My pet turtle...

Thanks, fellows.
The keyfinder seems the best choice for the task. Thanks, John.

A 1 MHz oscillator does not work. A 24 MHz in my parts bin does, with my portable shorwave receiver. But cells die fast in tests.

Bureaucracy, my pet turtle hides very well and am afraid of fatally hurt her with the lawnmower.
A flashing led attached to her back would allow me to find her but only at nights. A couple of coin cells could be made to last with one of those circuits that briefly pulse. Guys, I need your input to other options.

A different approach: Turtle Armor?

Here's a sample key finder. They make many types, this is just a "proof of consept". This particular model has a claimed range of 300 feet. $30.

Here's another version. Check out the glasses finder. Possibly something you could tie around the turtle.
