TX-850 Metal Detector: Finding Gold 8 Feet Underground for $92

When Metal Detecting Became More Than a Hobby

Last spring, my neighbor mentioned finding old coins while renovating his 1920s farmhouse foundation. That got me thinking about what might be buried in my own century-old property. I wasn't ready to invest in a $300 professional detector for what might be a passing interest, but I wanted something that could actually find metal deeper than surface level. The TX-850 appeared in my research with specs that seemed too good for the $92 price point: 8.2-foot detection depth with discrimination features.

My Honest Take After Two Months of Use

I tested this detector across different terrains - sandy soil, clay-heavy ground, and rocky areas. The build quality surprised me right out of the box. The assembly takes under five minutes without tools, and the materials feel substantial rather than toy-like. The 11-inch search coil covers good ground efficiently, and the adjustable sensitivity actually works as advertised.

What impressed me: It detected a Mercury dime at 14 inches deep in compacted soil near my driveway. The metal discrimination feature saves significant time by filtering out iron junk while alerting to valuable metals. I found three silver coins and various jewelry pieces that had been lost for decades around the property.

The real limitation: Battery consumption is aggressive. With audio enabled, two 9V batteries last roughly 4 hours maximum. You'll need backup batteries or a portable charger for extended sessions. The audio can't be volume-adjusted, though that's fixable with basic electronics knowledge.

What $92 Usually Gets You

At this price point, you typically find basic detectors limited to 12-18 inch depth or toy-grade units that struggle with anything beyond surface coins. The TX-850's 8.2-foot depth capability puts it in competition with $200-300 detectors. For context, a Bounty Hunter TK4 Tracker (a popular budget option) costs $130 and maxes out around 3 feet.

The trade-off is brand recognition and warranty support. This is a well-engineered Chinese detector versus established brands with better customer service infrastructure. Functionally though, it performs like equipment costing twice as much.

Buy It If... / Skip It If...

Buy it if: You want to try metal detecting without a major financial commitment, you're looking for weekend hobby equipment for beaches or fields, or you need legitimate depth capability on a budget. Also ideal if you already own 9V battery charging equipment.

Skip it if: You plan daily professional use, you're unwilling to manage battery consumption issues, or you strongly prefer established brands with local technical support.

My verdict after finding $47 in old coins: This detector delivers more capability than its price suggests. It won't replace professional equipment, but it's legitimate gear that finds real treasures.

Score: 7/10 - Performs well above its price point.

Price: $92.55 (was $193.00)
