Moisture meters
Holes and precision, or no marks and depth?
A pin meter measures resistance between two probes at a known depth; a pinless one reads a capacitive field over a volume. The first is more specific and leaves marks; the second surveys a finished wall and averages everything under it, including any metal.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Buy the pin meter for timber, firewood and anything that will be cut or covered. Seven calibrated scales and two published figures make it the better instrument where holes do not matter.

Buy the pinless meter for finished walls and floors. A survey means dozens of readings, and dozens of pin holes in a decorated room is not an option — accept that it averages whatever is in the 40 mm (1.57 in) under the sensor.
The pin meter, on the material it is calibrated for, at the depth its pins reach. The pinless meter is more useful, because it can be used where the pin meter cannot.
No. Both find a difference. Rising damp, a leaking pipe, condensation and splash-back all read the same, and separating them belongs to someone qualified to assess the building.
Pin type · ± 2.0% stated · 0.10% resolution · 4 wood + 3 building scales
A pin meter publishing both its accuracy and its resolution — ± 2.0% and 0.10% — with seven calibrated scales split between four wood groups and three building materials.
Best for: Timber and firewood, where a pin reading at a known depth is exactly the right measurement.
Pinless ball sensor · to 40 mm (1.57 in) depth · DRY / MID / WET · adjustable alarm · hold, max/min
A pinless meter with a ball sensor reading to a stated 40 mm (1.57 in) depth, showing DRY, MID or WET alongside a value, with an adjustable moisture alarm.
Best for: Surveying a finished wall or floor, where holes are not acceptable and depth matters.
