What coil to choose

What DeepTech’s metal detectors coil to choose Eddy Rondags is metaldetectorist from Belgium and already a year maybe his unit is Vista GOLD. He own, if I not make mistake, five from DeepTech’s metal detectors coils for this unit.

The 8” closed design coil is new for the market, so hope Eddy’s observations and recommendations will be helpful for many from you, our clients.

Coil Advise: What type of coil to Use when??

By Eddy Rondags on Sunday, February 28, 2016 at 1:45pm

It depends a lot of field conditions and wich kind of objects you prefer to find: at roman & medieval settings or near village centres it's mostly devestated with small iron, coals, and even iron containing pottery: in that case i will choose my 8". It also has a very good bite at the smallest objects....

I'm a typical medieval/roman hunter so i love the tiny things..... military is mostly larger and more easy to find so their benefit will be the highes possible depth.....Also at harvested corn fields, were rows of cornstabbles remain behind: its very comfortable to swing between with this small and manouvrable coil.: It doesn't weight anything: in summers with hot temperatures and long hours... i wil use this coils or medieval and roman hunts. It still goes very deep. I 'm hunting at 17th century battlefields, or at 15th... 16 century coins, WOI or WOII relics which are mostly larger objects i will use the pitbull. More stability in ground balance means more depth in the field: for larger objects You will experience a benefit in that way.

Some Field types whit steep hills are more unstable groundtypes so there i'll be better off with the best stabil coil such as the pibull coil.

You have to think about it.... and balance for yourself what's suits you the best at each field our soiltype.

Everyone knows these fields: with a large coil it's very clumpsy to manouver between those rows. The 83 is an ideal coil size to track easely between the rows: it's my number one tool at all those types of fields regardless the objects i'm loooking for: so the 8" is adviseble for customers who live in ares were cornfields are the primary farm output: they will love it

Unequal, unflat fields.... for example in tractor tracks like this: The 8" is small light and very quick to angle or rotate with almost no weight at the whristles or shoulders: so it has a very important benefit at those types of fields. As you can see a larger coil will cover twice as much unequality because the bigger size of the coil: this reflects in in Twice as much groundshutter caused by all this depth difference. As a result you will have to raise groundbalance more which cause depth. A small coil less seperated tracks will give less ground shutter... that's the idea behind it

The 8" coil is closed : All the other coils are open..... When hunting at these types of fields: the water containing stabbles get stucked in our open coils: which is very frustrating. With the new closed 8" inch this problem is reduced a lot and because it's smaller you can easely swing between the seperated stabbles so also for this type of vegetation i will use the 8" regardless which objects i'm looking for

Flat fields/grasslands..... here it depends of the ammount of iron/coal: when less coal/iron you can go at fully depth benefit with the Pitbull coil, or the 14"..... Finding larger coins, or objects at fields further away of town centers will be easier with depth coils like pitbull or 14": they also cover more square surface so you cover more land in less time: Also for quick scanning new fields i use my pitbull to find out if that fields contains many coins or not.... but i don't recommend it when hunting specific at tiny objects. Because you get the crvaing to walk faster and miss all the tiny things ver easy with the larger coils. In iron/coal areas i choose again for my 8" because it has no iron masking an the signal recovers the fastest of all coils, straight after hitting a coal or small nail it recovers, while larger coils hold the iron object longer in memory because the coil is bigger the iron object stays longer under it. In areas with lots of objects close near eachother this is very important.

White sand/ kempen: this type is very loose (not like heavy loam soils) for my opinion objects sink deep away in sandy soil types..... logical you use a coil that generates the most possible depth like the Pitbull or 14"

In the woods: the same problem: lots of small trees, plants, roots, stones..... unequal areas with lots of obstakels: There you'll have the most benefit of a light, quick, and very manoeverable coil, so here again i wil use the 8"

Lots of fields with large High/low variations are more unstabil ground types from nature. At those conditions i'm better off using a more stabil coil like the Pitbull. But you have to balance for your self if you gain more with the best stability or more with 8" when large amounts of iron are on that hills.....

Flax fields: After harvested you will have large superflat fields: the most ideal fields to hunt at. In the first place these flat fields will be very stabil ground area's to hunt. But! After a few weeks lots of small weeds will grow at it from flax seeds that come out again. These littele weeds will containing a lot of water and moist. Especially by dawn. This gives also extra ground shutter too so in this situation to reduce this extra ground shutter and gain mx. possible depth.... i will use my pitbull again. Accept when the place is iron and coal infected.In that case i have to overthink which gives me the best possible benefit
