Profind 35 And Nokta Green Headphones Interference


Recommended Posts

I did some river hunting and descided to take my MK out with the waterproof wired headphones and my ProFind 35 pp for piking through the river clay as it is waterproof. Left my PI machine home because the power lines make it impossible to use in the stretch of water I was hitting. I realized that the Profind 35 does not effect the MK in any of the frequencies at all with the wired headphones. The green wireless ones go bonkers with 5 and 14khz modes with that pp and I can only use 19khz with them.

Strange how the bluetooth headphones react with the profind. I always assumed the interference was with the coil or control box and not the headphones. In park hunting I had gone back to my old Whites Bullseye pointer as it plays well with all my machines regardless.

The Nokta/Makro wireless headphones are 2.4ghz, not bluetooth, so that may possibly have something to do with it.  I think TNSharpshooter mentioned something a while back about pinpointer interference on a Nokta/Makro detector, though that was via the coil, and not being picked up through the wireless headphones.

Strange how the frequency of the machine effects the headphones. I would have thought that the headphone reception would be the same regardless of the machines settings.

Doesn't the Multi Kruzer have a wireless frequency channel adjustment? My Gold Kruzer allows me to pick one of twenty different frequency adjustments so that there is little or no interference encountered between the green wireless headphones and the 2.4 gHz transmitter in the control unit.

It does but makes no difference. Odd part is why does the headphone connection have to do with anything between the coil and control box that is hard wired? Not knocking either devices just curious.

Coil to control box at XX frequency should not efffect an audio channel on a headset ESPECIALLY if it works on one frequency, why not all?

So you are saying that you only get interference through using the Profind 35 and the Multi Kruzer on 5 kHz and 14 kHz just when you use the Green wireless headphones and that the interference is not coming through the coil. Do I have that right?  If that is right, changing the wireless transmit channel should help. 

So you have tested the Profind 35 in a low EMI area with the Multi Kruzer in all three frequencies with just the internal speaker, with wired headphones and with the wireless headphones and the only time there is interference is with the wireless headphones...........  weird.

Ya the only time it interfiers is with the wireless headphones. I'll try changing frequencies and see if that helps. I wonder if it's the DIF on the PP causing the issue.

Buddie has a PF35 and can't come within 5ft of me with my seahunter or my sh freaks out.

Tested with different frequencies and makes no difference. This has me stumped.

      I've been debating whether to get a Fisher F-Pulse due to its greater sensitivity compared to my Garrett Carrot. But I wonder about its "closing range." What's that? Let me try to explain.
      Today, I tried using my Garrett Carrot for a full hunt, but had it on maximum sensitivity. I appreciated its extended range as it made it easier to determine if my target was in my plug or hole. However, I realized that the greater sensitivity isn't as useful as I had hoped given the amount of trash where I hunt. So while my Fisher F2 could discriminate out trash, during my dig, my Garrett Carrot might detect a piece of trash before it could get the actual target I was digging for.
      But I confirmed that the greater sensitivity of my Garrett Carrot isn't as useful as I had hoped because of the short "closing range" it had. What I'm referring to is its ability to change its beeping as the poinpointer gets closer to the target.
      For instance, the pinpointer might detect a target 3 inches out. But when it's still 1 inch away, the steadily increasing beeps have stopped and now it's a solid tone. And it stays this solid tone no matter how much closer you get to the target. Ideally, the steadily increasing beeps (what I'm referring to as its "closing range") will continue until the pinpointer is touching the target.
      I see tons of videos on a pinpointer's sensitivity. But none on its "closing range." I'm realizing that having a pinpointer with the ability to detect a coin at 4 inches, but only has a "closing range" of 2 inches may not be as useful as a pinpointer with the ability to detect a coin at 3 inches, but has a closing range of 2.75 inches (assuming this kind of pinpointer even exists). I also understand that the size of the target makes a big difference. With my ring, I may never get a solid beep from my pinpointer even when it touches my ring. Yet when next to a metal trash can, I get the solid beep when the pinpointer is 4+ inches way.
      So my question is: what pinpointer(s) have the best closing ranges? For example, the Fisher F-Pulse has the best (or among the best) range/sensitivity of most major pinpointers on the market. But does it have a correspondingly long closing range, too?

      I recall that there were several people here who were looking for the TRX pinpointer and not finding them in stock anywhere. I was just looking at the Centreville Electronics website and they have them listed in stock for $199 with 2 year warranty. I was able to add one to my cart so it appears real.

      Hey everyone! I just upgraded to a nox 800 at the start of the month, moving over from a simplex and pulsedive. I was having trouble getting used to the nox at first and was thinking of sending it back because I couldn't even detect in tot lots. Thanks to some posts on here, it's going a lot smoother.
       
      My question is this, is there a way to pair the pulsedive with the equinox headphones?

      This morning I wanted to charge my XP MI-4 pinpointer but couldn't open the knob covering the charging plug. After many fruitless attempts, I contacted XP service at metaldetector.com. In an on-line chat, they suggested soaking the tip in warm water for 15 minutes, then to try twisting to open and even reversing directions a few times. After a few tries, this worked.
      Hope this helps anyone else who might have this problem.

      Today was out in a park, shooting coins with a friend. (Between us, got three forties wheats, 1940 Jefferson, a Mercury, and a silver ring) Beauty weather for December: high fifties, sunny. Nice day. In the middle of it all, whilst I was rooting in a hole, my TRX pinpointer started playing a song! I thought it was telling me to change the battery. No, it was playing a weird little ditty. Neither my friend or I could recognize the tune. Anyone have any light to shed on this? I found a YouTube video from 6 six years ago, but I'm not even sure it was the same song... I wish I had thought to record the song with my phone, but I admit I failed to think fast enough.   😞     Oh, White's Electronics, you shall be missed!

      Earlier people were looking for a TRX pinpointer. Centerville Electronics has a refurbished one on their used page for $95 with a 6 month warranty. Already have one or I would have jumped on it.
      Cheers
