AI Thread Summary
A user is seeking a small tracking device for dogs that can operate over a range of 0.5 miles or more, ideally the size of a watch battery or smaller. Concerns are raised about the limited signal range in hilly or wooded terrains, suggesting that existing wildlife tracking devices may be a viable option. GPS recording trackers are mentioned for post-retrieval mapping, but they do not assist in real-time tracking. Various links to wildlife tracking systems are shared, highlighting the importance of line-of-sight for effective signal transmission. The discussion concludes with a desire for a real-time tracking solution that fits within a compact size, similar to that of a pencil.

Does anyone know of a very small tracking device or tag that can be tracked .5 mile or more and the size of watch battery or smaller. I looking for such a device for dog tracking.

That sounds pretty small to have much range. Especially if the dog can be in the woods or over a hill, it will be pretty hard to get much signal out to a receiver. Your best bet might be to look at the existing animal tracking devices that are used by the Fish and Game folks for wildlife tracking.

I googled wildlife tracking systems, and got lots of good hits. Here's the hit list:

Interesting, if you are just interested in where the dog has been, you can use a GPS recording tracker, and upload the information after the dog comes back. That's no help if you're trying to find the dog, of course.

Hmmm, one of the first hits on the list is for a UK company that originally made RF tracking devices for falcons in the Middle East. Having the falcon up in the air (and not over a hill) makes for better line-of-sight RF propagation, but still, these transmitters are tiny!

Hope that helps. Welcome to the PF, BTW.

Thanks for the information. The link shows the transmitter but does this tranmitter have to have a line of sight to work? The terrain is hilly and sometimes dense woods. Do you think that product may work? Do you know of any type of GPS or GMS systems?

GPS would only be for mapping the dog's path after you get him back -- it's a receive-only device that the dog wears.

This link out of the google hit list looks to be a pretty good source of information about dog tracking collars:

The frequencies that I see being mentioned in the links in the hit list are mainly VHF and UHF frequencies, which are basically line-of-sight, and won't carry over the tops of hills. However, in the link above, they claim their system works to about 2 miles "in adverse conditions" whatever that is -- maybe raining in the woods? You might try giving their Customer Service folks a call to get more information. You might even be able to get some references of satisfied customers from them, and give them a call to talk about how well the system works.

I've noticed in many of the links that these systems are pretty pricey, though. You may need to do some shopping around to find some lower-priced systems.

I really would like to try to find something real time that I can watch on a hand held unit. sort of like a gps for a car, when driving my vehicle I can see my movement. I indicated earlier the size of a watch battery but I think my cylinder I can use will accomadate the size of a pencil. Any such device availible out there.
 
I gave this some thought how big are the gps that are in the cell phones. They have to be small? Anyone know?
 
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
