Hi all! I am looking for a laser that can be seen outdoors in full sunlight. I am an arborist and use lasers to point up into tall tree canopies up about 100ft tall, nothing close. I have previously bought a 120nm (2)aaa laser (can’t remember the brand) that’s not getting the job done. Right now I’m looking at a Sanwu 1W 520nm Guardian laser. Let me know your thoughts. Is that enough laser? Are there better options? Thanks!
