okara gold Posted May 19, 2021 Share Posted May 19, 2021 I've been using the 8 inch coil exclusively in the salt water for about 18 hours now. It is definitely quieter than the 12.5 inch. I am running with a delay around 8 or 8.5 and today 9 because of some bigger swells coming in right up against the shore. Played around with some higher delay settings and things quiet down even more. If walking parallel to shore in the water, there is still some "noise" when sweeping from the shallows to deeper water as can be expected. Coming back from deeper to shallow...all is quiet. Coil sweep speed and height control still play a key part in keeping the threshold smooth. It seems more sensitive to smaller objects and some iron will still give a double blip in all metal. Sensitivity was set at 6 and ATS around 5. I'm wondering... Say you run the big coil with a delay around 11 and the small coil with a delay around 8... which one would have better punching power on ring size objects? 3 2 Link to comment Share on other sites More sharing options...
dewcon4414 Posted May 20, 2021 Share Posted May 20, 2021 Bob. Some of that noise if you are hunting our local area is bit of iron stone. Gets caught up in the mass amount of seaweed we sometimes get ... and having high bank shore lines don’t help. A good many machines will false running across the grain. As far as the Us....keep in mind a majority of PI used in the salt water have a setting 15 Us and above. So you have some room to play. Good to see you are back out there with the machine. 1 Link to comment Share on other sites More sharing options...
okara gold Posted May 20, 2021 Author Share Posted May 20, 2021 Hey Dew! Thanks for responding. It is good to get out again after some long setbacks. I see things are still sanded in pretty good too. Took the AQ out today and used the 12.5 inch in the water. Big difference in usable delay between the 2 coils. Will probably go right back to the 8. Hope to see you out there. 1 Link to comment Share on other sites More sharing options...

Can you explain what you mean by "height control" more? Also does sweep speed mean, slow? Link to comment Share on other sites More sharing options...

Height control is trying to keep the coil the same distance between it and the ground. If you swing with a tendency to lift and lower the coil even a little... then you will have false signals and or an increase / decrease of the threshold pitch. Same with the sweep speed. Try to keep it consistent and a little slower than you would with a VLF. In the water this is more difficult to do but the more time spent the better you get. 5 Link to comment Share on other sites More sharing options...

My opinion, The little 8 holds up very well on depth against the bigger 12.7 on all gold targets. But I still feel the Big coil is the best opp if you can keep the noise down on gold rings. One thing I have noticed about the AQ, No matter the (below) settings in All Metal, depth lose is very minimal. Running high to low sensitivity (4 to 9) and the ATS from 0 to 8... then the Delay 7 to 11. Water here is Brackish and not as bad as the Ocean salt, then rushing waters......... so I do feel I have a advantage to more opinions on settings with the bigger coil.. one reason I may sell the little coil n shaft. 3 Link to comment Share on other sites More sharing options...

I’ve used the big coil in 2 different brackish water locations in Florida and comfortably run the delay 7.5 to 8. Very minimal falsing. Should be a killer in fresh water. I did play around and lower the sensitivity a little today. Worked fine. 2 Link to comment Share on other sites More sharing options...

If the coil is on the ground, why would one have to worry about the height of the coil? Link to comment Share on other sites More sharing options...

If the coil is "on" the ground how would you move it side to side? It has to be elevated somewhat in order to move it side to side unless you scrub the coil against the ground without ever lifting it. By keeping a constant distance between the bottom of the coil and the ground you achieve optimum results. 3 Link to comment Share on other sites More sharing options...
