"Forget about trolling charts"
– Dan, Manistee US
PR0BE is a smart sensor for your fishing line. It tracks your lures depth, water temperature, light and movement. Use it when trolling, casting or coarse fishing, to get insights only dreamed of.
Stop Guessing Learn the exact depth of your lure at different speed of your vessel. Watch how temperature and light shift as you move through the water. Compare today’s route to last week’s. Find what the good days had in common. Build a real picture of your fishing — not a guess.
PR0BE is very lightweight (0.25oz / 7gram), and attaches directly on your fishing line. It's hydro stealth design and center attachment makes it swim through the water unnoticeably and wont affect the presentation of your lure.
Charge PR0BE for 2 hours and you're ready to go for up to 32 hours! It does not have any buttons – not even a on / off switch. But its clever algorithms and sensors keeps track of every action and distributes its power to when the action happen so you can enjoy seamless augmented fishing.
Find that Thermocline Unlike Sonar and fish finders, PR0BE proved insight throughout the entire water column. Get insight into where the temperature peaks or drops and let PR0BE guide you to your target depth.

Our Story
"How deep is my lure right now? Am I near the bottom?" That's the question PROBE was built to answer, back in 2018. A simple, common question — yet no one had ever really answered it. Every angler's expensive lure was behaving underwater on pure guesswork. We're a small team of engineers, an award-winning designer, and software developers — some lifelong anglers, others new to fishing through this project. We knew anglers spend hundreds of dollars a year on lures without ever knowing how they actually behave underwater. You cast, retrieve your $15 investment, and hope for the best. We couldn't shake the idea that today's technology should change that. So we filed a patent and got obsessed with the answer. Rather than ordering finished units from China, we launched a Kickstarter — and it worked. Stubborn about owning the manufacturing ourselves, we built a small factory and assembly workshop here in Sweden. A year later, we shipped our first batch. Today, PROBE is trusted by thousands of anglers worldwide.
