Have you ever been wondering why and where the carps of your lake
are swimming ? Normally it would have been impossible to do an accurate
investigation about this, unless using a boat and echo sounder.
Now with the Prologic Substrate Finder Thermometer, you are able to
know exactly the water temperature in any water substrate.
So you can understand right away which water substrate is more suitable
for carps in that moment and place your hookbait in the right depth.
The Prologic Substrate Finder will give you an extremely effective extra
edge especially when fishing with zigs and when fishing deep waters.
