What is Kastave?
We love fishing. The quiet bank, the first cast, the feeling that the next spot might be the one. But unfamiliar water wastes time. Depth changes hide. Grass edges shift. Rock piles, submerged wood and drop-offs stay invisible until you have already committed.
Kastave is a compact AI fish finder robot that cruises your selected water area, scans underwater terrain, senses fish and water conditions, then turns that data into practical casting decisions.
Now you can scout before you cast.
Map the bottom. Find structure. Understand activity. Pick safer casts, structure targets or high-risk high-reward spots with clear AI guidance.
One press. Three scan experiences.
Adapt on the fly depending on water pressure, session urgency and how much disturbance you want.
Quiet Mode
Scout without spooking the zone.
Lower-disturbance cruising for calm water, pressured fish and close-range structure checks.
Performance Mode
Cover more water when time matters.
Faster scanning for banks, reservoirs and larger freshwater areas where you need a quick first read.
Auto Mode
Let Kastave adjust the route.
One-tap cruise for selected water areas, with obstacle-aware scanning and more detail around features like submerged wood, grass edges, rocks and drop-offs.
Engineering Prototype Test
From underwater data to practical fishing decisions.
Kastave combines sonar, sensors and AI recommendations into a simple scouting workflow.
3D terrain map
Sonar scans the bottom into point-cloud data and stitches the whole area into a terrain view.
Fish activity sensing
Detect fish size, distribution and bite activity signals from sonar and environmental data.
Water condition awareness
Depth, temperature, clarity and oxygen-related readings feed the recommendation model.
AI fishing coach
Recommends casting spots, rig choices and techniques based on the scan and fishing context.

How is Kastave different from 2D fish finders?
Traditional 2D sonar shows signals that anglers still need to interpret. Kastave is designed to turn underwater readings into a clearer 3D structure view for fishing decisions.
What fishing situations is Kastave built for?
Kastave is built for anglers searching banks, seawalls, canals, rocky shorelines, grass edges, drop-offs, submerged wood, and other structure-focused water.
Does Kastave guarantee bigger fish?
No device can guarantee a catch. Kastave helps you read structure more clearly so you can choose better casting targets and reduce blind searching.
Does Kastave need a phone app?
Yes. The intended workflow pairs the device with a mobile app for 3D scan viewing, saved maps, structure points, water conditions and trip history.
Can I use Kastave from the bank, kayak, or small boat?
Yes. Kastave is designed as a portable scan system for bank anglers, kayak anglers, and small-boat users who want structure information without a complex installed setup.
When will the first batch ship?
We are currently validating field performance, app workflow, and production planning. Early customers will receive launch updates before final purchase and fulfillment.
Where will you ship?
Shipping regions will be confirmed before final checkout based on logistics, taxes, and service coverage. Early customers will receive updates as launch details are finalized.
Which payment methods can I use for the reservation?
