About the Minelab VANQUISH 340

The VANQUISH 340 keeps Minelab's Multi-IQ technology simple. Multi-IQ transmits several frequencies at once, so there is no frequency to pick and no ground balance to set, and Minelab gives the 340 three search modes: Coin, Jewelry and All Metal. Controls are kept to four sensitivity levels, three volume levels and five discrimination segments, and targets read on a ferrous scale of -19 to 0 and a non-ferrous scale of 1 to 40 with a four level depth indicator. Three target tones help you judge a signal by ear: Minelab describes low tones for iron, mid tones for valuables such as gold and high tones for silver.

Where the Minelab VANQUISH 340 fits

Parks, yards, sports fields and the dry and damp sand of a beach are the 340's ground. Coin mode is where we would start in a park, Jewelry where people swim and lose rings, and All Metal on old homesites where you would rather dig everything than miss an odd shaped target. Minelab rates the V10 coil waterproof to 1 meter (3.3 feet); the control box is not waterproof, so the coil can go into wet grass, puddles and the edge of the water while the control box stays dry. For hunting in the water, the fully waterproof VANQUISH 360 and VANQUISH 460 in the table below are the models to look at.

Weight, shaft and power

Minelab lists the VANQUISH 340 at 1.2 kg (2.6 lb). The shaft extends to 145 cm (57 inches) and collapses to 76 cm (30 inches) for a car trunk or a closet. Power comes from 4 AA alkaline batteries, which are in the box, so spares are easy to carry. Audio comes through the built-in loudspeaker or any wired headphones with a 3.5 mm (1/8 inch) plug; wired options are in our metal detector headphones collection.

Getting started with the Minelab VANQUISH 340

Put in the AA batteries, switch on and start in Coin mode on a patch of grass you know. Swing the coil low, level and slow, just above the grass, and overlap each pass by about half so a target between two passes is not missed. Lifting the coil at the end of each swing costs depth, so keep it low all the way across. Dig every repeatable signal for the first few trips so you learn what the three tones and the target numbers mean on your ground. Always get permission before detecting on private land. Our VANQUISH 340 getting started guide walks through assembly and the first hunt.
