I don't know if this is old hat to most here but I love these things. Just point and shoot at the water, read the temp and fish accordingly. I used to have an Orvis one but they went out of production and I lost mine. I Googled Infrared Thermometer Fishing and found a couple of good options.
Harbor Freight has a pocket sized one for electricians and such for $12. A bargain there... I found a sexier one on Amazon for $30 that looks to be durable and handy to stow in a pocket. It's a nice metal tube, just point and click. https://www.amazon.com/gp/product/B08L6RPJZD/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1
These are kind of fun. You can see how hot your dog is, check the hot tub, take your own temp, or not.
