[QUOTE="user 12139, post: 573685, member: 12139"] mbasko, I understood Reg's point, but it does leave the door open for debate. Regardless of coil brand, most PI coils are built around ~300uH. A coil is nothing more than a tank circuit, you will find the parasitic parameters near consistent across all PI coil brands when you've ~300uH. Add the coil cable and you now have a completely different ball game, get the coil cable combo right and your good to go... and I'm not talking about wiring configuration either, [b]so be warned![/b] If your coil & cable combination is out of tune for the PI, then you'll blow smoke. MPS, DVT or whatever really has nothing to do with the coil, they are time domain; transmit cycles & receive algorithms (number crunchers). Give me any ~300uH coil (PI or VLF... whatever) that has no dampening or chip and I'll make it work on a GPX without blowing smoke. It may not be the best coil but it will work [/QUOTE]
