I've been looking for a decent temp sensor with a long (10' to 20') probe for measure water temp at different levels in the pond this year. But I've just confused myself to the point I'm not sure what I'm even looking at any more.
My plan is to take the kayak out in to the pond once a week or so and measure the temp at different levels to start building a chart for reference.
I had one with a 4 foot probe, but loaned it out and it has never come home. Any suggestions?
