So after hunting at a Park my friend Greg and I went to a beach, first time with the Alter. Right away I was baffled by the amount of chatter. Changing freqs made minimal difference and I did find a couple of items at 4". The beach was fine sand with a very rock water line- low tide, loaded with iron trash. I realized the sensitivity was at 75, after lowering to 50 the chatter was mostly gone. I am looking for tips for beach settings from you experienced folks.
Finding hidden or lost items is my favorite hobby during free-time. I use bounty hunter for detecting. Last week, when I was cleaning the basement, I found a mining instrument, an overhauser magnetometer. My brother might have left it there. He is an Archaeologist. When I read about it, I understood that, it can be used for detecting gold mineral. Does anyone here heard of finding treasures of stuffs with a magnetometer?
By nature I like to improve things for the better. I took a real liking to the Bliss V5 but, it needed something.
Decided to replace the scratchy GB pots. Fine adjust pot is bad between 3 and 7, worn carbon wiper inside. Replacing with RV6 precision mini pots.
I was going to use a 10 turn for Coarse pot. That idea was shelved as they don't make them in the 500R ohm range. Both pots will be single turn.
What I clued in on awhile back and then saw some one mention on a forum regarding the Gain pot. For the most part you don't need to set it higher than 2. And would like the 0-2 or 3 range spread out further. That was my thought as well. So I will be replacing the linear pot with an audio taper pot. It spreads out the range over half the pot rotation, super fine tunes the lower numbers. I will be measuring out the spread between the linear and audio pots to see the exact spread.
The V5 is now open and taken apart. Will have it ready this weekend.
Will also see if there are any other improvements that can be made....
I did make a very positive s-handle mod. The angle of the handle was a bit too steep, it would tend to bother my bad wrist after awhile. Not enough so I could not keep detecting.
The most comfortable s-handle I found was the White's Space Saver (What they call it). Which I have used for all my Pi builds. With a bit of muscle power, bent the Blisstool s-handle to match. This little mod, that didn't cost a penny made a huge difference. Search coil 7x9", balances just about perfect, and now has a wonderful feel about it.
Made the Coarse and Fine GB pot changes to precision pots. Big difference. The usual cheap carbon pots used like most detectors had poor resolution as you turn the control. I watched on the voltmeter, when you rotate the Blisstool pot, a slight movement jumps the settings about 10 points, you you will never get precise GB setting. That's why trying to GB is very touchy. With the new precision pots a slight rotational movement of 1 point increase in settings can be made. This should definitely help out manually ground balancing, getting a spot on GB.
Second change was the Gain control. I switched the Blisstool cheap pot with another basic carbon Alpha brand pot (Tesoro, etc. used them). Instead of replacing it with an identical "Linear' taper pot, it was replaced with an "Audio" taper pot. Since most will run around 2 or 3 on the dial. The rest of the rotation is wasteful. With the new pot orig Gain setting from 0-3 is now spread across 0-6. You can now dial in more precise Gain where you need it. Then ramps up closer to the orig. pot. Also shows a bit more added Gain at 10(max).
Thinking some of the other controls might benefit from switching to a precision pot or an Audio Taper pot. For those that have a Bliss in the closet gathering dust, some easy modes might just make the Bliss owner a more happy user.
Hoping to get out with the V5 Sunday afternoon for a test run

I could not find a t-shirt I liked at the Mesa Gold Show so just had to have these!
