About
PROBE Lure Tracker is an innovative smart fishing sensor designed to give anglers data-driven insights that were previously impossible to obtain. The small, waterproof device (1.3" long, 0.25 oz) attaches directly to your fishing line via a through-center attachment and is rated to 200 ft (60 m) depth. Using Bluetooth Low Energy 5.0, it syncs data to a companion smartphone app whenever you're above water. The sensor captures real-time lure depth, swimming speed, water temperature at each depth, turbidity (water clarity/light levels), and strike indicators. This allows anglers to identify the thermocline zone — where temperature changes most significantly — which is critical for targeting fish species at their preferred feeding depths. The companion app provides a full lure journey graph showing how your lure behaves during reel stops, rod twitches, and various retrieval techniques. Every cast is automatically logged, even with your phone in your pocket, capturing both successful and unsuccessful casts for comprehensive session analysis. Weather and GPS location are recorded alongside sensor data. With 34+ hours of battery life and magnetic USB-C charging, PROBE is built for extended fishing trips. It ships internationally within 24 hours at a one-time price of $149. PROBE is ideal for freshwater and saltwater anglers — from bass and muskie hunters to open-water trollers — who want to refine their technique using real underwater data rather than guesswork.
Key Features
- Real-Time Depth & Temperature Tracking: Monitors your lure's exact depth and water temperature throughout the entire water column, rated to 200 ft (60 m).
- Strike & Speed Indicators: Captures the exact depth at which fish strike and tracks lure swimming speed, giving anglers actionable performance data.
- Automatic Cast Logging: Every cast is automatically recorded — including unsuccessful ones — along with GPS location and weather data, without requiring you to watch your phone.
- Thermocline Zone Detection: Unlike fish finders, PROBE maps temperature shifts throughout the entire water column to help you find the thermocline and target fish at their preferred feeding depth.
- Long Battery Life & Easy Charging: Offers 34+ hours of battery life with magnetic USB-C charging, making it suitable for multi-day fishing adventures.
Use Cases
- Identifying the thermocline zone to target fish species at their preferred feeding depth during seasonal temperature changes.
- Analyzing lure behavior — such as how reel stops, twitches, and different line types affect depth — to refine retrieval techniques.
- Logging full fishing session data (successful and unsuccessful casts) for post-trip analysis and planning future outings.
- Comparing how different lure designs perform underwater in terms of depth and speed characteristics.
- Pinpointing strike depth across multiple sessions to build a data-driven understanding of where fish are feeding in a specific body of water.
Pros
- Unprecedented Underwater Insight: Provides data on lure depth, speed, temperature, turbidity, and strikes that was simply unavailable to most anglers before.
- Hands-Free Automatic Logging: The app logs all cast data automatically — even with your phone in your pocket — so you never miss a data point while focusing on fishing.
- Compact & Durable Design: At just 0.25 oz and 1.3" long, the sensor is small enough not to affect lure action and is rated to 200 ft depth.
- Comprehensive Session History: Records every cast (not just catches) with weather and location for thorough post-session analysis and future trip planning.
Cons
- One-Time Hardware Cost: At $149, PROBE requires an upfront hardware purchase, which may be a barrier for casual or budget-conscious anglers.
- Bluetooth Sync Only Above Water: Data syncs via BLE 5.0 only when the sensor is above the waterline, so real-time monitoring during a cast is not possible.
- Limited to Lure-Based Fishing: Designed specifically for lure/cast fishing; may not be suitable for all fishing styles such as fly fishing or stationary bottom fishing.
Frequently Asked Questions
How does PROBE attach to my fishing line?
PROBE uses a through-center attachment with standard float stoppers, allowing it to be rigged directly onto your fishing line above the lure.
How deep can PROBE go?
PROBE is rated to 200 ft (60 m), making it suitable for most freshwater and nearshore saltwater fishing scenarios.
Does the app work automatically or do I need to interact with it?
The app automatically logs every cast — including location and weather — even when your phone is in your pocket. You can review the data at any time during or after your session.
How long does the battery last and how do I charge it?
PROBE offers 34+ hours of battery life and charges via a magnetic USB-C cable included in the package.
What data does PROBE collect?
PROBE tracks lure depth, swimming speed, water temperature at each depth, turbidity (light level at depth), strike indicators, GPS location, and weather conditions — all automatically logged per cast.
