A handheld garden tool which has a line trimmer ("strimmer") with a metal detection search coil integrated into the cutting head.
The user wears headphones, which convey the indicator tone from the detector electronics, and exclude the annoying whine of the motor.
Handy for those who want to add the prospect of financial gain to boring vegetation management, and in heavily mined areas*.
If you get a positive tone, the ground is already cleared, ready to be investigated further.
That is all.

Indeed, such devices are of little benefit retrospectively.-- 8th of 7, Sep 14 2020 Handy bomb defuser kit available at extra cost?-- whatrock, Sep 15 2020 Have you run it over your head yet in its mental detector mode? [+]-- xenzag, Sep 15 2020 Wouldn't another search parameter other than just eddy looking, such as divining line, be more financially lucrative.-- wjt, Sep 15 2020 I wonder if the motor would interfere with the metal detector.-- benbradley, Sep 15 2020 Not if the motor is in the handle, and drives the head through a flexible shaft, using ceramic bearings and polymer components.-- 8th of 7, Sep 15 2020 Well of course.-- whatrock, Sep 15 2020 Yes, [what], that's the sort of stupid question that gets asked in a mixed-ability class.-- 8th of 7, Sep 15 2020 //How about a detector in the heel of a shoe?//
[el linko]-- 2 fries shy of a happy meal, Sep 16 2020 //motor would interfere with the metal detector.//
Good metal detectors have settings to reject iron, since it's common and either worthless or rapidly oxidizing into worthlessness. Also, since a bearing or whatnot would be stationary relative to the coil, it could be baselined out.

You forgot that the strimmed grass will provide a handy visual reference for the areas already searched, plus, if you're going to ask a farmer for access to their field, they might be more inclined to agree if you're mowing it at the same time. Less so if it's a big field of barley or something.-- bs0u0155, Sep 16 2020 And the boss says "Mark it and get on with the job. You can dig in your own time"-- wjt, Sep 17 2020 The DeLuxe version has a paint sprayer nozzle in the centre of the spinner; pull the trigger, mark the spot, move on.-- 8th of 7, Sep 17 2020 You missed out the flame-thrower (see link), which is odd, for you.-- hippo, Sep 17 2020 It's in development - just temporarily suspended for reconsideration. Work will resume when the smoke clears and the debris are cool enough to examine.-- 8th of 7, Sep 17 2020 //DeLuxe version has a paint sprayer nozzle//
This shouldn't be in the visible spectrum, or metal detecting will become a little too accessible.-- bs0u0155, Sep 17 2020 //[el linko]//
Gotta hand it to you 8th, that was even kind enough to mention how fun it would be for kids.
Totally spoiled my joke.-- reensure, Sep 17 2020 I love this. I missed this. I'm forever sorry, 8th. I shall never be so lacking in my bunning duties ever again.-- blissmiss, Sep 17 2020 //I love this// - <recommendations algorithm>"Customers who liked this idea also liked the nearly identical idea posted 17 years ago (see link)"</ra>-- hippo, Sep 18 2020 Due to the poor phrasing of your proposal, that idea didn't come up on our preliminary searches.-- 8th of 7, Sep 18 2020 So 8th is evolving to think like hippo from 17 years ago? <stunned silence> There's hope...-- RayfordSteele, Sep 18 2020 Oh, that's scary, [RayfordSteele]. Think of what might come. (Sorry, [hippo], I missed the link as well as the idea. Shoot. Good one.)-- blissmiss, Sep 18 2020 Even 8th occasionally comes up with a nugget of an idea.-- AusCan531, Sep 19 2020 Actually, yes, the idea is to come up with nuggets, or failing that, coins or jewelry.
// There's hope //
There's no hope. There's no safety, in numbers or anything else. There is no alternative. We will add your biological and technological distinctiveness to our own. Your life as you have known it is over. You will be Assimilated. Resistance is Futile.-- 8th of 7, Sep 19 2020 Daleks versus the Borg! The Daleks would have a field day exterminating the feeble Borg like cockroaches. It would be like spring cleaning.-- xenzag, Sep 19 2020 //So 8th is evolving to think like hippo from 17 years ago?//Scary indeed. The only other possible explanation is that I am converging on 8th’s thinking, while also travelling backwards in time-- hippo, Sep 19 2020 How foolish- time travel is completely impossible.

// The Daleks would have a field day //
You wish. Bring'em on... those sink-plunger waving tin-dustbin losers don't frighten us. All across space and time, they consistently get defeated by one rogue Time Lord and a random bunch of misfit helpers (Except for Brigadier Lethbridge-Stuart, who was a Top Bloke), often by something as simple as a floppy hat over the eye-stalk...
Besides, there's always the infallible defence of Hiding Behind The Sofa...-- 8th of 7, Sep 20 2020 //You will be Assimilated. Resistance is Futile.//
