New Coiltek Coils for Equinox

[AceofBases]

Exciting news yesterday-- while the Equinox Smart Coils are great performers, many of us have been looking forward to adding some new tools to our arsenals.

So, now that they're announced:

• 10x5 (DD)
• 14x9 (DD)
• 15" round (DD)

To our resident experts: what is the coil that's most likely to bring something new to the toolbox from a performance perspective (more depth, more selectivity in higher trash areas, etc.) due to its construction/orientation?

I'm no expert but I'm interested in the 10x5, to work around the corn stalks and bramble.

10x5 looks like a great alternative to the 6 inch with decent 10 inch swing coverage and equivalent or slightly greater depth. The devil is in the details, and if you do the deep dive you'll find the 14x9 was weighted intentionally for water hunting. At 880 grams it is slightly HEAVIER than the 15" round (836g) and 220g heavier than the ML 15x12 (660g). On a nose heavy detector, no way I would consider the 14x9 for land hunting, and even the 15" seems like a load for the inch or two of depth, max, it might have over the stock and the 15x12.

Cool, I'll look forward to the reviews on the 10x5. My arm gets tired with the stock coil (bad shoulder), I find myself wanting something between that and the 6" for non brushy woods.

Is it me or are those coil ears bending inwards on the stock photos? That's a bit unnerving if they are.

Dang!! I really want an 8" round coil!!

Good points there, vferrari, on the coil weights. Did you happen to see the weight for the 10x5?

Coil Weight and Footprint Specs for comparison:

ML 6" round: 300 g, 6" wide, ~28 sq in., AWR ..093

Coiltek 5x10" elliptical: 426 g, 5" wide, ~39 sq in., AWR .092

ML 11" round: 510 g, 11" wide, ~95 sq in., AWR .186

Coiltek 9x14"elliptical: 880 g (!), 9" wide, ~99 sq in., AWR .112

ML 12x15" elliptical: 660 g, 12" wide, ~141 sq in., AWR .214

Coiltek 15" round: 836 g (note this weighs LESS than the 9x14), 15" wide, ~176 sq in., AWR .211

AWR = Area/Weight ratio in sq. in/g = subjective measure of performance per unit weight. Really only good for comparing coils of similar dimensions. As you can see the small, and large coils are fairly similar in their AWRs. Notice, however, the 9x14 weight and AWR which is really low compared to the 11" round and its total weight is GREATER than the 15" round coil. The reason for the discrepancy is apparently Coiltek added weight to the 9x14 to facilitate submerged water hunting (discussed in the Coiltek link below). Certainly takes it out of the running as a substitute for either the 11" or 15x12" ML coils on land. If you want raw depth and good coverage on land, go with the 15" instead. If you just need coverage and slightly better or equivalent depth to the stock, go with the 15x12 which weighs more than 220 grams less than the 9x14 despite having 1.4 times the footprint.

That's what I'm thinking as well.

Thanks vferrari and ripvanb. So, the 5x10 falls roughly halfway between the 6", and the 11", in terms of weight. Not bad...

If it turns out to be less fond of nails than the 6" coil is, looks like I'll be buying one.

Yep. I am already on the list for a 10x5. Not interested in the other 2 coils.

 

[relicmeister]

My choice would have been 8” or 9” round, or same as the V10 on the Vanquish 7”X 10”. If reports on the 5” x 10” are really good, then I’ll consider getting one.

 

[AceofBases]

No interest in the 15” round considering it may have the most depth of all available Equinox coils? For that reason, it piqued my interest.

 

[Digger RJ]

As long as the problem with the ears have been resolved on these coils, I see some nice additions to Our arsenals. I'm going to pick up the 10x5" when it's released. I had the 10x5" for the CTX, and it's excellent for residential yards. I had actually found coins I had missed with the stock CTX coil. If this one is as good as it, then it will be a very nice addition.

What depths were you getting with the 10x5 and CTX? Did it approach what the stock 11" coil did? Thanks.

If the 15" round will get more depth without losing small target sensitivity, I'm in. Any added depth at the beach is a good thing in my book.

I primarily hunt in highly mineralized sites, larger coils are simply counter productive since they see so much of the ground mineralization. Plus the weight of the 15" round is 220 grams more than the 12x15. The Equinox is optimized around the stock 11-inch coil, as a result that 15" coil might get you some additional depth perhaps one or two inches at most under ideal conditions. You simply have to decide for yourself if that amount of weight is worth it for the off chance that you might actually find something beyond the (soil and target dependent) 10 to 14" depth limit of the 11" coil. Probably a good beach coil if you can stand the weight, though I've dug nickels to 15 inches in wet sand with the stock. Too much coil drag to swing that beast in the water. Thst's what Coiltek made the weighted 14x9 coil for.

I think they designed the ears that way to counter side loads
