on the F11, 22, and 44, and what msrp might be?

The F22 is $229 and the F44 is $349. Those are MAP prices. Like the Eurotek Pro, the prices are MAP (minimum advertised price). This from Anna K at FTP.

Good info. So my guess is they can be had for around $199 and $299. Pretty good deal for all the features. And I'm a big believer in FT products. The F19 I just got is smokin'.

You know those cheap throw away cameras with a flash..they can be turned into a tazer because they have a capacitor and they use just one 1.5 volt watch battery so you can get a lot of juice from a small battery or amount of batteries...however the demand to perform the same as say a 9 volt is going to drain quicker I would think.
Kind of confusing since the F2,4,5 use 2 9volts which is 18 volts but Garrett uses 4 AAs 6 volts and both run the same amount if time.
I'd love to speak to a metal detector engineer and pick their brain on how this works.
Carl-NC;2343828 said:And I'd love to have my brain picked.
Detectors with large battery packs typically have regulators to create a lower but stable voltage to run the circuitry. In the old days these were "linear" regulators and could only create a lower voltage.
Today we have "switching" regulators which can step-down or step-up the battery voltage to create whatever circuit voltage we'd like. Much like an AC transformer. We could run a metal detector off a single AA battery if we like, and still have the circuit running on 10 volts or whatever.
The trade-off is battery life. 2 AA batteries boosted to 6 volts runs half as long (actually a little less) as 4 AA batteries. However, it turns out that 2 AA batteries have a little more than energy (3V * 2000mAhr) than a single 9 volt battery (9V * 550mAhr). I designed the power circuitry for the White's TRX which can accept either 2-AA or 1-9V battery automagically, it will run a tad longer on 2-AA.
The F22/44 uses 2-AA boosted to a higher voltage (I don't recall what, as I didn't design it) and has a good balance between depth & battery life. We chose 2-AA to make weather proofing easier and to keep the unit as light as possible. And, yes, you can even have a backlight with 2-AA.
On the water-weather-proofing issue, these units are weather proof. They have a standard 1/4" headphone jack with a rubber plug, so if the jack is plugged it's possible you can dunk the unit and it'll be fine. But if headphones are plugged in, submerging it will cause a leak through the jack. The intent is to have a unit you can take in the pouring-down rain with no worries and no ziploc. It is not for wading shoulder-deep in the water.

Hightone said:I would agree. If water is your main choice in a detector, the F44 probably isn't the first choice. It is a land detector that can get wet, not a water machine that hunts land.
Cal_Cobra said:I see them up for preorder at Kellyco. The stock coil on the F44 is an 11" but apparently not a DD? Kco offers an upgrade package, but all it really does is give you coupons for half off the 11" DD or backpack for $50
PS - I'm considering getting the F44 for my wife, she needs a light and easy to use machine, and it's a great excuse for me to test it out
