Campers with young kids, need a new baby monitor

We had one almost identical to this one. It had belt clips on the back too. This thing was great. We dedicated it to the camper just for that purpose. The SD state parks sites are HUGE and we could easily go sit with friends at the next site. They are very sensitive and can pick up the slightest peep based on your settings. Not cheap but well worth it.
Pretty sure we bought ours at wally world.
