## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0599:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN0599:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This is an underwater ultrasonic obstacle avoidance sensor specifically designed for underwater applications. It operates on a wide voltage range of 5-24V and features compact size, minimal blind spots, high precision, and high protection. Its underwater measurement range is from 5-600cm.

With an IP68 protection rating, this sensor can replace a camera for obstacle avoidance and meet the requirements of normal underwater navigation speeds. By using this obstacle avoidance sensor, underwater vehicles can achieve true "unmanned driving" without the need for human observation. Even at a depth of 10m, obstacle avoidance can still be easily accomplished.

Thanks to its small size and minimal blind spots, this sensor takes up minimal space and can be easily integrated into various projects.
