do not know exactly off the top of my head. Contact him via detectormods.com
In just about every coil it should be made from litz wire , even the cable from the coil to the detector should be coaxial litz wire with spiral braid.
woody ..waht mean the Q of coil ..thanks ..and i hve avr lcmeter i use for coil metal detectors .when i testing induction of coil showing ohms .how much induction and (Q) i dont know waht mean the (Q)...thanks alot
Try test it out tarnagulla way, Seems to be drying up and mozzies aren't too bad It's where i use my modded 4500, Can run front gain on about 70% and rx gain on 8 with no ground noise Try do 8 rx gain on a normal 4500 and it's no where near as good! Can't wait for 2nd lot of mods I live out tarnagulla, So gunna be making a test patch shortly for the public to use. Happy for you to borrow the 45 for a day if you need to compare standard/variable frequency modded + front rx gain mod/New chip mods/ first and 2nd gen mods combo Would love to see all 4 against each other! Can 100% vouch for your mods, Fantastic work woody.
Hi I am writing to you from Bulgaria You could modify my 4500 to work well in clay and wet soils with large mono antennas 25-40 inches For searching for antique gold silver and bronze objects Thank you
