GoldSwell is a beach metal detecting intelligence app that forecasts when storms and swells strip sand from the beach to expose deep targets, black sand, and gravel patches. It uses real-time swell, tide, wind, and weather data to predict optimal beach hunting conditions.

How does GoldSwell predict beach cuts?

GoldSwell uses proprietary algorithms (the G-Swell engine) to analyse swell height, period, direction, tide, wind, and storm patterns at your specific beach coordinates. It calculates a Sand Stripping Index (SSI) and Substrate Exposure Index (SEI) that combine into a GLX (Goldilox Index) score from 0-100, telling you when conditions are optimal for finding old gold and deep targets.

What is a beach cut in metal detecting?

A beach cut is where ocean waves have stripped away layers of sand to expose deeper, older material beneath. Beach cuts reveal hard-packed layers, gravel patches, and black sand — all indicators of where heavy items like gold rings, coins, and relics have settled over decades. Experienced detectorists know that beach cuts are the most productive areas to hunt.

What is black sand and why is it important for metal detecting?

Black sand is a concentration of heavy minerals (primarily magnetite and ilmenite) that accumulates when lighter sand is washed away by wave action. In metal detecting, black sand is a key indicator of productive areas because gold, being heavy, settles alongside these minerals in the same layers. Finding black sand means you are detecting in an area where heavy objects have concentrated.

Is GoldSwell free to use?

Yes. GoldSwell has a free SCOUT tier with a 14-day full-access trial. Paid plans currently start at $1.99 per month for HUNTER, while SNIPER is $4.99 per month. Annual options and one-time G-Spot packs are also available.

Are my beach locations private and secure?

Absolutely. GoldSwell is built on encrypted Cloudflare Edge infrastructure. Your G-Spot coordinates are encrypted end-to-end and never shared with other users. Your spots stay yours — location privacy is a core design principle.

The Problem

Others Drive Blind.
You See the Cut.

Most detectorists rely on guesswork, Facebook posts, and driving to the beach to check. GoldSwell replaces hope with data.

The Beach Changes Every Tide

Yesterday's hot spot is today's dead zone. Sand shifts, cuts fill in, new layers get buried. You can't trust what you saw last week.

Wasted Drives, Wasted Days

You drive an hour, walk on, and see flat sand. No cuts, no gravel, no hard pack. The beach wasn't ready — you just didn't know.

GoldSwell Reads It For You

Real-time swell, tide, wind, and storm data — processed to predict when and where the beach strips down to the good layers.

About

What Is GoldSwell?

GoldSwell is a beach metal detecting intelligence app that forecasts when ocean storms and swells strip sand from your favourite beaches. By analysing wave energy, swell direction, tidal patterns, and storm systems in real-time, GoldSwell calculates a proprietary Goldilox Index (GLX) that tells you exactly when conditions are right for finding old gold, rings, coins, and relics buried in the deep layers.

Instead of driving to the beach and hoping for the best, GoldSwell shows you which beaches are actively cutting — exposing black sand, gravel patches, and hard-packed substrate where heavy objects have settled over decades. It's like having a geologist and a weather forecaster dedicated to your metal detecting spots, running 24/7.
