Sonar Frequency | Shallow to mid-depth fishing (200ft+) | Industry Standard: 83kHz (150ft max) Our Base: 200kHz (200ft) Our Advanced: 800kHz ▲ (400ft) | Better clarity in clear water; penetrates to deeper depths. ▲ Advanced: Ultra-high resolution for precise fish detection | Lower penetration in murky water; requires clearer water for optimal performance |
GPS Accuracy | Navigation in open water | Industry Standard: ±10m (basic GPS) Our Base: ±3m (GPS) Our Advanced: ±1m ▲ (GPS+GLONASS) | Precise waypoint marking for repeatable fishing spots. ▲ Advanced: Dual-constellation for stable signals in dense terrain | Higher cost for advanced models; requires satellite coverage |
Display Resolution | Daytime visibility | Industry Standard: 320x240px Our Base: 480x320px Our Advanced: 800x480px ▲ | Sharp sonar imaging for easy target identification. ▲ Advanced: Full HD for multitasking (maps + sonar) | Smaller screens may strain eyes in bright sunlight |
Battery Life | All-day fishing trips | Industry Standard: 6–8 hours Our Base: 10 hours Our Advanced: 14 hours ▲ | Extended use without recharging. ▲ Advanced: 40% longer runtime for multi-day trips | Heavier battery in advanced models may affect portability |
CHIRP Sonar | Structure scanning | Industry Standard: Basic single-frequency sonar Our Base: CHIRP (50–200kHz) Our Advanced: Dual CHIRP ▲ (50–800kHz) | Sweeps multiple frequencies for layered detail. ▲ Advanced: Discriminates fish from debris at extreme depths | Requires calibration for best performance in varying water conditions |
Waterproof Rating | Harsh marine environments | Industry Standard: IPX6 (water-resistant) Our Base: IPX7 (1m submersion) Our Advanced: IPX8 ▲ (3m submersion) | Survives accidental drops into water. ▲ Advanced: Deployable in rough seas or heavy rain | Higher ratings add bulk; advanced models may require专业 cleaning |
