He was the youngest son of Sir William Symonds, who was a Royal Navy Admiral and Surveyor of the Fleet.
He joined the Royal Engineers and was made 2nd Lieutenant in 1833, Lieutenant in 1836, 2nd Captain in 1845, Captain in 1850 and given the Army Rank of Major in 1846.
Following the intervention of the western powers in Syria and Palestine as a result of increasing tensions between Egypt and the Ottoman Empire Lieutenant Symonds was sent to the area in 1840. After surveying coastal forts he was sent to Jerusalem in early 1841, where he prepared an accurate map of the city. Later that year, at the age of only 26 or 27, he was ordered to carry out a complete trigonometrical survey of southern and central Palestine: the north would be surveyed by a different team. The survey was done by triangulation from the coast inland to the Dead Sea, using a 7-inch theodolite. Symond's calculations for the height of the Dead Sea was 1312 feet below sea level, compared with today's accepted figure of 1299 feet below sea level. In spite of the arduous conditions and sickness which affected the whole team, the exercise was completed in 10 weeks.
In 1843 he was awarded the Patron's Gold Medal of the Royal Geographical Society for "his triangulation over Palestine and for his determination of the difference between the level of the Mediterranean and the Dead Sea".
He died at Argostoli, Cephalonia in 1852.
