the idea to make frequancy meter with other controller (avr-pic) with lcd also with programming (gold - silver - iron .. etc) :| . i will post soon the full pic for that

thank u mr mbasko for your help . i think the main point there pulse defrent . .... the resestance .& inductance in minilab search coil resestance les les tham 0.5 ohm and in tdi sl 1.6 to 2 ohm in minilab we can say rx cap middle (145 -150)pf in white tdi sl (????????????)pf in minilab...

This the imformation about minilab serch coils . now we need some one give us whites tdi sl serch coils information DD Coil Measurements. Minelab 11"DD GPX coil. Coiltek 430 x 280 DD Pro. SEF 21" x 17" DD. TX pins 5-4 Inductance = 294 uh. 249 uh. 293 uh. " " " Resistance = 0.4 ohms. 0.5...

dear in my area i can t get coiltec tdi or other s search coil which working fine so i wont to try to using them in my tdi spp but with little change in hard ware to make the search coil harmonic with my tdi spp. i have 12 inch tdi coil . but i want to make larger coil for more depth in gold...

I am about to finished about the LCD .. I studied the controller pin out diagram for 16f And I will send you later the video for that,, Yes we can add LCD for spp Rgds

My first folded coil Resistant 1.8 ohm 300uh 5v8 coil I win to detect 0,3 gram gold Later I am going to make the new design as with two separate folded coil in one rx tx file As to give same DoD shape . And what I understood that the delay 10sc need you make the search coil not more...

this from mr reg who itink desgner folded mono :_ The dual field design coil was primarily developed to provide decent depth on large objects plus enhanced sensitivity to small gold. The design which was patented by the late Dan Geyer while he worked for Whites and works very well for this...

last i find the sulusion my idea to build folder mono coil 5>9 like reg search coil may this solve this issues rgds

this from memeber (reg) There has been some confusion about using DD coil on The TDI series of detectors. In fact, someone from OZ mentioned to Miner John that Eric Foster indicated that DD coils wouldn't work on the TDI units. To the best of my knowledge, Eric never said that. What he might...

Plz look to this design all this down pic we xan do it as mono coils If we can do good things ,, plz any update for helping , I need your Feed back . Rgds

Dear If Dd coil working in tdi or spp that means rx and tx in pcb board are accept working with DoD search cable. That for DoD cable has two Rx cable same as one . I am going to make DoD search cable same as 2 point 1- same one tx and rx mono spider cable in same time. 2-or same as dd...

so by this information up beside your more information we hop to succes to do some things rgds

pcs spp white if look in down board you find jumper . now its workin no 3 and 4 together .

Simple thing to try first would be (as already suggested) try a small coil like a Nugget Finder Sadie 8"6" mono, Coiltek 6" coil etc. Here's a thread on several small coils being tested on the Whites TDI Oz Pro : https://www.prospectingaustralia.com p?id=21209 The Nugget Finder Sadie is a...
