F5 Coin Vacuum

RLOH

Well-known member
Every couple of days I will take a break from swinging my heavy Explorer 11 and use the F5. When I come home and total up my finds, I am always amazed at how well I did. Today was no exception. Three hours of detecting produced 35 coins of which there were 7 wheats and two mercury dimes. It is my practice to hit four spots at least once a week and today's spot usually does not give up many older finds. This place has been a park since 1960 and had a school sitting on the property from around 1900 until it was tore down in 1959. My oldest coin from this spot is a 1865 Indian head. There is a long winding road that cuts through this park and it must have been paved with the slag from the old boilers as it drives most every detector I have used crazy. You can barely tell that it is road as it has spots of grass covering about half of it. The F5 was chirping away when I started hunting this am so I immediately reduced the sens to 55 and the threshold to 0(usually hunt at 1) The Fe meter was running with three or four bars blacked out. The ground phase was in the 80's and with the lower settings the F5 ran relatively smooth. For the record, I have never found a coin on this roadway any deeper than 5 inches with any detector. The F5 started barking out high repeatable high tones(I hunt in three tones) like it had never been hunted. The wheats were all 4 to 5 inches deep which is outstanding. One of the mercs was only two inches deep and the other about three inches deep. I finished the road and hunted around the pavilions and was dumbfounded how the F5 was picking up coins. There was a festival here the end of July and the locals start hunting before the tents are down so the coins I found were nowhere near the usual surface drops. I have found the coins deeper than 6 inches will lock on a high tone, but the numbers will usually run higher when I walk around the signal. For instance a 6 or 7 inch deep wheat will read correctly(high 60's) from one angle but will jump up to the high 70's with the tone remaining constant. This is not terribly unusual so if you are looking for a hard lock on the numbers, dig the repeatable deep high tones that don't stay consitant with the numbers. I am going to buy the 11 inch dd coil in the future which should help me with the hot ground where I hunt. This is a sweet little detector and I could not be more pleased with it. R.L.
 
Good post RLOH, I agree with you.

If you don't mind me asking, you mention getting an upgraded coil - I've noticed they're few and few between. What other coils are compatable with the F5? I'd love a big DD but there's no mention of large compatible SEF or DD coils? Any ideas or proven types?

Cheers
 
As far as I know there are no aftermarket coils available like the sefs. I will buy the Fisher 11 inch dd coil. I had an Omega with the 11 inch dd coil and it was an awesome setup. I have a gut feeling that the F5 will be very similar in performance with the Omega setup. I like the screen and the knob adjustments on the F5 compared to the Omega. They are both nice detectors. One thing for certain, the F5 stock elipptical concentric coil is spot on in identifiyig modern trash. I will go so far to say it is one of the most accurate detectors I have ever used. I dig hardly ANY trash. I am hoping the dd coil will stay close to the concentric with it's accuracy, but sometimes that is not the case. R.L.
 
You might get a little rise in the digital read out but since i changed to the 11" DD coil i don't use the 10" standard coil at all. It works good at the beach as well as at the parks. More coverage at the beach is a big help, pinpointing is very accurate and the balance to me seems a lot better with just a little bit more weight on the front. I don't think you will be sorry for purchasing the 11" DD coil.
 
Wonder if F5 is light enough for my wife.
AT Pro she wont swing.
Even Ace 250 tired her. After 4 hours mind.
