Manufacturer documentation checked 3 October 2026. Named manufacturer documentation; the offered market and exact item require separate confirmation. No hands-on test is reported.

The display interval and the accuracy field are separate

Trend’s DAF/8 page lists resolution as 0.05 degrees, or three arc minutes, and lists accuracy separately as 0.15 degrees. The page does not justify replacing the latter with the finer display interval. These are the manufacturer’s fields for this named model, not an independent calibration result. The distinction is important when a tool comparison highlights the number of decimal places while leaving the accuracy entry out.

A digital readout can make an angle feel more certain simply because it is expressed precisely. Yet the form of a displayed number is not evidence of how closely the complete measurement corresponds to the quantity being measured. An editor comparing angle tools should preserve both fields and their original units. Do not infer an accuracy guarantee merely from the smallest change the display can show.

Convert units without upgrading the claim

There are sixty arc minutes in a degree, so the stated 0.05-degree interval corresponds to three arc minutes. That conversion explains why the two resolution expressions are consistent; it does not provide a second independent performance test. For a comparison sheet, it is reasonable to put tools into a common angular unit, provided each entry retains whether it describes resolution or accuracy.

Keep the manufacturer’s accuracy wording as documented. Do not add an unstated statistical confidence level, calibration certificate or environmental test condition. If those details matter to a precision task, the useful next step is to request supporting documentation. A neat-looking comparison table becomes misleading if empty evidence fields are filled with assumptions that the original source never supplied.

Define the task before declaring a winner

A tool intended to record a layout angle is being evaluated for a different question from a system used to certify a component. Write the intended measurement question in the comparison and identify the required evidence. A model can be convenient for one task without its product page answering the full traceability requirements of another. This article does not select an instrument for regulated inspection or machine alignment.

It also gives no saw, router or machine setup instructions. The page includes application examples, but copying them into this article would not verify a particular machine or operator situation. Here the useful lesson is to keep measurement claims correctly labelled before a purchase discussion reaches the workshop operation.

Retain the regional boundary

The consulted listing identifies the model as UK sale only. That is a source scope, not a claim about Oodworking’s operating country or every possible distributor. Verify the actual supplied model, market support and documentation for any offer outside that context. Current price, stock and hands-on performance were not checked. The evidence supports a clear comparison rule: read resolution and accuracy together, and leave missing test conditions visibly unresolved.

Evidence boundaries

Documentation interpretation only; no calibration, machine setup or inspection suitability approval. Accuracy sign and test conditions not supplied.
