Walked down to the local watering hole; brackish water bay tributary, pretty well cleared out over the years but a bit trashy with bits of iron. Ran delay 7, sensitivity 7, threshold 4, volume 8, ATS 6.5, reject 6; mostly all metal but some tones and mute to check targets.
Initial reaction is that it is a little easier to hear the edge modulation with the 8 inch than with the big coil. I walked away from several targets that were very pronounced double tones then had a more subtle edge that I told myself to walk away … but dig to verify. That was the little fish hook. The odd shaped washer, to the right of the fish hook, fooled me; it sounded pretty good in all metal and in tones. The rest of it is all non-ferrous. Some of the small targets fell through the scoop several times before I finally capture them and got them in the pouch. This set up finds fairly small targets well. Tones seem to be more pronounced to me with this coil than with the big coil with some similar settings, yet I think I still hear iron better in all metal than in tones ... maybe some setting tweeks would change that around but I'm pretty happy in all metal.
I did have an interference issue. A boat about 100 feet from me fired up and the AQ talked and talked. Stepped through the frequencies and no help there. I was shallow enough the detector head was above water so I went deep where the detector electronics were well under water and, surprise to me, that did not help either. Dropping the sensitivity down to 2 made it usable. Once he lowered the boat lift, backed off and motored away I could turn the sensitivity back up and hunt with a very quiet AQ.
Did have a great blue heron land on the beach and walk into the water. Got about 30 feet away from me so I stayed still and watched it turn its head looking for minnows, catch and eat them. After a few minutes it walked around the beach corner towards the boat lift then flew about 2 hundred yards down the water.
A good afternoon in the water.
Didn't get out this past week since I was under the weather.
Started out with the detector being really unstable. Water got into the coil connector. Blew the water out of the connector and tightened the back-shell and everything was good to go. I also have noticed when I'm in shallow water she's a little noisy and a lot of falsing (water way below the connector). She's pretty stable when completely covered. I do run my machine hot in all metal.
One old beach I hunt always has sand piled in to the one side. No sand movement in this area other than more accumulation. For years I said there has to be targets just out of detection range. Well not for the AQ. I did find a few targets in this area. I had to work slow since these targets were pretty close to the depth limit and I was running hot. A few pieces of crusty Silver and a nice 10K ring dated 1946.
Really liking the audio information of this detector. If anyone wants to look around there's a great video on the reactivity that shows what it will do. Seeing this showed me how differently the machine is responding well to elongated targets if you change your sweep direction, "feel" around and listen for the double tone or anything that is not centered. For a pulse I dig very little with this detector. While there are certainly hoop earrings, crosses and other targets that would probably sound similar, overall the potential is there to really develop some accuracy. I also like how it "discriminates" between non ferrous and anything that's blending into the ground--including caps (wide / narrow). My beach is very sanded in now but the potential for getting 20" gold with this machine is very exciting. The video shows that its a detector that learning and using your basics with will pay off.

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?
Hunted a few hours with a good friend today. Half of the hunt was in All Metal and the other half in Tones Mode. I dug everything today trying to learn the machine. Those Corona caps became predictable in Tones Mode. All Metal seems to run a bit more stable and punches really deep. I originally thought the piece of a bracelet I recovered was junk until the 10K stamp was pointed out. No sign of the rest of it in the area, but Ill take it.
This is an update on the lower shaft that snapped into two pieces on a Sunday morning wet sand hunt on April 25. I list events in a timeline.
Sunday April 25 about 10:00 AM the lower shaft broken into two pieces after 30-45 minutes of detecting in the wet beach surf.
Monday April 26 in the morning I emailed First Texas with pictures of the broken shaft and received a RA from FT and shipped it back to FT Monday afternoon April 26. I posted a message on the Impulse AQ Facebook page pictures of the broken shaft an received a reply from Russ Balbriona that said “Hello Joe- Russ from Fisher here. Email me firstname.lastname@example.org. I'll get you taken care of.” I also posted on here at DetectorProspector a post with pictures and received a response from Alexandre that said “Thank you for you feedback. We are ready with the Mechanical Team to understand and solve the problem. A lower rod will be sent to you in exchange, and we are studying the phenomenon. Tests are already carried out internally with high lateral pressure, we will continue in this direction to understand. I contacted the whole team when I san the message today.
Thursday April 29 at 10:23 First Texas received the broken shaft which was signed for by someone named Mocosta.
Friday April 30 at 3:47 (on the beach detecting with my Equinox) I received a call from First Texas. At 4:05 I received an email from Felix at First Texas that said “We just received your lower tube and is being analyzed by our engineers/quality and will call you on Monday to follow up with you – stay tuned.” And that my voice mail was full. (it did have one 22 second message about my car warranty in it)
Monday May 3 I called Felix early as I had an appointment later that day and he said Engineers/quality would decide IF they would replace the shaft under warranty.
Today Monday May 10, 16 days after the shaft broke, 15 days after First Texas was made aware of the break with pictures and responded to me, and 12 days after First Texas had the broken shaft in their possession.
So the update is “there is no update”.
