A 3m whip, chair, net, disgorger... job done
I was an Angling Coach for 11 years... a whip is always first port of call for youngsters... a cheap whip is about a fiver, a cheap rig can cost a couple of quid, you'll no doubt have a net and disgorger... and a little chair, the Range do some kids chairs...
Get rigs with barbless hook just in case of the odd accident... keep the session down to 2 hours max if your lad has attention deficit...and go to a prolific venue... nowt worse than blanking...
tight lines..👍
