Are you still using a scoop and using the mask to better see where the target is or are you diving down to the target to recover it?
I use mask to see my coil - I get target - can see where I need to scoop and do it
I did the put your foot next to or behind coil thing in the early years - it would take a minimum of twice as long to recover most targets
with a mask in clear water - theres no arguing - I can see exactly where to stick scoop in - I can see items before I scoop sometimes - I can see if item falls out or off the lip - such as sunglasses I hit at wrong angle - or chains that slide over the edge - I can spot small stud earings and small weights that fall threw
I can see the item in the scoop in the water and remove it waist deep instead of pulling scoop completely out of the water which is tough for guys hitting chest deep
with waders
Ive turned a lot of hunters to using a mask with or without a snorkel over the years and they all notice they can retrieve faster
wearing a mask I have found close to $300 in paper money - found about 20 old bottles - found rare shells and other non metallic items too
I can spot underwater troughs - blown out rocky areas and other spots easier
in very rocky - shelly - or mucky areas - I will use a floating sifter - which can speed recovery also - must time I wear gloves and in thick sand or muck
I will stick my hand in and churn the soil out quickly in the scoop which speeds recovery - have seen guys stand there and shake scoop for 5 mins trying to get muck
out - when I know I have target in my scoop - I start to swing as sand filters out - instead of just waiting and will usually wait till I get another signal to see what I got
from last hit - some times will do this when using sifter - especially in thick or mucky spots - will wait till I got 3 targets in the sifter and then pluck them out
all these things plus a few others can speed your recovery - but I feel naked without a mask
if you don't feel comfortable wearing a mask - carry a pair of goggles on top your forehead or around your neck - theyre cheap and lite
I can tell you about 9 out of 10 vets I turned onto wearing a mask - still do - so that says something
