From https://www.detectorprospector.com/forums/topic/5683-fisher-f-pulse-versus-garrett-carrot/?do=findComment&comment=69859 by First Texas engineer Carl Moreland:

“There are 2 software versions, R1 & R2. R1 had a lock-up problem if you turn the unit on while overloaded. R2 fixed that problem, and in the process I added a few new features. Therefore, you need to figure out which version you have as I moved the factory reset from 3 clicks to 2 clicks, should you need that feature. The easy way to tell what version you have is to turn the thing on while a coin is right against the tip; if it locks up, that's R1; if you hear a beep-boop-beep-boop-beep-boop overload jingle, that's R2.

In R2 I slightly extended the default time-out from 2s to 3s. I also added a Turbo-On mode which bypasses the auto-cal procedure and shortens the power-on time to maybe 1/4 seconds. There is a separate Turbo-Off mode which reverses the "off" and "retune" functionality; a quick-press powers down, while a press-hold retunes. If you use both Turbo-On and Turbo-Off, then the F-Tek powers up & down incredibly fast.”

F-Pulse Detailed Instructions Revision 1

F-Pulse Detailed Instructions Revision 2

Only version 2 of the F-Pulse features Turbo Mode. From the Revision 2 instuctions above:

Advanced Features

All advanced features are accessed in the following way:

1. From OFF state, press/hold the button; there is an immediate single audio chirp.
2. After 1⁄2 second, the state of the LED toggles (off-to-on or on-to-off).
3. As soon as the LED flashes immediately release the button, then quick-press the button N times in a row. Each press will be indicated by a short beep. The number of presses “N” determines the feature selected, described below. Further steps are also listed.

N=2: Restore Factory Defaults

This procedure restores all settings to factory defaults:

Response = Beep+Vibe
Sensitivity = 2
Frequency offset = 1
LED = On, 70% TurboOn/TurboOff disabled

4. After 1⁄2 second the LED will begin weirdly flashing, indicating success.
5. Quick-press the button to operate, or press/hold to power down.

N=3: Turbo-On Mode

This procedure toggles the Turbo-On mode. Normally on turn-on the PP executes a calibration routine that optimizes the sensitivity. This can take anywhere from 1⁄2 to 1 second. Turbo-On bypasses the calibration and immediately goes to operation. While much faster, the downside is a slight reduction in sensitivity, and over time hardware “aging” may require occasional calibration (see below). Note: TurboOn also shortens the turn-on response.

4. A short beep indicates completion.
5. Quick-press the button to operate, or press/hold to power down.

N=4: Turbo-Off Mode

This procedure toggles the Turbo-Off mode. Normally to turn off the PP you press/hold the button for about 1⁄2 second, then release. In Turbo-Off mode, only a quick-press of the button is required to turn off. Note: Retune is now based on a press/hold of 1⁄2 second, indicated by a brief chirp. Note: TurboOff also shortens the turn-off response.

4. A short beep indicates completion.
5. Quick-press the button to operate, or press/hold to power down.

N=5: Calibration

This procedure recalibrates the internal DAC which primarily affects turn-on speed in Normal mode, but in TurboOn mode can also optimize sensitivity.

CRITICAL: Keep the PP away from any metal during the cal procedure (including watch/rings on hand).

4. Calibration can take up to 10 seconds; when done, unit will beep 2-3 times.
5. The LED will begin weirdly flashing, indicating success.
6. Press/hold to power down.

N=6: Calibration & Master Reset

This procedure recalibrates the internal DAC which primarily affects turn-on speed. It also executes a factory reset on all settings.

CRITICAL: Keep the PP away from any metal during the cal procedure (including watch/rings on hand).

4. Calibration can take up to 10 seconds; when done, unit will beep 2-3 times.
5. The LED will begin weirdly flashing, indicating success.
6. Press/hold to power down.
