Default Fisher F-Pulse / Teknetics Tek-Point Slow Start-Up Fix

I've been a big fan of the F-Pulse since I got it in a F75+ package. Being able to pinpoint exactly where a target is 4" down has made my park digs much easier, easier being I don't mind using the hand digger at all now in parks where previously I just considered a necessary evil.

But one thing held me back from permanently putting the Garrett Carrot away, and that was the painfully long start-up, anywhere from 3 to 4 seconds. Well, I ran across a fix on Dankowski's forum, and after running this calibration twice my F-Pulse now starts up instantly and works better than ever. I'm not sure why they don't put this in the manual, but they definitely should in the future. Here is a cut and paste for anyone else having the same issue:

If you quick-press the button to turn on, the LED code is bypassed, has no effect. What happens on power-up is some internal calibration stuff. It is critical during power-up that the PP is held away from metal, if you're waving it around and it sees metal (and it can see large metal from a fair distance) then this will extend the cal time.

The cal is supposed to be accelerated by a factory calibration that saves a very close starting point in memory. If you are still seeing a long power-up delay, you can re-cal your F-Tek and it should speed up. Here are the steps:

As you turn the PP on, you can continue holding the button to toggle the state of the LED. That is, if the LED is normally on and you want it off, continue holding the button on power-up and after about 1 second the LED will turn off. At the instant the LED turns off (or on), release the button and then immediately press the button 6 times in a row. The PP should beep on every button press. After the 6th press stop pressing the button and just hold the PP still, it is now doing a cal routine. This can take up to 10 seconds to complete so be patient. When it's done the PP will beep 2-3 times and the LED will start doing a weird dance. Turn it off, then turn it back on and see if it's faster to boot up.

Two things to keep in mind...

1. Keep the PP away from any metal during the cal procedure.
2. The cal procedure also executes a factory reset on all settings.

This tip works great.

I did it a few weeks ago and now with a quick press the F-Pulse boots a lot faster.
