I've tested the Deeper START Smart Fish Finder and found it to be a solid entry-level choice for shore anglers. This compact device weighs just 0.08 kg, generates its own Wi-Fi signal, and scans depths up to 165 feet with a 40° beam angle. The 6-hour battery life from a 2.5-hour charge worked well for my day trips, and I appreciate how it shows real-time data on fish locations and underwater structures through the Fish Deeper app. While I encountered some connectivity issues, and the battery life could be longer, its value proposition for recreational fishing is clear. Let me share what else I discovered about this castable sonar.
Castable Smart Sonar Device
With its compact 4.33-inch design, the Deeper START transforms into a powerful sonar device you can cast directly into the water.
I've found that this lightweight unit, at just 0.08 kg, easily attaches to your fishing line and casts smoothly into your target area.
Once in the water, it creates its own Wi-Fi signal to connect with your smartphone.
What I love about this castable sonar is its impressive 165-foot depth capability and 40° beam angle, which give you a thorough view of what's beneath the surface.
You'll get real-time data about fish locations, sizes, and underwater structures through the Fish Deeper app.
While it performs best in calm conditions, I've noticed it can still deliver reliable readings in moderate chop, making it versatile for different fishing scenarios.
Compact, Waterproof Fishing Sonar
The Deeper START's waterproof housing packs impressive sonar capabilities into a palm-sized device that's built to withstand complete submersion.
At just 4.33 inches in length and weighing only 0.08 kg, I can easily cast and retrieve this compact unit without straining my fishing rod.
I've found the 40° sonar beam provides excellent coverage, scanning depths up to 165 feet while revealing detailed information about fish location, size, and underwater structures.
What's particularly impressive is how this small package includes night fishing capabilities and generates its own Wi-Fi signal, meaning I don't need to burn through my mobile data while fishing.
The unit's 6-hour battery life from a 2.5-hour charge gives me plenty of time to explore multiple fishing spots during an outing.
0° Beam Sonar Reading
Scanning underwater terrain becomes remarkably intuitive with this START's beam sonar technology.
I've found that the 40° sonar beam provides excellent coverage, reaching depths of up to 165 feet while delivering clear readings of fish location, size, and underwater structures. When I cast the device, it instantly transmits detailed data to my smartphone through its Wi-Fi connection.
What I particularly appreciate is how the beam sonar distinguishes between different-sized fish and shows bottom contours with impressive accuracy.
I can easily identify vegetation patches and track fish movement patterns in real-time. During night fishing sessions, the dedicated mode maintains the same precise readings, helping me locate fish even in low-light conditions.
The beam's width offers an ideal balance between coverage area and detail resolution.
-Hour Battery Runtime
Running continuously at full capacity, my Deeper START delivers a reliable 6-hour battery runtime that proves more than sufficient for typical fishing sessions. I've found the 2.5-hour charging time to be reasonable, letting me quickly prepare for my next outing. When I keep my device properly charged, I never worry about running out of power mid-session.
| Battery Specs | Performance | Usage Tips |
|---|---|---|
| Runtime: 6 hrs | Full Capacity | Charge night before |
| Charge Time: 2.5 hrs | Wi-Fi Active | Monitor power level |
| Li-ion Battery | App Connected | Avoid partial charges |
| LED Indicators | Night Mode On | Store fully charged |
| USB Charging | GPS Running | Keep USB port clean |
For peak performance, I recommend charging your Deeper START completely before each fishing trip and avoiding partial charges whenever possible.
