From radar to capture: the action begins
Ready to go from colored circles on your screen to real-life tugs on your rod? Today you can turn your phone into the most reliable tool in your tackle box.
Open the app, check your battery, and make your first cast: in seven days, you'll master your radar and watch the hooks return charged.
From screen to hook: integrate radar into your routine
A portable sonar only makes a difference if you use it consistently. Just like training a new knot or fine-tuning your reel's drag, you need to practice readings, calibrate sensitivity, and learn to interpret lines and arcs. This field plan blends theory with light action: short sessions that fit into any schedule, from time at the dock after work to a Sunday kayak outing. At the end of the week, you'll have your own bathymetric map, a logbook, and the confidence that your future trips will get off to a head start.

Weekly testing plan: dock, kayak, and shore
• Monday – Initiation test (20 min)
Download the local area; launch the sonar next to the dock and perform 5 m circular sweeps. Mark three waypoints: rocky bottom, kelp bed, and possible school of fish.
• Wednesday – Kayak tour (45 min)
Drag the device at a slow speed. Switch from wide to narrow beam every 100 m to compare details. Record GPX tracks and label the temperature.
• Friday – Launched from shore (30 min)
Use your rod to position the radar exactly where you suspect activity. Observe the structure's pattern: if you see a firm arch mid-column, drop a suspending lure; if the echo is close to the bottom, opt for a leaded vinyl.
• Saturday – Night show (25 min)
Return to the same spot at dusk, repeat the scan, and set the sensitivity to low to eliminate noise. Note the differences: many fish change depth as the light fades.
• Sunday – Complete mapping (60 min)
Combine the week's tracks and generate a bathymetric map in the app. Export to KML, upload it to Google Earth, and check out hidden pools, bends, and depressions. Plan your next outing by casting right into those "sweet spots."
Typical faults (currents, interference, battery)
- Strong current dragging the float: secure the sonar with an elastic recoil buoy or a light lead counterweight.
- Interference from other Wi-Fi devices: Change the channel in the app or move your phone 30 cm away from your Bluetooth-enabled camera roll.
- Sensitivity too high: false echoes (noise) will appear. Lower it one notch when the water is cloudy.
- Battery life to the limit: Airplane mode + Wi-Fi Direct on sonar saves up to 25 % of charge. Carry a power bank in a waterproof case.
- Minimum depth ignored: Many models require 0.5 m to read clearly; if you're fishing in a pond, release a short line and keep the sonar still. Avoiding these pitfalls prevents frustration and allows you to focus on placing the bait where there's real movement.
Analyze your logs: bathymetric maps and catch diaries
After finishing the route, open the history and review:
• Depth versus time. If the school rose at dawn, schedule your casts early.
• Temperature and activity. Note whether the arcs became denser at 18°C; this number will be your reference for comparing other days.
• Type of bottom drawn. Solid lines indicate rock; diffuse lines indicate silt. Adjust the weight of the lead accordingly.
• Echo-free points. A clean gap can reveal a current inlet: ideal for lurking predators.
Export each session as a CSV and, once a month, create a simple chart: "date" versus "number of bites." You'll see that the days you tracked the radar reading clearly outperformed those you blindly tracked. Also, add photos of the catch linked to the waypoint: when you review the map, you'll remember which lure and technique worked where.
By integrating these reviews, technology ceases to be a curiosity and becomes a tangible increase in your success rate. In less than a month, your track record will show not only blue runs but also trophy marks that support your new method.

When the sun goes down and you close the app, don't forget to celebrate every lesson: that cluster of arcs you guessed right, the bite that landed right where the 2D/3D fish landed, or the battery life that lasted thanks to your saving routine. The water will still be a mystery, but you now have a sonar flashlight in your pocket. Cast with confidence; the fish aren't playing hide-and-seek anymore, they're just waiting for you to come and find them.
