Abstract
A shower array exploiting the full coverage approach with a high segmentation of the readout allow to image the front of atmospheric showers with unprecedented resolution and detail. The grid distance determines the energy threshold (small energy showers are lost in the gap between detectors) and the quality of the shower sampling. Therefore, this experimental solution is needed to detect showers with a threshold in the 100 GeV range. The full coverage approach has been exploited in the ARGO-YBJ experiment. In this contribution we will summarise the advantages of this technique and discuss possible applications in new wide field of view detectors.

Report
The paper addresses a possible approach to detect photons with the full coverage muon detectors. Mainly, the advantage of this technique and possible applications in wide field of view detector are well discussed.
This manuscript is well written and interesting to read, however, I have the following minor comments for revision consideration.
Requested changes
1. page 4, in Fig. 3 (left) legend, “N_pi alpha delta” should be “N_pad”.
2. page 6, What stands STACEX for?
3. page 6, in the middle: (b) a dense muon detector array below the carpet constituted by water Cherenkov tanks buried under 2.5 of soil; It should be “under 2.5 m of soil”.
4. page 6, line 8 from the bottom: 20,000 m^2 → 22,500 m^2
5. page 6, line 4 from the bottom: “Results of a preliminary calculations are shown…” should be “Results of preliminary calculations are shown…”.
6. page 7, line 5 from the bottom: Section 4 states that STACEX has a very good energy resolution (20% or better) above a few tens of TeV, but here “The energy resolution is about 50%.”?
7. page 8, in third paragraph, there is no end between multiplicity and We.
8. page 8, in third paragraph, “as a function of the number of strips” should be “as a function of the primary photon energy”.
9. page 9, What is the altitude of STACEX? In Fig. 8 the sensitivity of STACEX (solid red line) is similar to the one of LHAASO, which has about twice larger area. What could be the reason for that? Is it due to the full coverage muon detector? But LHAASO has full coverage detector with a wide field of view as well.
10. page 9, What is the effective area and the altitude of SWGO? Please put the reference for SWGO.
11. page 9, in Fig. 8 legend, 22000 m^2 → 22500 m^2
12. page 9, in the caption of Fig. 8, there is a typo. STATEX should be STACEX.
