Key Features & Benefits

Bluetooth Remote-Control Technology

Crosstec is one of the first manufacturers to introduce Bluetooth technology into agricultural sprayers. Through wireless Bluetooth control, users can remotely manage spraying operations, adjust settings, and improve work efficiency in large-scale agricultural applications.

• Wireless Bluetooth operation
• Improved spraying convenience
• Reduced manual operation
• Suitable for orchards and large farms
• Enhanced spraying accuracy

Intelligent Variable-Speed Control

The integrated variable-speed system allows operators to precisely adjust spraying output according to crop requirements, weather conditions, and chemical application needs.

• Stepless speed adjustment
• Uniform spray coverage
• Reduced chemical waste
• Better crop protection efficiency

High-Performance Diaphragm Pump

The industrial-grade diaphragm pump delivers stable pressure and reliable performance for demanding agricultural environments. Combined with constant-pressure technology, the sprayer maintains consistent atomization from start to finish.

• Stable pressure output
• Long pump lifespan
• Excellent atomization performance
• Suitable for continuous professional use

Large 15L Tank Capacity

The 15-liter tank capacity provides extended spraying coverage while minimizing refill frequency. It is suitable for orchards, vineyards, vegetable farms, greenhouses, and landscaping projects.

Ergonomic Backpack Design

The ergonomic carrying system features adjustable shoulder straps, breathable back support, and balanced weight distribution, ensuring operator comfort during extended working periods.

Chemical-Resistant Construction

Manufactured from high-strength polypropylene materials, the tank offers excellent impact resistance, UV resistance, and corrosion resistance for long-term outdoor use.

1. Core Differences

2.1 Adjustment at Your Fingertips – No Extra Motion

Traditional knob:  Want to adjust flow? Stop → bend or squat → find the knob on the lower body → turn it → straighten up → continue walking.  5–10 seconds per adjustment, severely interrupting workflow.

Bluetooth handle speed control:  The spray gun is always in your hand, thumb naturally rests on the +/- buttons.  Adjust while walking – flow changes instantly.  No stopping, no looking down, no posture change.

Clear efficiency gain:  50 adjustments per day – traditional method wastes 5–8 minutes on "bending to find the knob." Bluetooth handle speed control converts those 5–8 minutes  completely into productive spraying time.

2.2 No Need to Look Down – Always Eyes on Target

Traditional knob:  Every adjustment requires  looking down to locate the knob . When you look back up, you may have missed a section of crop, or the spray gun direction may have shifted.

Bluetooth handle speed control:   Eyes stay on the crop or spray surface at all times.  Thumb operates +/- buttons blindly – spray gun direction unchanged, spraying continuous without interruption.

Advantages:

Reduced missed or overlapping spray areas

Improved spray uniformity

Lower safety risk (especially when working near roadsides or ditches)

2.3 Real-Time Tactile/Audible Feedback – You Always Know Where You Are

Traditional knobs have no feedback – how much have you turned? What setting are you on? You can only guess or look back.

Bluetooth handle speed control typically includes the following feedback methods:

Advantages:

Confirmation with every press – no need to look at a screen or knob

Zero-error blind operation

Clear alerts when reaching min/max limits – no wasted adjustments

2.4 Hands Work Together – Spraying and Adjusting Simultaneously

Traditional knob:  During adjustment,  one hand must leave the spray gun  to turn the knob – spraying stops. If the other hand is holding the hose or pushing aside branches, things get even more chaotic.

Bluetooth handle speed control:   Spray gun never leaves your hand.  Thumb adjusts while index finger continues pulling the trigger. If you need to push aside branches, your other hand is free to help – unaffected.

Typical scenarios:

Orchard worker: one hand pushes aside dense foliage to expose fruit clusters, the other hand holds the spray gun for precise application – while adjusting flow to match different branch densities

Disinfection worker: one hand pushes the sprayer, the other holds the gun – adjust while walking, no need to put down the gun

2.5 Adapts to All Hand Types and Working Conditions – All-Day Comfort

Advantage:   True ergonomic design  – the machine adapts to the hand, not the other way around.

2.6 One-Touch Preset/Memory Function (Advanced Models)

Some Bluetooth handles support two or three preset settings, for example:

Short press "+"  : stepwise flow increase

Long press "M"  : save current flow as preset

Double press "M"  : switch to preset mode

Advantages:

One-touch switch between "fine mist mode" and "jet stream mode" – no need to step through gradually

Multiple users sharing one sprayer – each can save their own preferred settings

Quick recall of parameters for different crops or seasons

5. One-Sentence Conclusion

Traditional knob makes you "stop → bend → look → turn → straighten → continue." Bluetooth handle lets you "adjust while walking." The former is physical labor; the latter is instinct. If you adjust flow more than 20 times per day, Bluetooth handle saves not just time – but also your back and your fingers.
