Four inch coil...

[matthias]

Anyone have one of these coils and find you are using it a lot more than you ever thought you would? I am. Great coil with a great advantage over larger coils since it can get in tight spots. What are your thoughts about this coil? Just curious. HH. Matt

I've much enjoyed the 4" coil in trashed out sites. I use it on a BH Pioneer 505.

Along the Salmon River, many camp spots with or without some kind of development like tables, trash cans, and or out house, are pretty well trashed with about all you can imagine. Shell casings, pull tabs, fish hooks, foil, tent stakes, aluminum cans, old bottle tops, lead sinkers, and worst of all, melted aluminum from an over abundance of old scattered about fire pits. Seems like everyone has to have their own virgin fire pit than to use the one already existing. Much of this stuff below High Water also migrates into the river through flood action. You would not believe the size of some metal a person can find in this river. At the Hammer Creek boat launch and camp ground below White Bird Idaho, a person collected various pieces of metal and trash found in the river from the lower more remote part of the Salmon and built a trash sculpture out of it to point out how much junk can be found.

Back to the 4" coil though, it is a great help in trashed out locations and tight spots. You do have to discipline yourself to tighten up the overlap a bunch and be patient enough to not expect to cover as much ground as you could be accustomed to with the standard or larger coils. I do believe it is a more sensitive coil to smaller items and I think a little depth is lost depending on mineralization and machine settings. Because it does not weigh as much, you must also remain conscious of your swing speed so to remain as constant as possible. I do not regret buying and using it. Of my 4 machines, I have equipped 3 with the smallest coils available for them. One of those is not a round coil but is an elliptical so it is used a bit differently than the rounds as it is mainly limited to only side to side swing though I fudge it a bit at times getting up to about a 45 degree angle out away from my front that reduces my coverage even more but still get hits on things without having to completely reposition myself to get another angle. The round coils you can move toward and away from your front.

Hey Salmonriverhotrock... Thanks for the reply. As I look at my 3 machines I notice something odd, too. They all have tiny coils on them! You are exactly right when you stated that the 4" coil is more sensitive to smaller items. Do I own larger coils for my 3 machines- yes. In my opinion, and for my soil conditions, I seem to rock with 4"-6" coils. The point of all this, if there is one, is that my Bounty Hunter 505 Pioneer with the 4" coil rocks. HH. Matt

Depends where your hunting on coil size.The less trash the larger the coil. That is if you have the arm to swing them. I had a 4" on 1 machiine and it rocked. I can bump metal poles and backstops and pickup coins dead agaist them. I also use it to "Power Walk" and have lost 10lbs so far. I briskly walk( knee pads and all) around soccer or ball fields and if I hear something I stop and recover the area. Not looking for deep. Sometimes I find too much to get a good heart rate from walking. Wondering if I could get someone to make a 4" for a MD that the smallest available is a 5.75?

I like the 4" in brushy areas, streams and under gymsets at playgrounds. To hunt the woodchips under the climbing bars where there's often many targets in a small area, I leave the 8" coil mounted to the detector, but unplug it and plug in the 4" coil with no stem attached. I freehand it like a pinpointer while sitting on the chips.

Finding a bunch of quarters in one spot gets the heartrate going just fine!
