Topic tags/keywords: metal detector centech cen-tech planer

and read the instruction book for my newly acquired
Cen-tech metal detector wand.

Not being one to gamble with my tools I would like to know any thing that I should be aware of concerning the detector. Is it reliable? Is there any thing I should know that you experienced users can give me a heads up on? I don’t want to ruin the blades on my DW734.

I don’t have specific knowledge of this one but cheap detectors such as are better than nothing but they can still miss things. The size and orientation of a nail, not to mention the depth, can make pieces of metal hard to detect. I suggest that you experiment with a 2×4 and drive some small nails and brads in at various angles and depths on one side and see if you can find them from the opposite face. This will give you an idea how reliable it will be. Keep this test piece around so that you can use it to test to make sure that it is working before you use it on something you really plan to run through your planer. Make sure that you scan both sides and along the edges of any board you intend to plane.

Thanks Nathan. One thing that puzzles me is that there is a button to turn down the sensitivity. Why would you want to do that?

I only use it to adjust for environmental changes, particularly temperature changes, as they are not temperature compensating.

For normal use, just set it at its most sensitive – hold it up in the air away from any metal, push the button and turn the sensitivity knob until the light/buzzer sounds, then back it off just until it stops and leave it there. For shop use, that should be just fine any you shouldn’t need to touch it again – although you may want to repeat the procedure every now and then just to make sure.

I use one for, in addition to finding metal in wood, as a pin-pointer when out in the field in conjunction with my large detector. If i lay it down in direct sunlight so it heats up, it will throw that setting off – and it will sound off as soon as I hit the button even with no metal present – so the sensitivity needs to be adjusted. Easy fix for that is I just keep it in a pocket out of direct sunlight :)

Cheers,
Brad

PS: The one I have is the little handheld one, not the wand – although I imagine they are both similar as to setting the sensitivity. Not sure which one you got.

Adjustment is also for battery life compensation.

Thanks Brad for that information, now I know better how to prepare learning to use it properly. I saw the one you have at HF but decided to go with the wand although it is more expensive by almost double and I had a 20% off coupon.

It has a nice carry bag to store it in along with a strap so I can keep my ear bud in there also. Have to use that because when it sounds off it scares wify’s cats and they take off for distant places. :) larry

Papadan, I guess I didn’t think about the idea of it using more battery life depending on sensitivity. I’ll watch that as I go along. larry

On occasion, if the sensitivity is too high, it may pick up two nails in close proximity as one. After removing one always check again.

I’m not going to be much help with your metal detector. The ones I’ve used have been OK.

I have done a few things with recycled lumber. After I take the wand to it, I always go back over it with magnets (Lee Valley super ones) and I always find more iron.

-- nice recovery, They should pay extra for that mistake, Eric E.

DD that is good advice, I’ll do it. Thanks larry

Eric Amazing! I will do a double check and then use my computer drive magnets. Thanks for the heads up.
Thanks larry
