can anyone out there recommend a cheap way to gauge subsurface water temps? i don't need anything special, just a way to see what the water temp is down to 50 ft or so. the few devices i've seen out there are several hundred dollars which is pretty extreme for a thermometer!
any advice would be appreciated.
Just get an oral thermometer, tape/velcro it to a downrigger snubber and away you go.
this is the cheapest way but you have to drain the water out every time you check it. you can put it right on the down rigger cable.
that's a great idea forry but i was hoping for something a bit more creative/accurate.
the vexilar device is just what i was looking for - cheap and hopefully fairly accurate...thanks!!!!!!!
I guess I am an old yankee. that is a great looking rig. it must tell you how deep you are by measuring the pressure??? not really sure. but it looks good and no need for velcro or tape.
the water pressure must equalize with the spring tension that opens and closes as the unit goes deeper
