I was debating purchasing the new 5x10 dd coil for my F5, but decided to take the safe route and buy the 11inch spoked dd coil instead. I have used it twice since I got it and it is very similar to the Omega with a like coil. But, it does love and routinely ID bottlecaps in the same range as a clad quarter. A solid 80-82 from all angles. I have dug dozens in the two hunts I have used the coil. The stock concentric coil does not exhibit this tendency, but I will suffer with the caps as the 11 inch coil makes the already responsive F5 super at separation and depth. I can run my threshold and gain slightly higher and the six inch deep coins bang hard with the bigger coil. I really think the F5 is very similar to a Coinstrike and if my memory serves me correct, it's chief designer was also very involved with the Coinstrike. Mike if you are reading what are your thoughts. My main reason for this comparison is what the F5 does with deep nickles. It will high tone and give copper penny like numbers with an occasional 30 number. My three Coinstrikes would all do this. Shallow nickles will lock on with a medium tone and solid 28 to 30 numbers. I have found three Buffalo nickels with the F5 and every one had this weird quirk. All were in the six inch deep range too. After 50 to 60 hours on the F5 I am finding it to be an excellent coin detector and every time out, I am coming home with 40 or so coins. It really is a coin vacuum. R.L.

11 Inch DD Coil On F5
- Thread starter RLOH
- Start date
Sounds like the F5 and F70 are very comparable with the number readings on the TID. Those flattened bottlecaps fool me just a little every so often, sometimes I think it might be a tight spill, (never is yet). The unflattened ones are real obvious. Those Canadian pennies are the ones that bang in a little higher than a clad dime, and make me think "silver" every time. Copper pennys and clad dimes are soooo close! Its fun to try to guess if its a penny or a dime....depending on depth, a guy can get pretty good at the nuances of the signal. I think beach hunting is a great help to being a good dirt hunter, theres lots of bottlecaps on the beach, and easy to scoop, so once you've heard and investigated that signal a million times, you can pretty safely pass on it in the dirt, and focus up on the true beeps. I'm gonna go try out that F5 at my dealer I think...I bet I'd like it based on the posts here. If I get it with the 5" coil, Id be really set up right for all occasions.

My F5 will give me a high tone and a 66 ID on a silver dime to a max of 6" in an air test with the stock coil. After6" the signal is gone.
I'm trying to determine if my unit is faulty, or if that is the norm. was thinking about getting the 11 " DD, but want to make sure the detector is functioning properly first.
The F5 is fast and pretty good at separation, but the depth on mine appears to be sub par. I.m on my second set of batteries and haven't dug anything past 5" max.
Appreciate any help.

I find the break point on my f5 for Canadian pennies and clad dimes is 74 -75. 74 and lower is penny. 75 and up is dime. 79 and into the 80's is quarters, loonies and toonies.

Hi RL,
Hmmmm....CoinStrike vs F5.
Dimitar (may have misspelled) was the CoinStrike designer, while J.Anton Saad is the F5 designer. As far as I know, Anton did not work on the CoinStrike. I could be wrong though
The CoinStrike up averaged low conductors at depth instead of dropping them into the iron range. In high minerals, it would also raise the high conductors response. I coin hunted with the CoinStrike and learned to focus on number locks and not the number itself. If it locked, it was round. If it didn't lock, it wasn't.
To be honest, I haven't done enough coin hunting with the F5 to say yea or nay about it raising the id of low conductors at depth. My major focus with the F5 has been on jewelry, mostly small jewelry in hot ground. I'm glad you are coin hunting with it as we will all learn more about it. Maybe other F5 users can validate your findings. I'll try to when I get the chance.
Regards those bottle caps...some machines deal with them better than others. The F series with DD coils have trouble. Recognized, admitted to by the designers, and nothing more to do about it. I look at this way. Bottle caps are masking targets. I can't see below them until they are removed.
Keep up the great posts about a fine detector, RL.

Hi Turtleman,
Your F5 sounds faulty to me. I would recommend you send it in for a checkup.

Mike, thanks for the response. Yes, it was Dimitar and not J. Anton. The older I get, the more I think I am right, but that is not the case. Just ask my wife. I got out this am before the rain and came away more impressed with this fine detector. I seem to find coins much faster than I do with my other detectors. It is plain and simple a "fun detector". R.L.
I am persuaded that my style of hunting reduces deeper finds significantly. I go too fast and don't overlap enough to cover deep anywhere as well as shallow. I am in a hurry and looking to cover way too much area to do a proper job on deep targets. I suspect I am not alone. When I focus on a smaller area and tighten up, my finds improve. Applying that 24/7 is a bit like quitting smoking or dieting. Head is fine, heart is in the right place... body does not care. I know'd it was wrong but I do'd it anyway (as a great man once said a million times).

Tom, I really like the light weight of the F5, but everytime I use a light detector, I tend to go too fast. I have used Explorers since they came out and you have to creep them along real slow. After using my Explorer for three days straight, my F5 feels like a feather. I end up swinging it three times faster than the Explorer and I am constantly telling myself to slow down. The F5 can be swept fast, but I make my deeper finds when I slow down somewhat. R.L.

Hi, if your bottle caps are anything like our beer bottle caps are here in Finland then a quick sweep over the target will make their signal disappear while coins and other better items do not disappear on a fast sweep. This is a faster way of checking for them than using the toe or the heel of the coil and can be done without interrupting your normal swinging. I use this all the time with my F5 which is equipped with an 11" DD.

Interesting twist on the bottle caps- I'll give that a try! I've been saying, "Screw it." and digging the good signal without taking the time to recheck. It just seemed better in terms of gross production. I've been getting much better monthly finds lately. Next month marks my first full year MDing! It has been a trip!

Hello again, here is a short Youtube video I made last winter on distinguishing between a bottle cap and better targets. Discrimination is 0 in the video but if you set it to 15 or higher the steel bottle cap disappears even with a moderate speed swing. I have a habit of swinging just so fast that the caps disappear under whatever disc I have set on my F5. Really useful phenomenon.
