Pica 2020 Deep Hole Spray Marker is a hand-powered marking tool made for pros who need to place clear reference marks inside drilled holes and other tight access points. This is a deep hole spray marker designed for non-contact marking in drilled holes and hard-to-reach spaces. Model number 2020. If you do electrical, plumbing, construction, or general installation work, this tool solves a simple but real jobsite problem: getting an accurate mark where a regular carpenter pencil, marker, or scribe cannot reach.

The big advantage here is reach. The Pica 2020 Deep Hole Spray Marker is built to mark through openings as small as 3 mm and reach depths up to 25 cm, which is about 9.8 inches. In practical terms, that means you can transfer hole locations, mark behind fixtures, or identify drilling points in deep cavities without guesswork. When you are working around mounting holes, anchors, boxes, or hidden fastening points, that saves time and reduces bad holes and rework.

Instead of making contact like a traditional marker, this tool uses a spray-style chalk marking system. That matters because it lets you mark surfaces you cannot physically touch with the body of the marker. The result is better access in cramped spots and less fumbling when you are trying to work one-handed. For installers and service trades, that is the kind of small design difference that speeds up layout all day long.

The 360 degree spray nozzle adds another layer of jobsite usefulness. You are not locked into one approach angle, so it is easier to work around obstructions, inside cabinets, around plumbing fixtures, or inside enclosures. If you have ever had to twist your wrist into a bad position just to reach a mark point, this feature makes sense right away.

Visibility is another strong point. The marker uses high-visibility green chalk, which is meant to stand out clearly on a range of common jobsite materials. That makes it easier to spot your reference point before drilling, fastening, or cutting. For layout work, a mark that is easy to see is not a cosmetic detail. It directly affects speed and accuracy.

Pica also built this marker for repeat use instead of short-term throwaway use. The refillable system is rated for up to 1,500 shots per fill, which gives it a longer service life than a one-and-done specialty marker. If this is a tool you pull out regularly for cabinet installs, electrical rough-in, plumbing fixture work, or anchor layout, refillability matters because it keeps your cost per mark down.

From a user standpoint, the one-hand operation is a big deal. Specialty marking tools are most useful when the other hand is busy holding material, a fixture, or your body position. This design is aimed squarely at real installation work where access is limited and speed matters. It is not a general-purpose paint marker or standard layout pencil. It is a problem-solver for specific marking jobs that are awkward with conventional tools.

Who should buy it? Contractors, electricians, plumbers, installers, maintenance techs, and serious DIY users who regularly need accurate fastening or drilling locations in recessed areas. If most of your marking happens on open, easy-to-reach surfaces, a standard marker is cheaper and simpler. But if you are constantly reaching into deep holes, behind fixtures, or inside boxes, the Pica 2020 Deep Hole Spray Marker earns its keep fast.
