10" coil ?

[Rebel1]

Does the 10" coil offer any real advantage over the stock 8" coil?

The 10 inch coil has both positive and negative characteristics. You can cover more ground with it, and it added an inch or little more of depth on larger coins, quarters and half dollars, but it seemed to be weaker on dimes and missed a lot of coins because of masking where there were a lot of trash targets in the ground. I use a 10 inch coil on another brand often, but only where there's relatively little trash or hunting large areas when time is a factor. I go the other way more often by using a 5.5 or 7 inch coil, and have found far more with those than with larger than standard coils. The 10 inch coils are worth having, but I wouldn't consider one as a primary coil.

Thanks JB. I have the 4" but haven't even used it yet. Guess i need to give it a try.

A few years ago I bought a Fast Tracker at a local pawn shop for $20 and got a 4 inch coil for it. I found enough coins with that combo to more than pay for both the detector and coil in just over a month. I set the sensitivity low and was able to hunt right up against the metal fences around the athletic fields here. I hunted both inside and outside the fences and the number of coins found was pretty amazing, and also got two silver rings and a silver Teddy Bear about 3/4 inch long. Nothing else we used before or since could get close enough to the fences to get the coins. There's a playground that was built on top of what had been a city dump, every detector we tried there, even with coils as small as 5.5 inch and running low sensitivity, detected the trash underneath the playground which masked the coins, but again I set the sensitivity to a low level on the Tracker and while it also detected some of the deeper trash it also picked out darn near half a gallon bucket of quarters, dimes and nickels. I traded the FT to a neighbor for his 8 year old to use and sold the four inch coil, but should have kept both. A detector that has good depth is good, but like a sledgehammer they're not always the best tool to use .

Thanks again for the additional info JB. I guess i better head to the park tomorrow and try out that 4" coil on the Land Star. It does appear in air tests to get nearly as much depth as the 8" coil does.

The 4" coil works BETTER on my Tracker IV and has more depth in the nickel/tab range where it counts-to me. Part of the problem, as JB pointed out, is the weak signals with the bigger coils on small objects.

 

[Rebel1]

Well, i have the 8" and the 4" so i guess that will do me. Still need to get out and try out that 4" though.

the 10 inch coil is for relic hunting, etc. and has done a good job for me. you will also really like the 4 inch coil, it has found 2 rings and more in the little time i used it.

I am very new to metal detecting and as yet have not done any field or beach work.I live in Cyprus and have already found out the rules and regulations on using my detector on this island,but I would really appreciate any tips or comments from anyone. I will be using a Bounty Hunter Discovery 3300 with 8 and 4 inch coils,with the possibility in the future of adding a 10 inch coil, thanks branian.

10 INCH COIL COVERS MORE GROUND FASTER WITH SIMILAR RESULTS TO SMALLER COILS
USED ALL SIZES BUT ALWAYS PREFERRED THE 10 INCH BY FAR
SEPERATION BETWEEN TARGETS IS STILL VERY GOOD
PINPOINTING IS NO PROBLEM
