The simplest set-up would be to get a 'naked' spg/hp hose and a wrist mounted depth w/temp gauge...If you can find one that DSS or some one else makes that can be bungee mounted you'd be as stream lined as you can get.....I agree w/ron-----Get a good quality analog spg/depth/temp...[glass lens/brass housing] and a standard HP hose...They're reliable and many are on sale new or here on SB.......
