Darn I really like the Ardent System but it is in lb and oz. I looked at both scales… do not like a scale that you can change for tents, oz, kg.. Just want something that is quick and easy and CORRECT anything that changes will change by acident and then you spend time trying to figure it out how to change the darn thing back, remember one I about throw in the water one day because it somehow (of course I did it but dont kown how) change from lb to kg. and I couldnt figure out how to get it back.. Grrrrrrr. Somedays you can really struggle to get 5 nice smallies on St Clair or Erie but then there are the days when the Cookie Cutters just wont stop coming and you culling alittle at a time 20 some plus fish. The Cul-m right a bit pricey but so is everything good Question is how easy to turn on and weight for me the best one would be an accurate lb/oz with a on/reset button only and a auto off.. All I want to do is weight it and weight it fast. I use the Ardent system now and just put oz as tents. So you never go past 9 oz ie 9 tents. the final check before one goes back is a balance beam between the two lowest weights in the well anyway
