  1. Just as a sidenote: On my Equinox the pod is attached to the shaft with stainless screws and the pod itself is equipped with brass inserts. I haven't seen any visable corrosion there, yet. On the other hand, the nickel plating of the headphone connector doesn't like saltwater all that much. I once didn't rinse it of and it got green quite quick.
  2. I kept away from those areas with the 11" of course πŸ˜‰ It's not like the whole beach was trashy - more like patches with exposed rocks, where all the stuff got caught. Tons of tent stakes etc.., but definitely good stuff, too. You "just" have to listen and go slow 😁 I'll take the small coil with me and look out, if there are still some patches. The weather is subpar atm. No hunting for 3 weeks I guess.
  3. Awesome! I always wanted to give the 9" a run on the hightly trash pulluted beach areas after the big storm last year, but I always ended up using the 11" in fear of missing the deep stuff. Now everything is sanded back in and I kind of regret I didn't try πŸ™„
  4. + EMI sources can potentially emit harmonics, too - making it even more difficult to handle in MF mode. If you refer to my video - yes, sure. But I'm still surprised, how good this simple setup actually works. The TX frequencies have a very low bandwidth by the way - I turned on smoothing to make them more visible on video. Without smoothing, there are just thin lines.
  5. Diving mode uses a lot more low frequency energy - just saw that, when I fiddled around with my microphone frequency tests yesterday, while scrolling through the programs.
  6. Some quick none-scientific testing using a simple dynamic microphone with an audio interface at 192kHz. What you see on the Laptop is the frequency range from 2-50kHz. Funny how some programs use the exact same TX frequencies and intensity, so there's definitely something going on at the RX side. You can also see, Freq. Shift in MF mode shifts all "masters" simultaneously.
  7. https://youtube.com/shorts/iD9JgAyx67E?si=PCOYykcfskAKu1iA Quick test with microphone on a mixing console - it really works quite good! Have to redo it with an sound interface and proper software. Sounds like a sine-tone πŸ˜…
  8. I don't know, if FMF shifts the frequencies excactly like Mono, but over all "masters" simultaneously - that has to be checked with an oscilloscope - don't have one atm. Perhaps it works with a microphone and audio analyser, too? πŸ€” But I think now I get what you mean.. the Mono "masters" do not match the Max Freq. Settings in FMF. Aka Mono "masters" are 5 – 7.5 – 13 – 17.6 – 25 – 32 – 40.5 kHz - but FMF Max Settings are 14, 24, 40kHz.
  9. Hm, from the pictures it looks like gold. Maybe soldered / repaired. Silver plated or junker would have had an higher ID imho. Nice ring nevertheless!
  10. As Chase quoted from the manual, I think Shift 3 represents the selected "master" frequency. 32kHz Shift 3 = 32kHz, Shift 0 = 29,41 and Shift 6 = 35,32. 40,5kHz Shift 3 = 40,5kHz, Shift 0 = 36,36kHz, Shift 6 = 45,45kHz and so on... As far as I remember, some russians analyzed the frequency spectrum with an oscilloscope somewhere on youtube.
  11. I agree - Location is key for sure.. But sometimes you have to take what you got, I guess. My beaches are located around a big bay. Very few hotels, not big either. No tides - if you're lucky, you have a big storm in wintertime, that takes away some sand on some beaches. This has been the case in October and that's why I found so many old coins. Actually I found as many old coins in 3 months, as I did previously in ~4 years! The pulltabs come in at a very broad range on the D2. Many of our coins happen sit exactly in that range.. so you have to bite the bullet - no cash without trash πŸ™„ For me thatβ€˜s ok. Itβ€˜s not all about the money and gold - free your mind after having a hard day at work ☺️
  12. I attribute that to my lack of language knowledge 😬 We call it "bridge" over here. Found in the water - probably one of my top rare finds, ever.
  13. We had so much rain and snow the last couple weeks, the fields look like a seascape πŸ™„
