The great thing about these changes is they cost very little and improve the performance enough for one last hurrah before the next generation of machines comes out.... if they were to come out. Maybe we will just re-release all of the classics! 16 minutes ago, Geotech said: But the reality is, that platform has pretty much reached its limit, which is why I was spending all my efforts developing a whole new platform. Unfortunately, White's made some choices that killed the whole thing. I have heard a lot about you in my short time here. You are a smart dude, and I would love to shake hands with ya some day. Next time you're in the valley let me know. As far as that platform I have no idea what you're talking about... Maybe it got boxed up and forgotten. Going forward our detectors will be bulkier, heavier, shallower, and have a shorter battery life than any other machine. Here is a picture of the next generation of machines from White's, it runs on forty 9v batteries and hits a nickel at 2 inches--- Link to comment Share on other sites More sharing options...

Tested with 4 18650's.... Interesting results at 16+ volts fully charged. Eight cells is unnecessary (and too heavy). 1 Link to comment Share on other sites More sharing options...

The best quality 18650's at 3400 mah will last about 5 hours which is not great, if 2400 mah batteries are used, as in the Pro, 3 hours max can be expected. One of the main drawbacks of the SL is the battery life and here you are again talking of an inadequate capacity battery. Give people what they want a battery that lasts a bit longer.

HardPack Posted December 9, 2016 Share Posted December 9, 2016 I just asked an uninformed question over on the "Impact of the New Nokta Three Frequency" post. As opposed to a multi-frequency metal detector, has there ever then a varible frequency MD with the varible adjustment on the control box? Link to comment Share on other sites More sharing options...
Geotech Posted December 9, 2016 Share Posted December 9, 2016 Tom, I'm in the valley every month, I live in Junction City. I even do field testing up Quartzville Creek, so I drive right by White's on the way. Next time I'm out that way I'll give you a yell. 1 Link to comment Share on other sites More sharing options...

Quartzville is my second favorite place, first is Josephine County serpentine contact zone. My mom's side is from JC, used to spend a lot of time on River Rd, at the JC pond, and haircuts at the old barber shop in town. Link to comment Share on other sites More sharing options...
HardPack Posted December 9, 2016 Share Posted December 9, 2016 Tboykin & Geotech, Over on the "Impact of the New Nokta Three Frequency" post, the Turks are putting on a feed for your "market shares". Gossip is the door prize is an proto-type varible frequency MD with a bunch coils in the 3 to 56 Khz range. Link to comment Share on other sites More sharing options...

By increasing the Volts in the SL, I'm curious as to what the interesting results are? Also, by increasing the volts, how does it compare to the TDI Pro?

We are the closest manufacturer to your neck of the woods and I hope to see you out there when I head down to NV next year! Initial test with a 14.8 volt battery (overcharged to 16+) showed the TDI SL within an inch of the PRO on nickel and larger-sized targets and neck and neck on smaller targets. This was with the stock 12" coil and also the smaller 7.5" DF. Wide open on both machines, GB off, delay of 10usec. But the SL was a lot smoother at full throttle. You can try it yourself for proof. I need to test it with more aftermarket coils like the MJD and Coiltek, but I would guess that results will be similar. You can make your own battery pack with a set of 4 18650's and some clever wiring but we hope to have a proper version soon. Such a simple change, and the bonus is it will fit all of our other machines that use that style of battery! 6 Link to comment Share on other sites More sharing options...
