I’ve run a Butterfly iQ+ off a 20,000 mAh power bank since 2022 for chelonian coelomic scans and wallaby pouch checks, packed in a Pelican 1120 with silica, but in wet season rainforest heat (about 35°C) it overheats and drops frames. Before I spring for a used SonoSite with a 13–6 MHz linear, what portable unit and probe covers are holding up for you on muddy callouts and boat landings?
Got stopped during a 6–8 check last fall and the officer accepted my email receipt, so I always “screenshot your receipt” in case the portal hasn’t updated yet. At dusk the tags are hard to read — reflective or silicone tag holders help, and make sure your microchip info matches the license so a lost dog gets home fast; think of it as a hall pass for your pup.
Clarius L7 HD3 stayed stable at ‘35°C’; OB sleeves over CIVCO covers handled mud. Lumify L12-4 was fine, phone overheated.
