Coils for Big Bud 1

Coils used on the Tracker IV, Quick Draw, etc. have not changed in many years and work at 6.59khz. If the connector fits, go ahead and try one.

In some cases there have been changes in BH searchcoil specifications over the years. First Texas has no reliable information on the pre-Texas BH products and therefore I cannot say what will or will not work on older BH products.
Specifications for White's coils and for BH coils are VERY different. The idea that similarity in machine operating frequency is what makes searchcoils compatible is commonly encountered on forums but is erroneous.
In the case of old (Oregon and Arizona) BH and Teknetics products, some customers have reported success adapting White's coils and some have reported success using or adapting current version BH coils. Evidently depends on what specific old product you're trying to get a searchcoil to run on, how good you are at wiring in a different connector if the connector currently in production doesn't mate with the oldie, and how willing you are to ignore deficiencies in operation.
If someone wants to play around with a current production BH searchcoil, the cheapest way to get into the game is with the 4 incher with the push-on plug. It's probably the lowest cost accessory searchcoil in the industry, been a while since I checked list price but I think it runs about $50. If an oldie works well with the 4 incher, it should work well with the current 8 and 10 inch concentrics and the 11 inch DD all of which are interchangeable.

Informative reply, Dave, as always! Another good way to grab a "spare" coil is to look on the big auction site or in the used/classified sections or even at yard or estate sales. You can pick up a second-hand machine with coil attached and have a "new to you" machine to play with besides the coil at the new price of just the coil alone. I've seen the 4" coil go for as low as $10. Don't overlook the 7-incher, either. They go almost as deep as the 8-inch, fit in a little tighter space and have a nice,crisp response.
The "standard" BH coil connector as found on a Tracker IV, etc., is called a DIN-5. It's used in many other applications, such as for microphones and the audio/electronics world in general. You can buy many variations of it with locking/screw collars and matching jacks, inline and panel mount, so it should be fairly easy to make up an adaptor if you can strip a wire and solder.
