Another Great FREE App For Your Smartphone!

I like this app too. I wish it had a inclimometer to measure pitch and roll.

Are you measuring pitch and roll in a plane or a boat?

Thanks for the pointer. A very handy app.

Hey thanks for the info.

Thanks for the link. This is the best GPS I have used yet. Lots of good info and good navigation options.

In a truck/car.

I've been using Ulysse Gizmos for some of this (which DOES include an inclinometer), but this is nice...VERY nice

thanks, downloaded it to my phone, will play around with it

My daughter needed to find something in her yard so she looked and there was a free app metal detector.
It worked and she found what she was looking for.

I couldn't beleive that was possiable!!

I love checking out new apps. This one looks good..Thanks

Appears to be Android only, pity, it looks like a useful little app to play with.

I am astonished ... just downloaded such app and it really detects metal objects ... well at least at close distance, but it really does it ... I feel like I lived in one of the SciFi movies where people have all those fancy gizmos telling them everything ...

When I asked my son how it worked he said that metal det. are very simple and that this must use the coil of wire in the speaker.

I thought my daughter was pulling my leg when she told me about it!!

My daughter said she must have look silly holding her cell phone at ground level when looking for the object. It does have to be close.

I did NOT know a metal detector app existed (I've since searched the Android Market and grabbed it) but I can see very easily how it'd be possible.

At least on many Android phones (and quite possibly iPhones too), there are built in sensors besides the obvious radio sensors and the temp sensors (the latter to keep the CPU from overheating). Quite a few Android phones have built in magnetometers (the G2 being among them), many also having positional sensors as well.

(My two pence--magnetometers were probably included in part for position sensing and in part for use as a magnetic compass.)

There are a surprising number of apps that let you play with this. There's magnetic-compass apps out the wazoo (Orienteer, Ulysse Gizmos, etc.) and some that just straight out measure magnetic field (Tricorder, which is darn cool even for the Trekker aspect, does use the magnetometer so you can measure magnetic field strength--and yes, it does increase around ferromagnetic objects).

Seeing as a metal detector is nothing more or less than a magnetometer with a coil close to the ground, I can see how this could work. :3 (And yes, you could very well use the speaker wire for this...so your kid's comment is more accurate than you realise!)

Yeah, I love smartphones because of the countless useful apps which are developed every single day. If you can imagine it there is probably an app for it.

For example, there's an app to measure your heart rate using the phone's camera! https://market.android.com/details?id=si.modula.android.inst...

Crazy stuff, LOL!!!

I too am astonished!!!! I thought my legs were being pulled, LOL!!!!
