Harbor Freight handheld

Well, got it Monday, took it out tuesday, worked fairly well, very loud. Have a friend who does electronic things. got it rewired, adjusted the secondary sens inside the unit, put a cell phone vibramotor in it, works awesome!

Perhaps your friend wouldn't mind doing a diagram of the way to hook up the vibra phone thing? I'm sure many would be interested. I have used the Harbor Freight tool for a year or so and found that if I have on head phones and working near a highway or busy street I can't hear it. Thanks. Monty

Been using mine for a year now with no problems and the same battery it came with.

I watched him do it. The way he mounted it was he stood the vibramotoro on end and placed it just below the screw that holds the coil on and the hot glued it in place. Soldered the wires that were going to the speaker to the motor, then put another glob of anchor glue over the bottom of it. Doesnt appear to interfear with the coil at all being where it is. Plus, if I ever need to open it again, you dont have to worry about pulling the wires off. I'll get my camera from home and post some pics of it. He did an awesome job of it. And it works like a champ with the secondary sens adjustment we made. Was able to find a 1/16th" wide by 1/8th" long sliver of metal in hard packed dirt. Wasnt actually doing detecting stuff, just put it near the ground to see if there was something there, and there was,

Here are the pics. Modified the outside of the case



As you can see, we removed the red switch completly and covered it up, put a normal toggle switch on top where the light use to be.

A little size prespective. its a tiny tiny motor but damn it sure makes the thing vibrate a lot!

Here's another trick for the HF pinpointer. You can add a bright blue LED to those same red and black leads for the speaker. It will only go on when it detects the target. That should work in noisy locations for you. It's amazing what you can get from a $16. pinpointer!

Nice mod. Harbor freight has some good deals. In my experience the stuff does not last long which is probably why its so cheap but for that price you can buy a bunch of them and still be ahead of the game vs. what you pay for other pinpointers.

I bought five when I first heard about them and caught them on sale. I gave three of them away to other MDers and kept 2. One of the two quit but the other one has worked for months. I'm sure the broken one just has a loose wire and I'll fix it some day. Monty

I have had mine for around 2 years and it's still working.
I like the sensitivity control, crank it up to where it
almost sounds off in the air and it will lead you to your
target, crank it down as you get closer. You can't beat
it for 15 bucks.
