  • Catch more fish! Have more fun!

ClineFinder helps you find fish-catching patterns faster
  with or without a sonar!

Fishfinders show you the bottom structure and the fish but they cant distinguish where those fish are most likely to bite. ClineFinder will help you find and catch the species youre after! Because fish are cold blooded, water temperature strongly controls:

  • location

  • feeding habits

  • activity level

  • aggressiveness

  • spawning. 

Bass, walleye, trout, salmon each species will seek its own temperature comfort zone. If a thermocline is present, hungry game fish will suspend just below that depth. By quickly measuring the temperature at a variety of depths in your lake or river, you can understand and use fish-catching patterns better than ever before!

ClineFinder is based on our famous AquaCal waterproof thermometer design which has been proven and refined over the past 5 years. ClineFinder responds incredibly fast to subtle temperature differences because of its ultra-small sensor design. Every ClineFinder is individually calibrated at 70F for extraordinary accuracy (0.5) in lakes, rivers, and ponds. ClineFinder is a quality scientific instrument, designed, manufactured, and supported right here in the USA!
