Radio Shack Discovery 3, what is it?

I bought a property that had a radio shack discovery 3 left in the closet, I had to put on a new battery connector. I think it is a bounty hunter. If you know what it is could you let me know so I could find instructions? I am a newbie and bought a bounty hunter 505. Thought my wife could use the (if I can talk her into it) other. Thanks for any help!!!!
 
Thanks much, I had found that but being the lazy one, I was hoping to find some illustrated instructions for the original maker of this unit. It seems to be a pretty good unit.
 
Reading through the material on the Radio Shack website, it appears that this is the predecessor to the BH Land Star, which however is in the "muffler on a stick" configuration. The Land Star itself was major-rev'ed internally about 2004 but the externals remained the same.

I also suspect that the D3 is a direct descendant of one of the old Teknetics "Bud" products which was in a housing something like what you see in the photo, probably the same tooling. The "Buds" had a pretty good reputation.

The patent numbers on my D3 is:

U.S. Patent

4470015 - George Payne, Richard Hirschi for Teknetics

4677384- George Payne for Teknetics

4300097- John Turner for Techna Inc.

These are Teknetics original patents. Look them up here:

I usually just lurk and read on the forum but thought I would respond to this one. Pennyfinder, I have 2 D3's, one is tored up not sure what the problem is. The other one i just put 2 new 9v connectors on and it works good now. The one that works has the same patent no.s as yours. However on the one that is not working, there are no patent no.s, it just says made in the u.s.a.

Anyhow i do like them and it has the best/accurate target i.d. of any i have owned. The bounty hunter big bud 220 D, is similar as i had one of those also, but like the D3 better. It is good to read about some of the obscure or forgotton about detectors.

Hey there tbird, here is some more info from earlier posts on the D3:
http://www.findmall.com/read.php?18,299233,300123#msg-300123

Although similar to the Big Bud Series, the Big Bud Pros have an additional patent listed, in place of patent #4300097.
It was patent # 4128803. This is what differenciates the D3 from the Big Bud Pro SE.
Now what patents on the Big Bud Pro SED is what I don't know. :shrug:

On an air test on a US Dime, how many inches does your D3 do?

Just reading the earlier posts......12-14 inches on a quarter with the 7 inch coil ??? that is unreal. I will test mine with different coins and get back to you. You probably know this already , but bounty hunter coils will work on this detector also. I will test with the stock 7 inch.

Thanks for the info !

I was reading April '88 of the W&E Treasures and in it there was a test of the Big Bud Pro, it tested 10" on a copper penny with the 8" coil.
My D3 does 8" on the penny with a 7" coil.

Someone had told me if you change the coil plug, you can use the older Whites coils. Anybody have the skinny on this?

There was a coil cord adaptor(12") that allowed older Whites coils to work with Teknetics/Bounty Hunter units. It does require the older TEK/BH twist connector. Keith Wills of www.brokendetector.com might have a few left in stock. The Jimmy Sierra coils sure work nice with my Mark 1 and Mark III hipmounts. :clapping:
 
Yep, i bought one to use with my BH machines that accepts whites coils and another that would work on Whites machines to use bounty hunter coils. I actually used a 4 inch bounty hunter coil on a Whites 6000 di pro sl and it worked good. i bought them from Keith Wills about 5 or 6 years ago, and now i have been looking for them around the house for 3 months, don't know where i put them. they do a good job though.
Going to get to that air test on the Discovery 3 this weekend.

Thanks straker, good info! :beers:

Here is a pic of my Big Bud Pro SE which has a little more depth performance than my D3 plus it has the surface blanking feature.
The air tests on this machine rivals the magazine tests on the original Big Bud Pro, which was 11.75" on a penny in all-metal, a nickle was 12" am, a dime was 11.25,
quarter 13.25. This was using an 8" coil.
My D3 is close to this with the with the 7" coil.
