TABLE A2.

Scores from a written usability survey completed by five observers that participated in night‐time surveys using four devices to detect artificially heated Plains‐wanderer (P. torquatus) models in native Victorian grassland.

Survey questions	Spotlight	Low‐resolution thermal scope	High‐resolution thermal scope	Handheld thermal scanner
I was able to easily follow the transect for the whole survey, and I did not lose track of the transect line	25	10	20	22
When I detected a model Plains‐wanderer within 5 m of the transect line, I could see it clearly with the device	23	14	25	25
When I detected a Plains‐wanderer model with the device and walked out to check, it was always a Plains‐wanderer model rather than another, mis‐identified object	19	10	22	20
I found the device comfortable to hold when in use	23	17	20	22
I did not have to take breaks during surveys due to the device	16	14	21	20
I was able to quickly and easily learn how to use the device	25	23	24	18
I would recommend this device for ecological surveys targeting small endotherms	15	6	25	23
Total	146	94	157	150

Note: Answers were given as a score out of 5 (1 = strongly disagree, 3 = neutral, 5 = strongly agree), such that each score is out of 25, and the total score for each device is out of 175.
