## Most critical reviews (4 lowest-rated)

### 1/5 — Broken unit conversions

*2021-07-02*

Knotmeter readout displayed in degrees by default. Depth label changes to feet, but clearly still meters. Same for temperature.

### 2/5 — Needs work

*2025-09-16*

1. Settings menu is confusing bc it only gives units options while all all other settings require swiping left which I had to locate the manual to figure out. 2. Pressing plus sign sets up another device page so now I have two useless ones from trying different things, and now the app is “hanging” and resets every time I swipe past the useless device pages. Make the pages editable to remove modules and delete the page. 3. Work with BnG to have Airmar DST 810 option on Zeus chartplotter setup. I had to select “generic”.

### 2/5 — Units are incorrect

*2022-01-02*

No matter the setting the app report temp & depth units in C and meters.

### 4/5 — Used with new DST820

*2026-07-09*

I installed the DST820 on my boat and used the app to configure the output.  Havent used it to calibrate my speed but it looks pretty straightforward
