4900DL/Pro Plus, 4900DL/Max Differences
Posted by: PennyFinder

What is the differences between the 4900DL/Pro Plus introduced 1990 and the 4900DL/Max introduced 1995?
Both have black boxes and my 4900DL/Pro Plus I just snagged, has a signal balance knob like the DL/Max has.
Always wanted a Bigfoot coil for field sweeping so I found one for a good price and needed a detector to go with it.
I found a venerable little 4900 Pro series for it. Good in the heavy Pacific Northwest mineralization we have here.
Any reason Whites doesn't recommend the Bigfoot coil for the XL Pro? http://www.whiteselectronics.net/calif/accessories_loops_.htm#xl
You would think you would get some added depth and bad ground tolerance over the XLT.
Anyways, first post, how did I do?

If I remember right the difference Between the early production models of the DL Pro Plus and the newer DL Max was the addition of the signal balance and hot rock accept/reject controls. They may have added the signal balance to later production models of the Pro Plus though. Great detectors and I always have my eye out for a good DL Max for sale. They work great in our fickle Pacific Northwest soil. By the way you did good !

Yup, Crazyman this DL/Pro Plus has the hot rock accept knob and the signal balance knob.
Wonder how one of those multitone kit installed, would make this good little detector into a GREAT little detector.
It is the same basic circuitry as it's bigger brothers, the 5900Di Pro sl and the 6000Di Pro sl only lighter because there is no meter. My Classic III SL never felt out gunned without a meter. Sure is alot handier than my MXT, much like a Honda for city driving as opposed to a full size pick-up.
How about a nice Lithium Ion 6 volt battery pack to lighten the load even further.
Kinda makes me go hmmm? What an underrated detector.

From what I understand the Tone ID mod. won't work on a 4900. The mod. circuit is based on the VDI Meter circuit of the 5900/ 6000 series which the 4900 does not have.N/T

According to the catalogs and what was stated at the time, (now relying on aging memory) the 4900/D Pro Plus was in the blue box, the 4900/DL pro Plus was in the black, SL configuration. Both came with an 8" coil and DID NOT use the Blue max series of coils.

The 4900/DL Max came with an 8" coil, but WAS compatible with the Blue Max series of coils. The 4900/DL Pro Plus had GEB-Norm, GEB-Disc., TR-Disc. and GEB Max., while the 4900 DL Max had the GEB-SAT in place of GEB-Max. It was based on the revises circuitry being incorporated in the 5900 & 6000 Di Pro's, less the TID circuitry. It also had a Signal balance control. If you have a DL Pro Plus w/Signal balance, it might have been during a transition from one model to another and just got a different side decal or something. The older versions I didn't care for. The latter one worked OK.

Thanks for the reply Monte, your posts have always been the most informative and interesting reading with your willingness to share your long history of detecting. Kudos to you brother!
The GEB Sat is present on this DL/Pro Plus as well as a Blue Max 800 coil. Must be a transitional machine as you said, much like the XL Pro 6000/ XL Pro. They must not have all the decals made yet for full production or they had a lot of extra DL/Pro Plus decals to use up. Here's the little beastie for study at this link:

Ah right you are Adam, come to think of it it when I connected a digital voltmeter to the TID circuit of the analog meter on my Garrett Master Hunter 7 I had a 0-100 digital TID. This should work with the metered Whites 5900/6000 rigs as well.

Just received an email from the seller of the DL/Pro/DL/Max Whitenstein and he said the lower box was replaced with and nos. DL/Pro and the unit is really a DL/Max. Well that solves the mystery. Thanks to all.
Buy the way the seller is sending me the original bottom case and all the records from the Whites refurb. Nice fellow.

Hi Monte,
Why do you think Whiteselectronics.net doesn't recommend the Bigfoot coil for the XL Pro. You would think the added depth from the XL Pro would be welcome. Reading some of your earlier posts I know you are not a big fan of the Bigfoot coil, but what do you think? The 6.59khz Bigfoot was designed for the 4900/5900/6000/Quantums/Spectrums/XLT but not recommended for the XL Pro? Strange.

That's not the total 'official' White's site, but the site for White's of California and Jimmy 'Sierras' distributorship web site. It's showing Jimmy's "approved" search coils and not really what would come directly from White's in Sweet Home.

Note that he says the Bigfoot is showing up in Competition Hunts across the country and he refers to the "White's Pro" models.

"The Bigfoot is showing up in competition hunts across the country, even on plowed fields in England. It is designed for use on all White's Pro model detectors such as the 4900, 5900, 6000, Quantums, Spectrums and XLTs."

Note, also, that all the models shown are those that were offered before the 6000 Pro XL and renamed XL Pro were available. Personally, I chock that up to simply not updating a website for older, dated models, while they have been updated for the accessories for the more current models offered.

Yes, you're also correct that I am not overly excited about the Bigfoot coil. I prefer smaller-than-stock coils that let me work in and around brush and building rubble. Also, it should be noted that many (most?) clubs that host a 'competition hunt' enforce a rule that does NOT allow the use of the Bigfoot coil, or similar coil offerings. Personally, I'd let anyone use it because I can move faster and pinpoint better with a 6

Now I really want a XL Pro there Monte! Is there anyway we could petition Whites to manufacture a special run on this beauty? Judging by all the demand out there, we should be able to amass 100 orders at least. I've asked a dealer in California if he had one in stock and he said yup,couple of brand new ones the shelf but he is hoarding them! @#$%^&*!
OOPS! sorry guys, my teretz syndrome made my typing finger swear!
