Whites TDI Pro And Detech Coil

I just ordered and detech 11 ultra sensing spiral mono. I’m going to test it out on the old big box TDI. I was going to use it for some gold but try it out in the deep relic fields too. I’m hoping it will do well on sub gram nugs. I dug some pretty small lead with it when relic hunting. I found quite a bit of tiny pieces of camp lead and small buckshots at a descent depth. Many a better coil will make this coil more effective. Also 

**Make this machine  more effective. I’m going to use it on a GPX 4000 as well.

I also have just bought a TDI Pro that came with the stocK 12'' DF and 7.5'' DF coils,but i wont be using them as i am looking for extra depth in relationship to hoard hunting for any decent artifact but especially for one site that i have permission on it has produced 20 Celtic gold staters in a very tight radius,this indicates the chances of finding a hoard rather than say a purse drop.

Also have bought 3 new additional coils these being the Coiltek 14''x9'' Goldstalker Mono,15''x12'' Commander Mono,and a Detech 18'' Mono,i wont be looking for small gold nuggets as i am based in the UK and we dont have gold fields but we do have some stunning gold artifacts and coins going back possibly 1000s of years.

The Coiltek 14x9 coil will be replacing the DF coil as the stock coil as its not only lighter but i am finding it sharper on targets and a little deeper,infact its a very nice combination to swing for a all day detecting session,if i am then looking to go slightly deeper in my quest for artifacts or hoards,then the Commander coil will be the weapon of choice,it will be deeper and still be reasonably light,although i would think it would need a harness if used for greater time durations,but initial testing it is looking like a good detector/coil combination.

Then we get onto the BIG fella the Detech 18'' coil,must admit when i bought it from a closing down sale i took into account the cost/usage/reward ratio into account,the reason being these coils can sit idle in a corder gathering dust for a long period of time as its not your everyday use coil,but the cheap closing down price ticked my purchasing decision,was expecting it to be a real heavy bruiser of a coil,but when it arrived i was amazed how light it was,but as it is a Mono then i guess you dont require double the amount of heavy wire as in a DD coil.

Over time and as i get use to using the TDI Pro i will giv e some honest feedback on these 3 coil combinations,2 of the coils will be used alot especially the Coiltek one,must admit i am really pleased with that coil,its a pure pleasure to use,but its still early days and as the weather is turning for the better,then more detecting sessions will come along.

Happy Hunting 

Have you tried running the 15x12 commander mono on the TDI? I also have the ultra sensing 11 detech but I was hoping to not get the tiny bits with the 11 (I’ll save that for chasing gold) and maybe hit some larger deeper items with the commander when I want to use a lighter machine. I’m sure it would get more depth the the stock dual field 12.

Tyler,i have both 15x12 Commander coils ie DD and Mono,and was planning on using the Mono version on my TDI Pro but never did,it sat in its box for along time hoping that i would get a GPX at some time in the future,basically my TDI sits in the cupboard and no one would be able to tell the difference it is that good condition it looks like it came off the production line a few hours ago.

A few months back i was offered a basically new GPX4500 for a very low price as the seller had no idea,so i grabbed it and it came with a stock 11'' Mono and 15x12 DD coil,but i also had about 5-6 Mono coils that i purchased for using on the TDI,but it never happened,the coils have been used more on my GPX since i have had it and finally have my 2 favourite coils for my permission and use which is solely artefact and hoard hunting as i am not after nuggets here in the UK so i purchased a 11'' DD AI coil from Detech as most of my roman detecting is done on a site that has a massive pumping station hence the AI coil and it does work a treat,my 2nd favourite coil is my Coiltek 18'' Elite Mono and that on the 4500 does punch pretty deep on coins and much larger items and reasonably light as well.
