# Geophone - SM-24

**Type:** Product page · **SKU:** SEN-11744 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/geophone-sm-24.html ([markdown](https://core-electronics.com.au/geophone-sm-24.html.md))

Need to put your finger on the pulse of the Earth? Did I just blow your mind? A geophone works by translating ground movement into voltage, which can easily be read by a microcontroller. The SM-24 geophone element is designed to offer the highest performance in seismic exploration based upon field-proven I/O Sensor technology. Low distortion, combined with excellent specifications, provide high-fidelity data. Basically, it’s a super low frequency microphone for the ground.

## Pricing

- **Price:** $129.95 (inc GST) — $118.14 AUD, exc GST
- **Quantity discounts:** 5+ $114.59 (exc GST) · 25+ $112.23 (exc GST) · 100+ $107.50 (exc GST)

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN-11744:1` (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/SEN-11744:1.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)
