Eerste test resultaten van de nieuwe schotel;

Here are some tit-bits from my test notes;
Weight
Minelab Slimline (old SE coil) 600g
New Minelab SE pro coil 528g
12 x 10" SEF Detech 648g
15 x 12" SEF Detech 840g
18 x 15" SEF Detech 1034g
Depth
All targets were buried at increasing depths in a low mineralised (disturbed) soil to find 'maximum possible depths.' The Explorer SE was used at maximun sensitivity and the depths represent the signals where it was possible to say the target was positive.
Note: In real detecting situations depths attained here are only possible with great concentration by very experienced operators. It's one thing to detect over signals you know are in the ground, but another to find them when you don’t!
A cut quarter penny buried in clay soil (low mineralisation)

15 x 12" SEF Detech 11"
18 x 15" SEF Detech 10.5"
A crotal bell buried in clay soil (low mineralisation)
Minelab Slimline (old SE coil) 15"
New Minelab SE pro coil 15.5" 12 x 10" SEF Detech 16"
15 x 12" SEF Detech 18"
18 x 15" SEF Detech 19" *
(*possibly would've gone deeper but I gave up as the hole I was digging was getting silly.)
As you can see the larger SEF coils perform better on larger items but as expected lose depth on the smaller items.
Noise
The new minelab coil was the quietest followed by the 10x12 SEF (and the other SEFs close behind)… the old slim-line is the noisiest with strange threshold warbles coming in at high sensitivity (which increased and started popping when the coil got wet.)
NB de Diepte scheelt dus maar een paar cm, dus daar hoef je het niet voor te doen.
