No one? :ph34r:

On power-up, the micro calibrates the RX circuit and sets up the threshold levels. It's the calibration that causes the delay, and to help speed this up a "starting point" is saved in memory from a "factory calibration." This is done at Sens=2 but is still pretty close for the other 2 levels. It's very possible that Sens=1 can be faster, but it also might only be randomly true. That is, YMMV.

Some DIY cheapo protection tip:

D50BDFD7-152A-459A-9840-D32A8E654D3C_zps

This has been done with 1" heat shrink tubing (no glue inside).

I'll try 30mm next time, didn't have it in house.

With tip coated, the f-pulse loses sensitivity (lvl 3 sens) to micro jewelry and less than a gram of gold.

How did you coat the tip?  With Sinclair's heat shrink tubing or one of the goops?  For a given gain setting only two things will affect the sensitivity:  metal and distance.  One nice thing about the heat shrink is that it is thin enough not to affect distance much.  The goop/plastic-dip methods are more variable and thus if put on thick will increase the closest distance, potentially significantly.

I haven’t coated my pin pointer yet, looks like a great idea to keep it from falsing over time and hard use. If you can get your hands on a small gold earring post, Test it’s size and composition to pin pointer to see how if it senses before and after tip being covered.

with my unscientific testing, I can tell you my f-pulse has a hard time sensing smaller sized jewelry such as earrings.

I am not going to do anything to protect mine. The line below “Constructed from special abrasion resistant materials (won’t wear through like other pinpointers)” is good enough for me!fisher-f-pulse-metal-detecting-pinpointer.jpg

Works great so far - it found what the equinox found

Only had a problem once or twice with very small bits of aluminium foil.

Anyone else thinks the holster is too stiff?

Hi Sinclair,

I like that the holster is stiff, I just wish the Velcro straps were stiffer too. 

I love how sensitive that pointer is.

Yep, it wiggles on my hunting belt like crazy... That's why I’ve cable strapped it  down:

Holds up fine so far

      A Quick Look at The Nokta / Makro Pulse Dive
      I was fortunate enough to field test a prototype of this amazing device and was immediately impressed by the Pulse Dive’s rugged, professional feel.  The solid “heft” of the device made all other pinpointers I’ve tried feel like flimsy toys.  It’s also a great, practical concept—a waterproof diving detector with a deep 5.5” (14 cm.) coil for that converts in a second to a regular pinpointer.  The Pulse Dive features 5 levels of Sensitivity adjustment, selectable vibration, light and tone alert and can be paired with your headphones via a built-in wireless module.   The production model features yellow detail for easy visibility underwater and comes in a sturdy case.  The Pulse Dive kit includes covers for both coils, holster, lanyard, spare gaskets, charge cord and manual.  There's also a second, louder endcap for land use.  This is an extremely well-thought-out device—great not only as a deep, full featured standard pinpointer  but also for quick area searches of  dwellings, stone walls, enclosed spaces--and even as a security wand.   My tests showed the Pulse Dive to have great sensitivity to small gold—even chains.  It also had nice depth for coin hunting on land.  Picture shows a ’32 cent and '38 nickel—my first two finds pinpointed with the Pulse Dive.   A great addition to any serious inland or shoreline treasure hunter’s kit.

      My Profind 35 seems to sound off on nothing and seems to be getting worse. 
      If I turn it on away from anything facing upward it will sound off if I turn it facing down. If I turn it on facing down it seems to be ok but will start sounding off sometimes sideways. I have cut the sensitivity to halfway but that makes no difference. I have a fresh 9v in it.
      Has anyone else run into this?
      (note it is a replacement unit, previous unit the speaker died but would run pretty stable)

      If you've read some of my posts, you know I hate 9V batteries. I finally finished a working prototype of a 9V voltage booster so I can use a rechargeable LiPo in my Pro-Find 35. Here are a few pics:
       

       
      Based on indoor testing, the performance exceeds the stock 9V battery. If you want to learn more, check out my blog post:

      I was hoping to use loose AAA cells for this, but it would require permanent modification of the end cap and I'm not ready to do that yet.

      I'm considering the Minelab Pro-Find 15 and 35. It seems like the most important difference on a functional level is that the 15 has fixed sensitivity.

      To any of you Pro-Find users out there, is the adjustable sensitivity on the 35 important? If not, why not?

      Also, is the entire propointer a solid piece of plastic or is there a joint/seem where the black tip meets the yellow housing?
