thanks i'll give it a try
Here' pics of my old Red Baron...
I'd like to have a manual, or even a copy of someone's, if possible.
Did not see anything posted on the BH site, but did not ASK yet...
I've used it with 9v batts, but know I should not... what SHOULD it have?
REALLY need to get a new bicycle grip for it. Sure looks dumb with the tape on it.

Hi folks,
I too have recently purchased an old Bounty Hunter 840 Auto ($10 NZ!) detector minus a manual. I came across this thread while searching for information about it and being fairly new to the game was wondering if someone could email me a copy of the manual?
Regards
Sean

For manuals for your metal detectors, e-mail vcastro@frsttx.com . Veronica will send you a copied manual for the metal detector you need one for plus a brochure of the current line-up of the Bounty Hunter metal detectors. If I recall, it only took about a week to receive it. (btw, it was for the VLF/TR 840 Automatic) Mine has a 6" coil and the 3-9V battery set-up.

BOUNTY HUNTER 800 & 840
VLF TR Discriminator
OPERATING INSTRUCTIONS
Precision Engineered
INTRODUCTION to the 800, 840 Discriminators
The 800 (840) is a Very Low Frequency discriminating metal detector. utilizing the inductively balanced Transmit/Receive (TR) technique to provide excellent stability and sensitivity in an all-purpose instrument. In the Normal mode, not only are all metals detected, but ground mineralization can be rejected to allow operation in all types of soil conditions.
In the "Discriminating" mode the 800 (840) is an ideal detector for the serious coinshooter, allowing the operator to control the amount of rejection of unwanted "junk" targets. Rather than a good/bad indication, the 800 (840) unwanted targets, yielding no audio tone as the coil parses.
NOTE: Do NOT use pliers or wrench to tighten knurled collar.
CAUTlON: Avoid losing the compression ring during unpacking or assembly.
NOTE: Approximately 90% of the problems from metal detectors are caused by weak, dead, or improperly connected batteries. If the unit does not come on, or comes on but has weak volume, will not tune properly, has erratic operation, or drifts - CHECK THE BATTERIES! When replacing the batteries, make sure fresh batteries are purchased. Many units are received at the factory for repair because bad batteries were replaced by "new" batteries with expired shelf life.
BATTERY REPLACEMENT
The 800 (840) is equipped with 9-volt transistor radio batteries (Eveready R216 or equivalent).
Access to the batteries is gained by pulling out on the nylon snaplok fastener on the battery cover on the rear of the unit and removing the cover.
A battery lead connector snaps to the respective battery terminals. The ~'8" battery powers part of the circuitry and the "A" battery powers the remaining circuitry, plus the audio output.
Batteries should last from 15-30 hours of use, depending on the make and freshness of the batteries and the length of hunt periods. Using headphones will extend the battery life of the "A" battery
When replacing the battery cover, insert the cover tabs in the slots, close the cover inserting the snaplok fastener through the round hole and press the fastener until it snaps into the locked position.
Caution: When the detector is to be stored for a month or more, it is a good practice to remove the batteries from the unit as weak batteries can vent and leak. This leakage is corrosive and can do serious damage to the unit.
Mineralized Soil: If the ground becomes highly mineralized, it is recommended that the searching be done in NORMAL until a target is detected; then, if desired, the unit can be switched to Discriminate to verify before digging. At a sacrifice in sensitivity, it is possible to search in the Discriminate mode in some mineralized areas by detuning the detector slightly. By operating just below the threshold, the false target indications due to mineralization can be eliminated.
NOTE: The electronic circuitry of this detector was designed to provide excellent stability but, as with any detector, it is a good idea to check the control settings occasionally to maintain the best sensitivity and discrimination level.

Anyone know what frequency machine is the VLF/tr 840?
It has some nice features, it would be nice if it were 10 to 15 KHz, great for coins and jewelry.

Wow.....the 840 was my first detector. Got it back in the late seventies/early eighties (can't remember for sure) as a christmas present. Would be real cool if one of you guy's could post a picture of yours here. Would love to see one, for old time's sake?

Thanks Fisherfinder but for some reason, I am not able to see them? If I quote you in a reply, I can see the links to the pics. but that is it. I recently switched from XP professional to Vista business. Might have something to do with it. Sure wish I was more computer literate. HH-CC

Now I see them! Thanks a lot Fisherfinder. Brings back a lot of good memories.
The one bad memory was when I had to pawn the 840 and my second detector, a fisher LF 990-D to buy diapers......lol! It was many years afterwards when I finally got another detector. If any of you guy's got your 840 from a pawn shop in Panama City, Florida, it just might have been mine. HH-CC
