Does anyone know of any digital thermometers that can read water temps at various depths by lowering a sending unit down to different depths?
Would a Lowrance extension cable with blue connectors read properly if the connectors where submerged under water? I have an extra transducer for my Lowrance, but the cable is only about 16 feet long.
I'm interested in getting water temps at 20-30 feet down.
Thanks, Dan
i don't see why a regular transducer wouldn't work with an extension cable and a long pole or something. or tie a weight to the transducer and drop it by hand. just wrap the connector in electrical tape or something.
I called Lowrance and found out they have a 20' transom extension that will work with my LCX20C. They said just waterproof the connector, so now I just have to find that spare transducer so I don't have to buy a new one.
Curious as what you need this data for.
I'm thinking the crappie at Clinton Lake are still deep, not realizing the shore line temp is 60 degrees. Clinton had 22" of ice on it this winter so I'm thinking the deeper water is taking longer to warm up, so the crappie don't sense warming water at the surface.
I'm just a curious person trying to figure out crappie, if that is possible.
I am a person that always needs to know why or how things work.
It would be cheaper to buy one of those glass thermometers that you can attach a string to and drop it down for couple of minutes and then pull it up and read the temp.
I used a Vexilar 104 Deptherm Thermometer. Costs about $10
It retains a water sample from the depth you stop at so it reads right when you bring it up. Gander Mountain link

This is very interesting and sounds worth the money, just for curiosity use. Try Vex's main web site as Ganders was sold out.Quote:
