help- which coil?

Post by ikaruz »

Hello, i have the xp deus with only the ws4 headphones and the 9" hf white coil, so... its the deus lite. a few days ago i updated the detector with the remote control of a friend, so its in the last version of software.

in the past i had the 11" coil, but it became faulty.

i have some places with some medieval coins, and roman coins where i get some coins a little deep with the hf coil, and now i need a deeper coil.

so... wich is the best choice? buy a used one 11" or 11×13 coil, for something around 150-200€, or buy a new x35 coil? does it worth the x35coil?! or the old coils are enough?

i have a third option, buy a used detector with a price around 300-350€.

so... what is your opinion? and wich is the best option, and why?

thanks

I would stay on the 9" HF coil, and get myself a controle unit..

Can’t comment on the x-35 series, but the 9 inch standard coil is as deep seeking as the 11 inch standard.
The 13 inch is rubbish , don’t ever go down that route .
Ground coverage is the same with the 9’ and 11’ as the lighter 9’ swings a bit faster so covering the same area as the heavier 11’
Also, the 9’ coil pinpoints and locks on better than the 11’
The smaller coil is a joy to use .
Bigger isnt better with the do deus , it’s just another way they temp you to part with a LOT of money . ::g

I personally don’t believe going 25khz or higher has any advantage over standard 17khz on the uk low mineralisation soils, our uk earth is iron laden and 17khz is ample for separation .
Saying that, I will be buying a x-35 9’ coil when I don’t have to sell a kidney to afford one ...just to see if my hunch is right .... or not :))

I'd second the X35 11" coil. ::g

To get greater depth, you'd need to use either the Hot or ultimate programs, based on the Deep program. I'd drop the frequency down to 11khz, keep the coil as low to the soil as possible and swing slow. This will be picking Roman and Medieval coins up at a depth of 10-12". Caveat - depends on the ground conditions.
With the X35 coil, you could also try taking the frequency down to lowest - 4khz, offsetting it down further to 3.7khz then using the boost function. Increase the sensitivity as high as your ears can stand - you may miss some very small finds, but you'll get some great depth, and won't be missing the silver.
Good luck

As touched upon by Pink Floyd above, don’t be too taken in by the bigger coils/more depth thing. When i see people using really large coils like those 17inch Minelab radar dishes i have to stifle a hearty guffaw. Larger coils might be better for detecting large masses at depth, but on coin sized items, which lets face it, will be what most of us are looking for, there is very little difference between the 9,11 and 13inch coils.

If you have it on good authority that there might well be a hoard, buried weapons or a stash of axe heads on your sites, then i can understand using a specialist tool for a specialist task, ie one of the radar telescope type affairs that you see people brandishing more and more these days. For everyday use though? I think the larger coils offer a lopsided set of attributes, they might be beneficial for a specific task that involves looking for large masses, but beyond that i am not convinced they are beneficial.

I bought my Deus with a 9inch X-35 coil a year ago. I love that coil. It makes the balance and feel of my machine a thing of beauty, with no fatigue on my wrist even on longer hunts. This coil also hits harder on targets, due to its search field being narrower and thus more concentrated (think of focusing the beam on a torch, same thing). It is an absolute cinch to pin point targets too, even if you are using the old school methods like backing off of the target till its on the nose of your coil. You can also get this coil into tight spaces easier than its bigger brothers.

I recently bought the 11inch X-35 coil, as i expected it does not offer much more depth than the 9inch on small items. It might offer an edge in depth, on say, a hammered coin, but no more than that. The weight of the 11inch X-35 is the same as the 9inch version, but it has a greater spread, so its by no means weighty or a wrist breaker, its still a very light set up, but it does change the balance and feel of the machine a bit. It does give you that extra coverage which can be helpful on larger, less target rich sites though. I am glad i bought this coil, it has added something to my armoury, i have another coil if the 9inch has to be repaired for example, and i do like the extra coverage, but i can’t say i like it as much as the 9inch version.

Personally, i would not be interested in the 13inch sized coils, and i find coils made by other manufacturers that are even larger to be nothing more than a source of amusement. No doubt the 13inch coils would make the Deus a bit too front heavy for my personal taste, plus i am not looking for dustbin lid sized targets generally. I am looking for older coins, jewellery and the like. The 9inch coils, with settings tweaked to best effect do a good job on this front.

The standard and X-35 9 inch coils, in my view, are the secret weapons in your Deus armoury. They offer a more rounded set of attributes. They might not be as fashionable as the radar dishes that are currently in vogue, but i think in general terms they do a better job. Just my tuppence on it...

You can say that again :D


I often think about getting the x-35 series , but I’ve not bought one .
My 9 inch standard coil dosnt miss anything at 17khz , and I still can’t get my head around why go higher frequency when we in the uk don’t need it

I was with you, going higher should loose depth as well, I thought. However I’ve been doing some experimenting. On ~17khz I had a signal a few weeks ago I got a repeatable but feint signal. Switched to 28khz and it transformed into a good strong, obvious symbol. It was a very worn, thin hammered penny at a around 5” depth.

This was with the X35 11” coil. So I decided to keep it on 28khz for a whole session and am regularly digging both small targets and deep finds too. It’s not ideal for a site with a lot of lead, as it loves lead at higher frequencies, but on clean sites it is incredibly versatile. I see no point using frequencies below 17khz now.

I wish you could try an X35 and you’d get why users of them love them. I hated it before v5.21 came out cause it wasn’t working right but it’s now a dream to use. The HF coil only gets used occasionally, on iron infested areas mainly, to get better target separation. But if you go higher than 28khz the coil can get very sparky.
The 11” X35 gives better coverage, is very balanced and delicate enough to find tiny targets in everything but the most iron infested sites.

If I see one going cheap, I’ll pick it up and give it a go .
The 9 inch that is , I’m used to that :))
